Liquefied petroleum gas is a synthetic universal mixture of propane, butane and a small amount of unsaturated hydrocarbons obtained during oil production or its subsequent processing. In principle, such a mixture is a by-product of oil production, so to speak, a nice bonus. During the development of "black gold" deposits, associated petroleum gas (APG) is released, which is then processed into liquefied gas at enterprises of the corresponding profile.
For each ton of crude oil, there are from fifty to five hundred cubic meters of APG, which is sent along with the main product to the refinery, where it is compressed (liquefied). Liquefied gas is obtained from NGL (broad fraction of light hydrocarbons), which is released from APG. This mixture is then compressed under high pressure without changing the temperature.
Liquefied gas for industrial applications andheating of various buildings, is stored in special ground or underground tanks - gas holders. In terms of the amount of energy released, fuel from hydrocarbon components is second only to mainstream natural gas.
Liquefied hydrocarbons are an important raw material for the petrochemical industry. For the manufacture of various products, such gases are subjected to the process of pyrolysis, which takes place at ultrahigh temperatures. As a result, compounds of olefins (ethylene, propylene, etc.) are formed - acyclic unsaturated hydrocarbons with one double bond between atoms. Then these complex compounds are converted into various types of polymers and plastics (polyethylene, polypropylene and others) through the polymerization process. Thus, the packaging containers we use daily, disposable tableware and various everyday items were once liquefied gases.
But the main purpose of such gaseous mixtures is different. In the light of some problems in the field of energy against the background of the general economic crisis and the emphasized concern of the world community about the environmental situation on the planet, liquefied gas is becoming extremely relevant and may soon take a leading position as a motor fuel. Environmentally friendly fuel, which is important.
Already today, the global fleet of vehicles running on liquefied hydrocarbons has more than 20 million vehicles. Also LPGIt is widely used for heating residential buildings and huge buildings of industrial enterprises, for drying, welding and cutting metals. In addition, it occupies a fairly strong position in the field of agriculture, where it is used to burn out weeds and pests.
The excellent environmental, economic and thermotechnical qualities that liquefied petroleum gas fully possesses make it an ideal energy carrier for the present and future. It is capable of solving the energy and environmental problems of mankind for many years.

LNG tanker for the transport of liquefied gas
Reserves of natural gas in the world are huge, but most of the deposits are located in hard-to-reach places, remote from industrial areas. This is not so bad - a pipeline can be laid on land or on the seabed. And for transportation across the ocean, the gas is converted into a liquid state. At the same time, the volume is reduced by almost six hundred times, which makes it possible to use not only pipelines, but also LNG tankers of a special design for gas transportation
Solid fuel is Types, characteristics and production of solid fuel
Non-fossil solid fuel based on wood and industrial waste - affordable and efficient fuel. The modern market offers a wide range of solid fuels, differing in efficiency and characteristics
Diesel fuel: GOST 305-82. Characteristics of diesel fuel according to GOST
GOST 305-82 is outdated and replaced, but the new document, which came into force at the beginning of 2015, did not change the requirements for diesel fuel for high-speed engines so noticeably. Maybe someday such fuel will be banned for use altogether, but today it is still used both in power plants and on diesel locomotives, heavy military equipment and trucks, the fleet of which has been preserved since the days of the Soviet Union due to its versatility and cheapness
Diesel fuel is Types, grades, brands, classes of diesel fuel
Diesel fuel, which until recently was used in various industries, is becoming more in demand, as more passenger cars are produced with diesel engines, and owners of private vehicles have to understand the characteristics of this fuel
Fuel consumption of an aircraft: types, characteristics, displacement, amount of fuel and refueling
Fuel consumption of an aircraft is one of the important indicators of the efficient operation of mechanisms. Each model consumes its own amount, tankers calculate this parameter so that the airliner is not loaded with excess weight. Various factors are considered before allowing a departure: flight range, availability of alternate airfields, weather conditions of the route
