蒸汽裂解工艺重质原料优质化

QUALITY OPTIMIZATION OF HEAVY FEEDSTOCK FOR STEAM CRACKING PROCESS

长期以来轻柴油都是我国重要的裂解原料,随着柴汽比的不断提高,如何选择替代原料成为我国石化行业一项重要任务。我国许多乙烯装置都有使用减压蜡油(VGO或LVGO)的工业经验,减压蜡油经过预处理可以成为与轻柴油裂解性能相当的替代原料。

Light diesel has always been an important cracking stock in China.With increasingly higher diesel to gasoline ratio,selecting a substitute feedstock has become an important task for Chinese petrochemical industry.VGO/LVGO has been used as feedstock for many domestic ethylene plants.Pretreated VGO/LV-GO,which is equivalent to light diesel in cracking performance,can be used as a substitute feedstock for light diesel.
