生产这种不饱和烃类最重要的路线是靠蒸汽裂解，主要以石油气体和石脑油作原料。

The most important route to produce these unsaturated hydrocarbons is by steam cracking, using principally petroleum gases or naphtha as feedstock.

利用初顶油气、稳定石脑油等低温余热加热除盐水建立热水站，在节汽、节电等方面取得了较好的效果。

A hot water station is set up to heat up desalted water, using the low temperature topping gas oil and stabilized naphtha, thus, good results are obtained in the aspects of steam and power saving.
