How much gas does Russia produce

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

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 crackle of firewood in the furnace. Heating with solid fuel is always soot, smoke and soot, the need for annual repainting of ceilings. And besides the troubles associated with constant dirt, it is also necessary to procure or purchase and store a supply of firewood somewhere for the whole winter.

Unfortunately, natural pipeline gas is not installed everywhere. In many settlements, residents have to be content with gas in cylinders. And people are interested in how many liters of gas are in a 50-liter bottle?

Recall the basics of school organic chemistry. Methane is the first saturated hydrocarbon. 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, respectively, it passes into a gaseous state. Butane has this range: -138.3 ... -0.5 ° С. As you can see, the liquid transition temperatures for both gases are not much below zero, which makes 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 a liquefied mixture. They act a little differently when supplying high-rise buildings with gas. Well, how many liters of gas can fit in a 50-liter bottle?

And to change cylinders with 42 liters of gas (this is how much liquefied gas is stored in a cylinder) plus the weight of the cylinder itself on all floors and apartments ... Therefore, in such cases, in the courtyard of the house, as a rule, a grounded storage is arranged, into which the gas mixture is delivered by special gas carriers. In a special device, it is transferred to the 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 bottle? To answer this question, it is necessary to decide which gas we are interested in. 42 liters of liquid mixture of gases are poured into the cylinder. But how much is it in kilograms, cubic meters? The density of liquefied: 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, we will make small calculations.

Propane
Liquid phase density	0,53	kg/l
Liters in a bottle	42,00	l
The mass of gas in the cylinder	22,18	kg
Density of the gaseous phase	1,87	kg/m3
Volume occupied by 42 kg of gas (1 cylinder)	22,44	m3
Butane
Liquid phase density	0,60	kg/l
Liters in a bottle	42,00	l
The mass of gas in the cylinder	25,24	kg
Density of the gaseous phase	2,52	kg/m3
Volume occupied by 42 kg of gas (1 cylinder)	16,67	m3

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 the cylinder in equal proportions, 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 plates and labels from cylinders.
Do not lift or move the cylinder by holding on to the valve.
Leaks should be checked with soapy water, not with a lit match.
Open the cylinder valve smoothly.
Never heat the balloon.
Independent pumping (overflow) of liquefied gas into other containers is prohibited.

Who buys gas from Russia

The main consumers and buyers of our natural gas are European countries.The main importers of gas are such countries as the Republic of Turkey, Italy and Germany. These countries buy gas in large volumes. Many countries in Europe depend on Russian gas. Belarus and Armenia buy gas only from Russia, so they are 100% dependent on our supplies in 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 in the world market is more than $400. Also, Finland, Latvia, Bulgaria, Lithuania and Estonia are completely dependent on Russian gas. These states, except Finland, pay for gas 419 conventional units per thousand cubic meters. Of course, we are not doing well 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 our gas supplies. Recently, imports of natural gas to China have been discussed. Projects for the construction of the 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.

One can draw a small conclusion that Russian natural gas must be used rationally. This is a raw material that must be preserved for 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

Notes of a Traveling Locksmith - Malaga Truth

How much gas is in the bottle

Oxygen, argon, helium, welding mixtures: 40 liters cylinder at 150 atm - 6 cubic meters Acetylene: 40 liters cylinder at 19 atm - 4.5 cubic meters Carbonic acid: 40 liters cylinder - 24 kg - 12 cubic meters Propane: 50 liters cylinder - 42 liters of liquid gas - 21 kg - 10 cubic meters.

The pressure of oxygen in the cylinder depending on the 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 in length

0.6 - 2.222 kg 0.8 - 3.950 kg 1.0 - 6.173 kg 1.2 - 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 with a semiautomatic device with a 0.8 mm wire cassette weighing 5 kg and a carbon dioxide cylinder with a volume of 10 liters? 5 kg approximately 1200 meters of wire. If the average feed rate for such a 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 converted to a “small” 10-liter cylinder, then there will be 3 cubic meters of carbon dioxide in it. meters or 3000 liters. If the gas flow rate for purge is 10 liters per minute, then a 10-liter cylinder should last 300 minutes or for 1 cassette of 0.8 wire weighing 5 kg, or a “large” 40-liter cylinder for 4 cassettes of 5 kg each.

Question: I want to put a gas boiler in the country and be heated from cylinders, how long will one cylinder last? Answer: In a 50-liter “large” propane cylinder there are 21 kg of liquefied gas or 10 cubic meters of gas in gaseous form. We find the data of the boiler, for example, take the very common AOGV-11.6 boiler with a capacity of 11.6 kW and designed for heating 110 square meters. meters. On the ZhMZ website, the consumption is immediately indicated 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 requirement for air temperature in it, and if it is outside will be only -20C, then 1 cylinder will be enough 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 bottles 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 in boilers, it is usually necessary to change jets / nozzles. When making calculations, be sure to take this into account and take the consumption 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 "Steel cylinders of small and medium size 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 "Technical and medical gaseous 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

TO₁ = (0.968P + 1) * *

P is the gas pressure in the cylinder, measured by a manometer, kgf/cm2;

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

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

Z is the oxygen combustion coefficient at temperature t.

The values of the coefficient K1 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). The 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 that of butane is 580 kg/m3. Propane in a gaseous state at atmospheric pressure and a temperature of 15 ° C is 1.9 kg / m3, and butane - 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: a volume of 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 \u003d 50dm3 \u003d 0.05m3;

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

But due to the limitation of gas pressure of 1.6 MPa on the walls, more than 21 kg are not 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 cylinders for acetylene can be viewed in accordance with GOST 949-73 "Steel cylinders of small and medium size 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 a 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 weight (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 \u003d 0.07 • E • (P - 0.1)

0.07 is a coefficient that takes into account the amount of acetone in the cylinder and the solubility of acetylene.

E - water volume of the cylinder in cubic dm;

Р – cylinder pressure, MPa (pressure 1.9 MPa (19.0 kgf/cm2) at 20 °С according to GOST 5457-75 “Technical dissolved and gaseous acetylene”);

0.1 - atmospheric pressure in MPa;

Weight of 1 m3 of acetylene at 0°C and 760 mm Hg. is - 1.17 kg.

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

Let's calculate the volume of acetylene in a 40 l 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) = 5.04m3

The weight of acetylene in a cylinder with a volume of 40 l 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 (carbonic acid)

Carbon dioxide (according to GOST 8050-85 "Carbon dioxide gaseous and liquid") is used as a shielding gas for electric welding. Composition of the mixture: CO2; Ar + CO2 ; Ar + CO2 + O2. Manufacturers can also label it as a mixture of MIX1 - MIX5.

At an operating pressure of carbon dioxide in a cylinder of 14.7 MPa (150 kgf/cm2), the filling factor is 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).

Calculate the volume of carbon dioxide in the gaseous state:

24kg / 1.98kg / 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, during flooring or repairing certain types of roofs, liquefied gas is used. When estimate documentation is compiled for the performance of work related to the use of gas, estimators sometimes face 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 the estimate documentation, when calculating, the international system of units SI is most often used, in which a cubic meter is taken as a unit of volume. To calculate the number of gas cylinders and determine their cost, m3 must be converted to liters.

Density is the quantitative value of the mass in kilograms placed in a cubic meter. It's very variable and depends on a lot of 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 in a cube does not work in our case. 1 m 3 contains 1000 liters of air, water or other substance in a normal state. However, the cylinders contain liquid gas, and it is there at high pressure and low temperature. For use, the substance must be brought into the gaseous phase, while its volume increases many times over.

To convert propane-butane gas from cubic meters of gaseous gas to liters of liquid gas, it is necessary to know the density of the liquid gas and the specific gravity of the substance. The 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 the laboratory. In the calculations, we can use the average indicator.

How to make a calculation?

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 a ratio of 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 \u003d 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 \u003d Kilogram / Density

So, 27 cubic meters of gaseous propane-butane are equal to 114 liters of liquefied gas. In order to avoid using formulas each time converting m 3 into liters, we derive the ratio: 27 m 3 \u003d 107 l, therefore 1 m 3 \u003d 4.2 l. Using reference data and simple formulas, you can easily make calculations that help in budgeting.

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 \u003d Liter * Density

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

How much m3 in a cylinder

50l \u003d 50dm3 \u003d 0.05m3;

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

But due to the limitation of gas pressure of 1.6 MPa on the walls, more than 21 kg are not 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 in a cylinder of 50 liters 21 kilograms of gas are filled, for which the test density is 0.567. To calculate liters, you need to divide 21 by 0.567. It turns out 37.04 liters of gas.

Calorific value of natural gas kcal m3

Information

Articles about VO

Physical quantities

The heat output of heating equipment is usually presented in kilowatts (kW), kilocalories per hour (kcalh) or megajoules per hour (MJh).

1 kW = 0.86 kcal/h = 3.6 MJ/h

Energy consumption is measured in kilowatt-hours (kWh), kilocalories (kcal) or megajoules (MJ).

1 kWh = 0.86 kcal = 3.6 MJ

Most household heating appliances have a capacity of

within 10 - 45 kW.

Natural gas

Natural gas consumption is usually measured in cubic meters (m3). This value is recorded by your gas meter and it is the gas worker who records it when he takes readings. One cubic meter of natural gas contains 37.5 MJ or 8,958 kcal of energy.

Propane (liquefied gas, LPG)*

Propane consumption is usually measured in liters (l). One liter of propane contains 25.3 MJ or 6,044 kcal of energy. Basically, all the rules and concepts that apply to natural gas apply to 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 about 3% less than that of natural gas. This suggests that traditional propane fuel pumps are slightly more productive than those fueled by natural gas. On the other hand, when we are dealing with high-efficiency 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 proportion of propane can range from 20 to 80%. Butane has a calorie content of 6,742 kcal.

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

Best Answers

Engineer:

The composition of household gas is fundamentally unknown, since three grades of it are produced and sold for household needs: • SPBTZ - a mixture of propane and butane technical winter (up to 70% propane); • SPBTL - summer mixture of propane and butane technical (up to 70% butane) • BT - technical butane (96-98% butane). For a summer mixture, 230 liters of gas will be obtained from a liter, and 253 liters from a winter mixture.

But the filling of the cylinder is not more than 80% (UN BEC rule) of its capacity (since liquid gas expands greatly - this is necessary so that the full one does not explode). Therefore, in a full 50-liter cylinder, there should be no more than 40 liters of gas.

Total from 9200 to 10120 liters can be.

Technical gases in cylinders of 50 liters

Technical gases (for more details see http://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 for welding and other construction work.

Types of technical gases

There are many types of technical gases obtained by any of these methods. The main ones include:

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 special devices and apparatus are used - air separators.

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

In addition to the main types of industrial gases, medical gases can also be distinguished, 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 are often used, which consist of several gas components. The use of such a mixture helps to significantly improve the result of work. Welding gas mixtures are in particular demand, which include such as a protective gas mixture, 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.

How many cubic meters of technical gas are in a domestic cylinder

Gas cylinders http://www.nvph.ru/gazovie_ballony are designed for storage and transportation of various types of gases. The usual cylinder, which is used most often, has a volume of 50 liters, but since each gas has a different molecular weight, the amount of gas it contains is different.

One propane tank, for heating the house, is enough for a maximum of a week, depending on the size of the premises. For example, for heating a house with an area of 110 square meters. m in severe frosts, you will need one cylinder per day. If you use a gas cylinder only for cooking at home, it will last for a month or more.

When using cylinders for welding, it is necessary to calculate that one cylinder with a volume of 10 liters will be enough for 300 minutes of work. Otherwise, you should rely on the power of the equipment and the duration of the work.
