Introduction of Liquefied Petroleum Gas
LPG is gaseous at room temperature and pressure. Internationally, LPG is usually pure gas in the form of pure propane and pure butane, which is transported by cryogenic liquefaction in refrigerated tanks; domestically, LPG is mainly a mixture of gas, propane-butane, and olefin, which is transported by liquefaction in pressure tanks.
The main routes for LPG are fuels and chemical raw materials. In the field of fuel, LPG has high calorific value and is clean and environmentally friendly, mainly consumed by catering, civil and industrial and commercial industries; its calorific value is about 24,000 kcal per cubic metre, which is three times of that of natural gas; in the field of chemical industry, it is used as a partial substitute for naphtha, and for the production of petrol additives and propylene.
