When gas comes to a rural locality, civilization comes to it. Stove heating, or individual water heating with a solid fuel boiler, is not only a romantic crackling of firewood in a firebox. 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 prepare or purchase and somewhere to store a supply of firewood for the whole winter.
Unfortunately, natural pipeline gas has not been conducted everywhere. In many settlements, residents have to be content with gas in cylinders. And people are interested, but how many liters of gas are in a 50-liter cylinder?
What is household gas
Recall 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.
If the chain is slightly lengthened — instead of one of the hydrogen atoms, “attach” one carbon, to attach the hydrogen atoms to the remaining three of its bonds - you get the next member of the family of saturated hydrocarbons, ethane.
Starting from the beginning of the chain, we have:
- methane CH 4 ;
- ethane C 2 H 6 ;
- propane C 3 H 8 ;
- butane C 4 H 10 .
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 this gap, propane crystallizes, and above, accordingly, it passes into a gaseous state. Butane has this range: –138.3 ... –0.5 ° . As you can see, the transition temperatures into the liquid for both gases are not much lower than zero, which makes them easy to liquefy, increasing pressure.
Gas storage methods
In everyday life, a propane-butane mixture is used, as a rule. In private houses, standard 50-liter gas cylinders are used to store liquefied mixture. They act a little differently when supplying gas to high-rise buildings. Well, how many liters of gas in a 50-liter bottle can fit?
And to change cylinders with 42 liters of gas (that is how much liquefied gas is stored in the cylinder) plus the weight of the cylinder for all floors and apartments ... Therefore, in such cases, as a rule, a grounded storage is arranged in the courtyard of the house, to 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 bottle capacity
So how many cubic meters of gas are in a 50 liter bottle? To answer this question, it is necessary to decide which gas interests us. A liquid mixture of gases is poured into the cylinder 42 liters. But how much is this 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 do some small calculations.
Propane |
Liquid phase density | 0.53 | kg / l |
Liters in a cylinder | 42.00 | l |
Mass of gas in the cylinder | 22.18 | kg |
Gaseous density | 1.87 | kg / m 3 |
Volume occupied by 42 l of gas (1 cylinder) | 22.44 | m 3 |
Butane |
Liquid phase density | 0.60 | kg / l |
Liters in a cylinder | 42.00 | l |
Mass of gas in the cylinder | 25.24 | kg |
Gaseous density | 2,52 | kg / m 3 |
Volume occupied by 42 l of gas (1 cylinder) | 16.67 | m 3 |
Thus, how many liters of gas in a 50-liter cylinder, depends on what composition is pumped into it. Assuming that the cylinder is filled with one propane - 22.44 m 3 , butane - 16.67 m 3 . But since a mixture of these chemical compounds is used in everyday life, the indicator will be somewhere in between.
If we assume that propane and butane are in equal parts in the cylinder, then the answer to the question is, how much gas in a 50-liter cylinder (m3) is about 20.
Safety precautions when handling gas cylinders
- Never remove plates or labels from containers.
- Do not lift or move the container while holding the valve.
- Leaks should be determined using a soapy solution, not a lit match.
- Open the cylinder valve smoothly.
- Never heat the cylinder.
- Unauthorized transfer (overflow) of liquefied gas to other containers is prohibited.
