What is LPG OR cooking gas

Cooking gas or LPG

LPG

Cooking gas, or LPG gas (Liquefied Petroleum Gas), is a mixture of gases that are stored under high pressure to maintain their liquid state. It was used in 1860 as a source of mobile fuel and then produced and consumed for domestic and industrial use. Cooking gas of ethane and ethylene, as well as volatile methanethiol gas.

Characteristics of LPG

Cooking gas is flammable and heavier than air, which stabilizes it in areas or low spots, such as sinks or basements, which may pose a risk of suffocation, fire, or explosion. : Heating, cooking, industrial applications, vehicles, fuel.

Cooking gas production

Cooking gas during the refining process of crude oil, or gas extracted during natural gas processing, is produced mainly by propane and butane, with small amounts of other gases, and then liquefied by storing them in Durable and strong tanks, with pressure of about twenty times the atmospheric pressure, and the tanks in which the gas is kept very safe, and integrated shut-off valves to close the tank in case of leaks, with the addition of small amounts of ethanol, to add strong odor, and this gas is available at high temperatures .

Exposure to cooking gas

LPG can spread to the environment while used in equipment, appliances, or products that use cooking gas as fuel, such as a camping stove, when it is stored, transported, or even disposed of, but when using products as recommended by The manufacturer may be exposed to this gas in small quantities.

Cooking gas components

Natural gas is one of the best fuels used in the world, but it is difficult to use wherever it is transported through pipelines, whether in the operation of motor engines or transported to rugged rural areas, and to resolve this issue resorted to the idea of ​​converting gas transported through pipelines (in the case of gas) Chemical liquefaction gas consists of a mixture of two combustible and non-toxic gases, propane and butane.

The chemical composition of both gases consists of hydrocarbons. (A mixture of hydrogen molecules and carbon atoms), where propane comes in the formula (C3H8), ie, eight hydrogen atoms versus three carbon atoms, while butane gas is a chemical formula (C4H10) or ten atoms of hydrogen versus four atoms of carbon, Liquefied gas is produced in varying proportions of butane gas called ” isobutane “.  

Cooking gas as fuel for cars

The use of LPG as a fuel for cars rather than diesel and gasoline is common in some countries.

Security

The gas is like other fuels when it evaporates and ignites to give the energy required to move the car, but the difference lies in the method of storage of gas, which requires thick and strong tanks of stainless steel (steel) with the installation of several safety valves on it, has been proved by tests conducted by a competent Dutch Gas car accidents remain safer than cars running on fuel oil. 

Ease of use

According to specialists, most of the engines powered by oil derivatives can be converted by adding an additional combustion system through the liquefied gas system, which means that the vehicle will operate in the presence of two combustion systems.

The importance of oil and gas in our lives

The oil (crude oil) is characterized by high density and high flammability, a yellowish-black oil, was the first discovery in the form of leached oil from the rocks on the surface of the earth, and therefore came from the Latin word (petra) which means the word rock.

The second part of the name (oleum) means oil, and the composition in its entirety means (rock oil) with the chemical composition of hydrocarbons, an organic compound containing only two elements, carbon, and hydrogen, in addition to that it comes out to the surface of the earth in the form of a mixture of natural gas, diesel, kerosene, and asphalt.

The importance of oil and its derivatives as a source of energy Sales in our lives that we humans use in the operation of cars, buses, aircraft, ships and many other modes of transport, and other aspects of the importance of oil and gas used as a source in domestic heating, such as electricity, in addition, the chemical formulations of oil are involved in many industries such as plastic, material, wax and fertilizer And automobile oils, mechanical machines and many other industries.

Inhalation Damage LPG

LPG is a liquefied gas, which is like water does not taste and color and does not smell, but it is flammable and this is where it needs one spark, which helps in full ignition, and is also very explosive as it explodes because of this step and there must be a structure Pungent smell and this is even attention to this danger, so the smell, which smells a chemical smell and not the smell of gas.

This gas is not only the highest, but it is on the ground and is at a distance of 40 cm and is a suffocating gas and not toxic gas, which is fast and very widespread, where a cup of butane gas is equal to 272 cups gas stream and that wood and plastic materials imbibe this gas is Compressed and gas hazards.

The danger of LPG

Fire hazards

This is when there is a fire, the gas must be separated by the safety of electricity. This is where the gas switch in the tube is controlled and closed by all available means because without control of the tube can not control the gas fire and is notified to the civil defense and help neighbors to control the fire.

Leakage hazards

And that the leak of gas is one of the most serious problems that lead to the fire, so it must be human when a gas leak to be quiet and open the door of the house very quietly and this so that no friction occurs in the ground, which results in a spark which leads to disaster as well as not Opens the door quickly and this so as to avoid the pressure of air, which produces a static electric spark and maybe strongly spark ordinary electricity and must not touch the electricity permanently.

Either lighting or ventilation and also do not walk quickly or lock gas for fear that the gas is automatic and come out spark and disaster occurs Is opened The doors and windows and the work of ventilation is important and patience to get rid of the smell of gas completely and then behave as if there are nothing and a crescent during this period and must not ignite the fire or electricity.
