BingDing alkanes liquefied petroleum gas (LPG)

LPG is to point to by high pressure or low temperature of liquefied petroleum gas (LPG), hereinafter referred to as "liquefied petroleum gas (LPG)" or "gas".Its composition is propane, butane, isobutane and small amounts of ethane, greater than 5 organic carbon compounds, unsaturated hydrocarbons, etc.With flammable and explosive of LPG, gasification, thermal expansion, stranded, charged, corrosive and suffocation, etc.

LPG (C3H8), mainly by propane butane (C4H10), some of the LPG contains propylene (C3H6) and butene (C4H8).LPG generally acquired from oil and gas, refinery liquefied petroleum gas (LPG) and ethylene.Compared with other fuels, LPG has the following unique advantages.

Less pollution

LPG is made up of C3 (carbon), C4 hydrocarbons composed of carbon (4), can full burning, no dust.Application in the modern city, can greatly reduce the pollution with coal, wood for fuel.

High calorific value

2 times the same weight of LPG calorific value of coal, liquid heat for 45 ~ 185 45 980 kj/kg.

Easy to transport

LPG is gas under atmospheric pressure, under the certain pressure or frozen to a certain temperature can be liquefied to liquid, can use the train (or car) and LPG ship on land and water transportation.

The pressure stability

LPG pipeline users kitchen before pressure constant, easy to use.

Storage is simple, flexible supply

With city gas production, storage and supply situation, LPG storage device is simpler, QiZhan use LPG storage tank to store, and can be installed in the cylinder for users to use, also can through the QiZhan and supply pipe network, the pipeline gas supply;Even available on the namesake fizzy butane gas, being used as fuel in the hot pot on table, its usage is convenient.

Since the LPG has these advantages, is widely used for industrial, commercial and civil fuel.At the same time, its chemical composition determines the LPG is also a very useful chemical raw materials, and therefore is widely used in the production of various kinds of chemical products.

Gas liquefaction oil is about 1.5 times heavier than air, the gas mixture of air explosive range is 1.7% ~ 9.7%, fire or explosion.So when using must prevent leakage, not sloppy, so as not to cause harm.
