History of liquefied gas ( LPG )

LPG

The term liquefied gas (LPG) refers to gas-like liquids that are obtained from both natural gas and crude oil refining processes.

Liquid gas consists of two products, propane and butane.

Liquefied Petroleum Gas (LPG) is the main combination of two hydrocarbons butane (C4H10) (which includes isobutane and normal butane) and propane (C3H8). Propylene and butylene are also available in this composition.
LPG in the refinery is a by-product of natural gas purification and crude oil refining.

This gas turns into a liquid at a temperature of 21 degrees Celsius under a maximum pressure of 8 kg/cm2. And at the time of production, it lacks color, smell, and even taste, which sulfur compounds called mercaptan (which includes ethyl mercaptan and methyl mercaptan) are added to it in the refinery for more safety.

Domestic use and small industries, industrial use, standard capacities of industrial liquefied gas tanks, LPG uses, related searches of LPG content sources.

These two mentioned gases are in the form of gas under normal conditions of the environment (in terms of pressure and temperature) , but when they are placed under pressure or under refrigeration conditions for storage or transportation , they become liquid.

This dual and special feature has made liquefied gas to be the last hydrocarbon whose business has been developed.

First commercial production of LPG

Its first commercial production took place in the 1920s and its first global trade in the 1950s.

Sea trade of liquefied gas, which was less than 1 million tons in 1960, reached 17 million tons in 1980 and 48 million tons in 2000.

The LPG industry has seen a fair share of ups and downs over the past fifty years. Many of its actors left the scene, but many who continued remained.

Production of an industry

About 50 years after oil was discovered and exploited in the Appalachian oil fields located in western Pennsylvania, the story of LPG also began in this land.

Along with oil, gas is also extracted. At the beginning of the 20th century, the market and demand for gas had also developed, but before the gas could enter the pipelines, the accompanying liquids had to be separated.

The crude liquids recovered by condensing the wet gas (a mixture of propane, butane, pentane, and heavier materials) were called wild gasoline or oilfield gasoline.

As its name suggests, this product became one of the first fuels used in the transportation sector due to the characteristics of light oil cuts.

Also, this liquid contained considerable amounts of light and highly volatile compounds, and for this reason, it could not be used or transferred in the same simple way as the original. Instead, the liquid was exposed to air in open tanks to evaporate its very light compounds.

At that time, the oil industry did not have a proper measurement system to determine the vapor pressure.

As a result, the operation of storing or transporting this unstable fuel was accompanied by many explosions and accidents.

In the Asalouye database, it is mentioned about the advantages and disadvantages of LPG that the advantages of using LPG in gas-powered cars are:

  • Due to the gas mode, the engine of the LPG burning car starts easily even in cold weather.
  • LPG fuel systems are covered and their evaporative waste can be ignored.
  • It is easy to transport and it is convenient for consumers to refuel it, unlike LNG and CNG.
  • LPG burning vehicles do not need to use a catalyst to standardize exhaust gases.
  • The toxic particles resulting from its combustion are insignificant compared to gasoline and diesel.
  • Compared to other fuels, any increase in demand for LPG can be met from natural gas sources as well as crude oil refining sources.
  • PAH and aldehyde emissions from LPG combustion are negligible compared to fossil fuel vehicles.
  • If we examine these advantages carefully and in comparison with CNG, we will see that all the reasons except for the third reason are also among the advantages of CNG, while considering the wide network of city gas pipelines, the third reason is automatically resolved in comparison with CNG.

Kian Group

Kian Group International Company is the largest supplier and exporter of petroleum products in Turkey, which with the cooperation of its representative in Iran , Kian Petroleum Company, is able to supply various oil, mineral and steel products directly from the doors of Iranian factories.

Comparison of LPG gas with gasoline

Comparing gasoline and CNG, it should be said that this gas has a high octane, burns cleanly, can be measured, and usually produces low emissions. Vehicles with LPG fuel have less pollution than gasoline and diesel vehicles.

Greenhouse gases and nitrogen oxides resulting from LPG combustion in vehicles are less than gasoline and diesel. Also, in the production, transportation and refueling stage, due to the gaseous nature of LPG, unlike gasoline and its additives such as MTBE, it does not pollute groundwater.

Uses of LPG

This gas is used in many places where it is not possible to use other sources of fuel because it is easily transportable.

  1. Houses for gas stoves and heating devices
  2. Factories for fueling furnaces and burners (and in some of them for secondary fuel)
  3. Industrial and commercial kitchens
  4. Ignition system of gas turbines in combined cycle power plants
  5. Second fuel for cars

Kian International Group Company is the largest exporter of LPG in Iran and the representative of Kian Petroleum Company in Iran to supply and supply all products of the Energy Exchange and Iran Commodity Exchange for various uses of industries and by selling products of the Energy Exchange and Iran. Commodity Exchange in Ring International, while meeting the needs of customers in foreign markets, has provided the possibility of offering a variety of steel products at competitive prices to domestic and foreign markets, which shows the high potential of the company in the field of steel.
