Can the cylinder be refilled at gas stations?

Are you deciding where to refill your gas cylinder? Is it possible to refill gas cylinders at automobile gas stations, since automobile gas cylinders are refilled there? A multivalve is installed on a car gas cylinder. The multivalve stops gas supply to the cylinder when the filling level reaches 85%. Thanks to the multi-valve, there is no excess pressure in the car gas cylinder. Household gas cylinders are not equipped with protective multi-valves, so they need to be refilled only in specialized weighing systems. Why is excess gas pressure in a cylinder dangerous? Because gas has a high expansion coefficient, and when heated, it can build up high pressure in the cylinder, exceeding technically permissible standards. As an example, the following information can be provided. If a charged 50 liter propane gas cylinder is exposed to an open fire, the excess pressure ruptures the cylinder and it flies more than 250 meters. To avoid turning a cylinder into a destructive missile, do not charge it at gas stations! Cylinders must be filled at the weighing station to a level of 85%. At gas stations, liquid gas is sold in liters, not kilograms, which makes it difficult to understand how much gas is actually filled into the cylinder. Meters at gas stations have an error, because... they break very often, so this error is adjusted not in favor of the buyer.

To check how much gas is left in the cylinder, you can use a regular home scale. The information below will help you calculate the amount of gas in the cylinder.

How many liters of gas are in a 50-liter cylinder How many cubic meters of gas are in a 50-liter cylinder

When gas comes to a rural settlement, civilization comes to it.
Stove heating, or individual water heating with a solid fuel boiler, is not only the romantic crackling of firewood in the firebox. Heating with solid fuel always means soot, smoke and soot, and the need for annual repainting of the ceilings. And besides the troubles associated with constant dirt, you also need to prepare or purchase and somewhere store a supply of firewood for the whole winter. Unfortunately, natural pipeline gas is not installed everywhere. In many settlements, residents have to make do with bottled gas. And people are wondering how many liters of gas are in a 50-liter cylinder?

Let's remember the basics of school organic chemistry. The first saturated hydrocarbon is methane. The molecule of this gas consists of one carbon atom surrounded by four hydrogen atoms.

• methane CH4;
• ethane C2H6;
• propane C3H8;
• butane C4H10.

The last two compounds - propane and butane - are the contents of household gas cylinders.

Physical properties of these chemicals

Propane at normal atmospheric pressure is a liquid in the temperature range from –187.7 to –42.1 °C. Below the specified interval, propane crystallizes, and above, accordingly, it passes into the gaseous state. Butane has this range: –138.3 … –0.5 °C. As you can see, the transition temperatures into liquids for both gases are not much below zero, making them quite easy to liquefy by increasing the pressure.

Gas storage methods

In everyday life, as a rule, a propane-butane mixture is used. In private homes, standard 50-liter gas cylinders are used to store the liquefied mixture. They act a little differently when supplying gas to high-rise buildings. Well, how many liters of gas can fit in a 50-liter cylinder?

And to change cylinders with 42 liters of gas (this is exactly how much liquefied gas is stored in the cylinder) plus the weight of the cylinder itself on all floors and apartments... Therefore, in such cases, as a rule, a grounded storage facility is installed in the courtyard of the house, into which the gas mixture is delivered by special gas carriers. In a special device it is converted into a gaseous phase and in this form enters the household pipeline.

Gas cylinder volume

So how many cubic meters of gas are in a 50-liter cylinder? To answer this question, we need to decide what gas we are interested in. 42 liters of liquid mixture of gases are poured into the cylinder. But how much is this in kilograms, cubic meters? Density of liquefied liquids: propane – 0.528 kg/l, butane – 601 kg/l.

In order to find out how many liters of gas are in a 50-liter cylinder, let’s make some small calculations.

Thus, how many liters of gas are in a 50-liter cylinder depends on what composition is pumped into it. If we assume that the cylinder is filled with one propane - 22.44 m3, butane - 16.67 m3. But since a mixture of these chemical compounds is used in everyday life, the indicator will be somewhere in the middle.

If we assume that propane and butane are in equal proportions in the cylinder, then the answer to the question of how much gas is in a 50-liter cylinder (m3) is about 20.

Safety precautions when handling gas cylinders

• Never remove signs or labels from cylinders.
• Do not lift or move the cylinder while holding the valve.
• Determine leaks using a soap solution rather than a lit match.
• Open the cylinder valve smoothly.
• Never heat the cylinder.
• Independent pumping (transfer) of liquefied gas into other containers is prohibited.

Types of repairs

You can understand that the cylinder requires repair by the following signs:

• the valve is faulty, there are cracks in the pressure gauge;
• damaged, dislodged shoe;
• the neck thread is worn or faulty;
• the seal is broken;
• color mismatch.

Such containers must be urgently delivered to a specialized organization for troubleshooting.

If gross violations are discovered during the repair, it will be sent for disposal:

• significant external damage: dents, corrosion, cracks;
• absence or unclearness of the passport, markings;
• cracks on the weld a third of the length.

An experienced technician will solve the remaining problems. Independent attempts to repair vessels are prohibited.

Who buys gas from Russia

The main consumers and buyers of our natural gas are European countries. The main importers of gas are countries such as the Republic of Türkiye, Italy and Germany. These countries buy gas in large volumes. Many European countries depend on Russian gas. Belarus and Armenia buy gas only from Russia, so they are 100% dependent on our supplies for this component. These fraternal countries buy gas from us for an average of $170 per thousand cubic meters. Although the average price of natural gas on the world market is more than $400. Finland, Latvia, Bulgaria, Lithuania and Estonia are also completely dependent on Russian gas. These states, except Finland, pay 419 conventional units per thousand cubic meters for gas. Of course, not everything is good with these countries, but we also cannot lose customers with whom we directly border. Countries such as the Czech Republic, Ukraine, Turkey, Slovakia and Poland depend on 60-70% of Russian gas supplies. Although Ukraine and Turkey want to stop importing our gas, it will be extremely difficult for them to find a replacement. Italy, France, the Netherlands and many others also depend on 20-40% of the supply of our gas. Recently, the import of natural gas into China has been discussed. Projects for the construction of a gas pipeline are already ready. This is a very good chance for Russia not only to enter the Asian market, but also to create the necessary competition there.

A small conclusion can be drawn that Russian natural gas must be used rationally. These are raw materials that need to be preserved by our children, grandchildren and great-grandchildren.

Now there are many local wars over resources, so you need to pay attention to the security of not only the country, but also gas fields

How much does a bucket of tomatoes weigh?

How many cubic meters of gas are in a 50 liter propane cylinder?
The weight of a bucket of tomatoes largely depends on the variety, that is, the size of the tomatoes, their shape and their density. After all, there are denser and heavier tomatoes, and there are soft and lighter ones. But on average, a bucket of tomatoes pulls 9 kilograms.

A 10 liter bucket of tomatoes weighs 9 - 10 kg.

If there are fewer voids between the tomatoes, then the tomato can yield all of ten kilograms, if there are more, then eight. If you look at the reference tables, they show the volumetric density of tomatoes, that is, the density taking into account the air space between them, and indicate that exactly 10 kilograms of tomatoes fit in a ten-liter bucket. In practice, they fit a little less.

How much gas is in the cylinder

Oxygen, argon, helium, welding mixtures: 40 liter cylinder at 150 atm - 6 cubic mAcetylene: 40 liter cylinder at 19 atm - 4.5 cubic mCarbon dioxide: 40 liter cylinder - 24 kg - 12 cubic mPropane: 50 liter cylinder – 42 liters of liquid gas – 21 kg – 10 cubic meters.

Oxygen pressure in the cylinder depending on temperature

-40С – 105 atm-20С – 120 atm0С – 135 atm+20С – 150 atm (nominal)+40С – 165 atm

Welding wire Sv-08 and its derivatives, weight 1 kilometer along the length

0.6 – 2.222 kg0.8 – 3.950 kg1.0 – 6.173 kg1.2 – 8.888 kg

Calorific value (calorific value) of liquefied and natural gas

Natural gas – 8500 kcal/m3 Liquefied gas – 21800 kcal/m3

Examples of using the above data

Question: How long will gas and wire last when welding semi-automatically with a cassette of 0.8 mm wire weighing 5 kg and a cylinder of carbon dioxide with a volume of 10 liters? Answer: Welding wire SV-08 with a diameter of 0.8 mm weighs 3.950 kg 1 kilometer, which means on the cassette 5 kg approximately 1200 meters of wire. If the average feed speed for such wire is 4 meters per minute, then the cassette will go in 300 minutes. Carbon dioxide in a “large” 40-liter cylinder is 12 cubic meters or 12,000 liters; if you convert it to a “small” 10-liter cylinder, then it will contain 3 cubic meters of carbon dioxide. meters or 3000 liters. If the gas consumption for purging is 10 liters per minute, then a 10-liter cylinder should be enough for 300 minutes or for 1 cassette of 0.8 wire weighing 5 kg, or a “large” cylinder of 40 liters for 4 cassettes of 5 kg each.

Question: I want to install a gas boiler at my dacha and use cylinders for heating, how long will one cylinder last? Answer: A 50-liter “large” propane cylinder contains 21 kg of liquefied gas or 10 cubic meters of gas in gaseous form. We find the boiler data, for example, take the very common AOGV-11.6 boiler with a power of 11.6 kW and designed for heating 110 square meters. meters. The ZhMZ website indicates the consumption in kilograms per hour for liquefied gas - 0.86 kg per hour when operating at full capacity. We divide 21 kg of gas in a cylinder by 0.86 kg/hour = 18 hours of continuous burning of such a boiler on 1 cylinder. In reality, this will happen if it is -30C outside with a standard house and the usual requirements for the air temperature in it, and if outside If it is only -20C, then 1 cylinder will last for 24 hours (day). We can conclude that in order to heat an ordinary house of 110 square meters. meters of bottled gas in the cold months of the year you need about 30 cylinders per month. It must be remembered that due to the different calorific value of liquefied and natural gas, the consumption of liquefied and natural gas at the same power for boilers is different. To switch from one type of gas to another, boilers usually need to change jets/nozzles. When making calculations, be sure to take this into account and take the flow data specifically for a boiler with jets for the correct gas.

Calculation of gas in a cylinder

How to calculate the amount of gas in a cylinder:

Oxygen

The parameters and dimensions of oxygen cylinders can be viewed according to GOST 949-73 “Small and medium steel cylinders for gases at Рр ≤ 19.7 MPa”. The most popular are cylinders with volumes of 5, 10 and 40 liters.

According to GOST 5583-78 “Gaseous technical and medical oxygen” (Appendix 2), the volume of gaseous oxygen in a cylinder (V) in cubic meters under normal conditions is calculated by the formula:

Vb — cylinder capacity, dm3;

K1 - coefficient for determining the volume of oxygen in the cylinder under normal conditions, calculated by the formula

K1 = (0.968P + 1) * *

P - gas pressure in the cylinder, measured by a pressure gauge, kgf/cm2;

0.968 — coefficient for converting technical atmospheres (kgf/cm2) into physical ones;

t is the gas temperature in the cylinder, °C;

Z is the oxygen combustion coefficient at temperature t.

The values ​​of the K1 coefficient are given in Table 4, GOST 5583-78.

Let's calculate the volume of oxygen in the most common cylinder in construction: a volume of 40 liters with a working pressure of 14.7 MPa (150 kgf/cm2). Coefficient K1 is determined according to Table 4, GOST 5583-78 at a temperature of 15°C:

V = 0.159 • 40 = 6.36m3

Conclusion (for the case under consideration): 1 cylinder = 40l = 6.36m3

Propane-butane

The parameters and dimensions of oxygen cylinders for propane, butane and their mixtures can be viewed according to GOST 15860-84. Currently, four types of these products are used, with volumes of 5, 12, 27 and 50 liters.

Under normal atmospheric conditions and a temperature of 15°C, the density of propane in the liquid state is 510 kg/m3, and butane 580 kg/m3. Propane in the gas state at atmospheric pressure and temperature 15°C is 1.9 kg/m3, and butane is 2.55 kg/m3. Under normal atmospheric conditions and a temperature of 15°C, 0.392 m3 of gas is formed from 1 kg of liquid butane, and 0.526 m3 from 1 kg of propane.

Let's calculate the weight of the propane-butane mixture in the most common cylinder in construction: volume 50 with a maximum gas pressure of 1.6 MPa. The proportion of propane according to GOST 15860-84 must be at least 60% (note 1 to Table 2):

50l = 50dm3 = 0.05m3;

0.05 m3 • (510 • 0.6 + 580 •0.4) = 26.9 kg

But due to the gas pressure limitation of 1.6 MPa on the walls, more than 21 kg cannot be filled into a cylinder of this type.

Let's calculate the volume of the propane-butane mixture in the gaseous state:

21kg • (0.526 • 0.6 + 0.392 •0.4) = 9.93m3

Conclusion (for the case under consideration): 1 cylinder = 50l = 21kg = 9.93m3

Acetylene

The parameters and dimensions of acetylene cylinders can be viewed according to GOST 949-73 “Small and medium steel cylinders for gases at Рр ≤ 19.7 MPa”. The most popular are cylinders with volumes of 5, 10 and 40 liters. The body of an acetylene cylinder differs from the body of an oxygen cylinder in its smaller size.

At a pressure of 1.0 MPa and a temperature of 20 °C, a 40-liter cylinder holds 5–5.8 kg of acetylene by mass (4.6–5.3 m3 of gas at a temperature of 20 °C and 760 mm Hg).

The approximate amount of acetylene in the cylinder (determined by weighing) can be determined by the formula:

Va = 0.07 • E • (P – 0.1)

0.07 – coefficient, which takes into account the amount of acetone in the cylinder and the solubility of acetylene.

E – water volume of the cylinder in cubic dm;

P – pressure in the cylinder, MPa (pressure 1.9 MPa (19.0 kgf/cm2) at 20 °C according to GOST 5457-75 “Dissolved and gaseous technical acetylene”);

0.1 – atmospheric pressure in MPa;

Weight of 1 m3 of acetylene at a temperature of 0°C and 760 mmHg. is 1.17 kg.

Weight of 1 cubic meter of acetylene at a temperature of 20°C and 760 mmHg. is 1.09 kg.

Let's calculate the volume of acetylene in a 40 liter cylinder with a working pressure of 1.9 MPa (19 kgf/cm2) at a temperature of 20°C:

Va = 0.07 • 40 • (1.9 – 0.1) = 5.04 m3

Weight of acetylene in a 40 liter cylinder with a working pressure of 1.9 MPa (19 kgf/cm2) at a temperature of 20°C:

Conclusion (for the case under consideration): 1 cylinder = 40l = 5.5kg = 5.04m3

Carbon dioxide (carbon dioxide)

Carbon dioxide (according to GOST 8050-85 “Gaseous and liquid carbon dioxide”) is used as a shielding gas for electric welding work. Mixture composition: CO2; Ar + CO2 ; Ar + CO2 + O2. Manufacturers can also label it as a mixture of MIX1 - MIX5.

The parameters and dimensions of acetylene cylinders can be viewed according to GOST 949-73 “Small and medium steel cylinders for gases at Рр ≤ 19.7 MPa”. The most popular are cylinders with volumes of 5, 10 and 40 liters.

At a working pressure of carbon dioxide in the cylinder of 14.7 MPa (150 kgf/cm2), filling factor: 0.60 kg/l; at 9.8 MPa (100 kgf/cm2) – 0.29 kg/l; at 12.25 MPa (125 kgf/cm2) – 0.47 kg/l.

The volumetric weight of carbon dioxide in the gaseous state is 1.98 kg/m³, under normal conditions.

Let's calculate the weight of carbon dioxide in the most common cylinder in construction: a volume of 40 liters with a working pressure of 14.7 MPa (150 kgf/cm2).

Let's calculate the volume of carbon dioxide in the gaseous state:

24kg / 1.98 kg/m3 = 12.12m3

Conclusion (for the case under consideration): 1 cylinder = 40l = 24kg = 12.12m3

Propane butane gas how to convert cubic meters to liters

When performing construction work, for example, when laying or repairing certain types of roofing, liquefied gas is used. When estimate documentation is drawn up for work related to the use of gas, estimators are sometimes faced with a problem: how to convert cubic meters into liters. The fact is that liquefied gas is most often supplied in cylinders, the volume of which is measured in liters. In estimate documentation, calculations most often use the international system of SI units, in which a cubic meter is taken as a unit of volume. To calculate the number of gas cylinders and determine their cost, you must convert m3 to liters.

Density is the quantitative value of mass in kilograms placed in a cubic meter. A very ambiguous value and depends on many factors. The main one is temperature. So, the density of propane-butane can vary from 490 to 619 kg/m3.

What do you need to know?

We must immediately make a reservation that a simple calculation based on how many liters are in a cube does not work in our case. 1 m3 contains 1000 liters of air, water or other substance in normal condition. However, the cylinders contain liquid gas, and it is there at high pressure and low temperature. To use the substance, it must be brought into the gaseous phase, and its volume increases many times over.

The parameters and dimensions of oxygen cylinders for propane, butane and their mixtures can be viewed according to GOST 15860-84. Currently, four types of these products are used, with volumes of 5, 12, 27 and 50 liters.

To convert propane butane gas from cubic meters of gaseous to liters of liquid gas, you need to know the density of the liquid gas and the specific gravity of the substance. Density depends on the temperature and proportions of the propane-butane mixture, and is easily determined using tables. The specific gravity of propane-butane is determined in laboratory conditions. In calculations we can use the average indicator.

How to perform the calculation?

Under normal atmospheric conditions and a temperature of 15°C, the density of propane in the liquid state is 510 kg/m3, and butane 580 kg/m3. Propane in the gas state at atmospheric pressure and temperature 15°C is 1.9 kg/m3, and butane is 2.55 kg/m3. Under normal atmospheric conditions and a temperature of 15°C, 0.392 m3 of gas is formed from 1 kg of liquid butane, and 0.526 m3 from 1 kg of propane.

Knowing the volume of a gas and its specific gravity, we can determine its mass. So, if the estimate indicates 27 m 3 of technical propane-butane, then multiplying 27 by 2.25 we find out that this volume weighs 60.27 kg. Now, knowing the density of liquefied gas, you can calculate its volume in liters or cubic decimeters. The density of propane-butane in the ratio 80/20 at a temperature of 10 0 C is 0.528 kg/dm 3. Knowing the formula for the density of a substance (mass divided by volume), we can find the volume of 60.27 kg of gas. It is 60.27 kg / 0.528 kg/dm 3 = 114.15 dm 3 or 114 liters.

How to convert propane-butane from kilograms to liters?

In order to calculate the number of liters in one kilogram of gas, you need to use the formula: Liter=Kilogram/Density

So, 27 cubic meters of propane-butane gas are equal to 114 liters of liquefied gas. In order to avoid using formulas each time when converting m3 to liters, we derive the ratio: 27 m3 = 107 l, therefore 1 m3 = 4.2 l. Using reference data and simple formulas, you can easily make calculations that help in drawing up estimates.

How to convert propane-butane from liters to kilograms?

In order to calculate how many kilograms are contained in one liter of gas, you need to use the formula: Kilogram = Liter * Density

Example: It is known that a car is filled with 100 liters of gas with a density of 0.53. To calculate the number of kilograms of gas, you need to multiply 100 by 0.53. You will get 53 kg of gas.

How many m3 is in a cylinder?

Let's calculate the weight of the propane-butane mixture in the most common cylinder in construction: volume 50 with a maximum gas pressure of 1.6 MPa. The proportion of propane according to GOST 15860-84 must be at least 60% (note 1 to Table 2):

50l = 50dm3 = 0.05m3;

0.05 m3 • (510 • 0.6 + 580 •0.4) = 26.9 kg

But due to the gas pressure limitation of 1.6 MPa on the walls, more than 21 kg cannot be filled into a cylinder of this type.

Let's calculate the volume of the propane-butane mixture in the gaseous state:

21kg • (0.526 • 0.6 + 0.392 •0.4) = 9.93m3

Conclusion (for the case under consideration): 1 cylinder = 50l = 21kg = 9.93m3

Example: It is known that a 50-liter cylinder contains 21 kilograms of gas, whose test density is 0.567. To calculate liters you need to divide 21 by 0.567. The result is 37.04 liters of gas.

Calculation example

It is necessary to determine how many cubic meters of gas one cylinder with a 50-liter propane-butane mixture contains if you pass its contents through a gas meter:

• the mass of the gas mixture pumped into it is about 21 kilograms;
• volume in m³ is equal to 50/5 = 10;
• after adjusting for the filling of the cylinder, we get 10 × 0.85 = 8.5 m³.

This indicator may vary depending on the ambient temperature, since when it decreases, the pressure inside the container decreases, with a corresponding decrease in the volume of fuel.

But the use of liters of gas in cubic meters is only relevant as an approximate calculation. When purchasing this type of fuel, kilograms of the gas mixture and the pressure inside the container are important, and when using individual metering devices, a standard unit of measurement is used - cubic meters, the conversion procedure of which does not depend on the composition of the gas and is determined by a simple arithmetic calculation in the ratio of 1 to 1000.

Basically, all the rules and concepts that apply to natural gas are also suitable for propane, with a slight adjustment for calorie content. Propane has a lower hydrogen content than natural gas. When propane is burned, the amount of heat released in latent form is approximately 3% less than that of natural gas. This suggests that traditional propane-fueled furnaces are slightly more productive than those fueled by natural gas. On the other hand, when we are dealing with highly efficient condensing heaters, the reduced hydrogen content complicates the condensation process and propane heaters are slightly inferior to those that run on natural gas.

* Unlike Canada, in Ukraine it is not pure propane that is common, but propane - butane mixtures, in which the share of propane can range from 20 to 80%. Butane has a caloric content of 6,742 kcal

It is important to remember that the boiling point of propane is minus 43°C, and the boiling point of butane is only minus 0.5°C. In practice, this leads to the fact that with a high butane content in a gas cylinder in the cold, the gas from the cylinder does not evaporate without additional heating

How many cubic meters of gas are in a 50 liter cylinder?

Technical gases in 50 liter cylinders

Technical gases (for more details see here https://www.nvph.ru/texnicheskie-gazyi) are special substances obtained from the atmosphere, during a chemical reaction, as well as from hydrocarbon raw materials. Technical gases are used for industrial and domestic purposes, as well as when performing welding and other construction work.

Types of technical gases

There are many types of technical gases obtained by any of the above methods. Among the main ones we can highlight the following:

• Oxygen.

Nitrogen.

Argon.

Carbon dioxide.

Helium.

Propane.

Acetylene.

The gases oxygen, nitrogen, carbon dioxide and argon are obtained by dividing air into two components - oxygen and nitrogen, for this purpose special devices and apparatus are used - air separators.

Helium is obtained by extracting helium-containing natural gases, propane https://www.nvph.ru/Propan-gaz is produced during the extraction of carbon raw materials. By a chemical method, acetylene is produced by adding water and calcium carbide through a chemical reaction.

In addition to the main types of technical gases, one can also distinguish medical gases, which are actively used in the operation of many devices, as well as in some therapeutic and resuscitation procedures. An example of such a substance is medical oxygen.

In addition, in modern industry, gas mixtures that consist of several gas components are very often used. The use of such a mixture helps to significantly improve the result of work. Welding gas mixtures are in particular demand, which include protective gas mixtures, the main components of which are argon and carbon dioxide, as well as test gas mixtures used in metrology, created on the basis of pure technical gas.

Conclusions and useful video on the topic

From this video you can find out how long it takes for water to boil, and, therefore, how long a propane tank with a burner will last:

Before calculating the time for which a propane cylinder of a certain volume will last, you need to find out the maximum consumption of the gas equipment used. Often this information is indicated in the technical documentation of the device, be it a gas stove or a heating boiler.

According to the formula, to calculate the time of use of a gas cylinder, it is necessary to divide the amount of propane inside the cylinder by the fuel consumption of a specific gas appliance. Based on this, you can calculate how long both a camp cylinder for a gas burner and a household 50 liter cylinder for using gas appliances will last.
