脱氮保硫——加工我国基础油的方针

DENITROGENATION AND SULPHUR CONSERVATION IS THE ROUTE OF PROCESSING DOMESTIC BASE STOCK

针对含氮高、含硫低的现实，在加工我国原油时，应当脱氮保硫，即尽量保有天然抑制组分和去除氧化组分。本工作提出的Ｎ、Ｓ平衡值不失为直控生产的有效指标。本文从基础油加工、精制深度的控制。

According to the high nitrogen and low sulphur content,relatively keeping sulphur and removing nitrogen from the distillates of base stock are suitable for processing domestic crude oils,i.e. preserving the natural inhibitor and removing the oxidation component as much as possible.Nitrogen\sulphur equilibrium constant value presented in this paper can get to effective target of the product direct refined .The above were described from base oil process and refining depth control ,and so on.
