“Shell Middle Distillate Synthesis process”如何翻 ...? shell middle distillate synthesis process 壳牌中间馏分合成工艺 ‘in essence, the shell mds technology is a three-stage process. in the first stage synthesis gas is obtained by partial oxidation of natural gas with pure oxygen in the shell gasification process (sgp) in the second stage, heavy paraffin synthesis (hps), the synthesis gas is converted into liquid hydrocarbons. in the third and final stage, the waxy syncrude is fractionated into high-quality products, a part of which is converted into middle distillates by means of the heavy paraffin conversion (hpc).’查看更多
