苏丹减压渣油对丁烷脱沥青装置开工的影响及分析

Analysis on the Impact of Sudan Vacuum Residue to Start-up of Butane Deasphalting Unit

苏丹减压渣油具有凝点、蜡含量、酸值和金属含量高等特点,尤其是重金属元素镍、钒、铁、钠含量较高,是一种热稳定性较差的渣油。该减压渣油经丁烷脱沥青装置加工处理后,可降低其酸含量、金属含量、黏度及残炭值,从而为催化裂化装置提供更加优质的原料,创造更大的效益。

Vacuum residue of Sudan crude oil has the characteristics of high freezing point, wax content, acid value and metal content, in particular, nickel, the thermal stability of residue is inferior. Butane deasphalting vanadium, iron, sodium content is high, and viscosity and residual carbon content and provide more excellent obtain more economic benefits. unit could reduce the metal content, lower raw materials to the catalytic unit, thereby,
