液化石油气罐

　　液化石油气是以C3、C4为主要成分的烃类混合物。其临界压力较低，临界温度较高，沸点较低，因而液化石油气在常温常压下呈气态。为了便于储存和输送，只需把它升高压力或降低温度就可成为液体。

　　液化石油气作为一种化工基础原料和生产、生活用燃料，受到人们的重视。在化工生产方面，液化石油气经过分离得到乙烯、丙烯、丁烯、丁二烯等，用来生产合成塑料、合成橡胶、合成纤维及生产医药、炸药、染料等产品。用液化石油气作燃料，由于其热值高，无烟尘，无炭渣，操作使用方便，已广泛用于替代汽油，作汽车燃料和民用生活燃料。此外，液化石油气还用于切割金属，用于农产品的烘烤和工业窑炉的焙烧等。

　　Liquefied Petroleum Gas Tank

　　Liquefied petroleum gas is a kind of mixture of hydrocarbons with the main components C3 and C4. It has a low critical pressure, high critical temperature and low boiling point, so liquefied petroleum gas is in a state of gas under atmospheric temperature and atmospheric pressure. In order to store and transport it, raise its pressure or decrease the temperature to change it into liquid.

　　As a kind of chemical material and fuel used in manufacturing and life, liquefied petroleum gas has been paid much attention to. In production of chemical industry, ethene, propene, butane and butadiene can be separated from liquefied petroleum gas which can be used to produce synthetic plastics, synthetic rubber, synthetic fiber and medicine, explosives, dyestuff and other products. As a kind of fuel, liquefied petroleum gas has been widely used to replace the gasoline for its high heat value, no smog and dust and no carbonresidue. Besides, liquefied petroleum gas is also used to cut metals, bake agricultural products and roast industrial furnace.
