Cooking gas

Cooking gas, or the so-called liquefied petroleum gas, or the so-called liquefied petroleum gas, is a mixture of gases that are stored under high pressure, to maintain their liquid state,[1] and are stored in cylinders, Or tanks,[2] made of heavy steel, and its boiling point ranges from -44 degrees Celsius, to 0 degrees Celsius,[1] and it was used in 1860 AD as a source of mobile fuel, and then its production and consumption spread for domestic and industrial use. Ethane and ethylene cooking gas, as well as volatile methanethiol.[3]



Cooking gas properties

Cooking gas is flammable and heavier than air, which stabilizes it in low areas or spots, such as drains or basements, which may pose a risk of suffocation, fire, or explosion. It is used in many uses, including : heating, cooking, industrial applications, vehicles, and fuels.[2]



Cooking gas production

Cooking gas is produced during the process of refining crude oil, or gas extracted during the processing of natural gas, producing mainly propane and butane, with small amounts of other gases, and then these gases are liquefied by storing them in Durable and strong tanks, with a pressure of about twenty times the atmospheric pressure, and the tanks in which gas is stored are very safe, and built-in shut-off valves to close the tank in case of leaks, with the addition of small amounts of ethanol, to add a strong smell, and this gas is characterized by its availability at high temperatures [4]



Exposure to cooking gas

Cooking gas can disperse into the environment while being used in equipment, appliances, or products that use cooking gas as fuel, such as a camping stove, or when it is stored, transported, or even disposed of, but when the products are used as recommended by The manufacturer may be exposed to this gas in small quantities.[5]



Cooking gas ingredients

Natural gas is one of the best types of fuel used in the world, but it is difficult to use it wherever it is when it is transported through pipes, whether in the operation of car engines or transporting it to rugged rural areas. To the liquefied state, which is easy for people to use and store in special containers and tanks, and from a chemical point of view, liquefied gas consists of a mixture of two combustible and non-toxic gases, namely propane and butane gas.


The chemical composition of both gases consists of hydrocarbons (a mixture of hydrogen molecules and atoms of hydrogen). Carbon), where propane comes in the formula (C3H8), meaning eight hydrogen atoms versus three carbon atoms, while butane gas has the chemical formula (C4H10), meaning ten hydrogen atoms versus four carbon atoms, and it is worth noting that liquefied gas is produced in varying proportions from Butane gas is called "isobutane".[6]



Cooking gas as fuel for cars

In some countries, the phenomenon of using cooking gas as fuel for cars is spreading in place of diesel and gasoline. What distinguishes the use of gas in cars is the following:[7]



Gas is like other types of fuel when it evaporates and ignites to give the energy required to move the car, but the difference lies in the storage method for gas, which needs thick and strong steel tanks (steel) with the installation of many safety valves on it, and tests conducted by a Dutch specialist have proven Gas-fueled cars remain safer than cars that run on petroleum fuels.


Ease of use

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



The importance of oil and gas in our lives

Oil (crude oil) is characterized by its high density and high flammability, and it is a yellowish-black oil, and it was first discovered in the form of leaking oil from among the rocks on the surface of the earth.


The second part of the name (oleum) means oil, and the entire composition means (rock oil) with a hydrocarbon chemical composition, and it is an organic compound that contains 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 one of the natural energy sources in our lives that we humans use in operating cars, buses, planes, ships and many other means of transportation, and other aspects of the importance of oil and gas is their use as a source in home heating, just like electricity. In many industries such as plastic, material, wax, fertilizer, car oils, mechanical machinery and many other industries.[8]
