什么叫轻烃 | 2011-10-29 17:23:00

什么叫轻烃

    石油是原油、天然气的统称。原油只是指以液态形式天然形成的比较重的烃类组分，天然气指的是以气态形式存在的比较轻的烃类组分。而轻烃则是把原油或者天然气进行初加工，在原油或者天然气中分离出来的C7～C9的组分，其中的C7、C9百分含量为最高，占轻烃总重量的50％左右。
    我们把可不经分离直接用作热烈解制轻质烯烃的原料称之为轻烃。轻烃在化工业中有广泛的用途，是乙烯、塑料等加工业不可缺少的原料。
    轻烃是一种无色透明的液体，组分较轻，易挥发，大量的挥发气可使人窒息。轻烃易燃易爆，给天然气加工业带来许多困难。在轻烃的储存、输送及生产过程中，要防止泄露和静电的产生。
