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]
Safety
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]
