摘要
青海格尔木炼油厂10万t/a临氢降凝装置,由于原料系青海原油的高含蜡、高含氮直馏常三线油,因此该装置采用加氢精制—加氢脱蜡两段工艺生产低硫(≤0.05%)、低凝点(冷滤点符合-35号柴油规格)的合格柴油产品。该工艺有效地缓和了柴油临氢降凝的反应条件,对提高柴油产品收率,延长催化剂使用周期及提高柴油产品的质量极为有利。该工艺对原料适应性好,扩大了生产低凝。
Abstract The 1×10 5 t/a hydrodewaxing unit of Germu refinery in Qinghai province, as feedstock is straight run cut three atmospheric oil with high content of wax and nitrogen generated from crude oil of Qinhai Oilfield, adopts two process steps including hydrofining and hydrodewax to produce the qualified diesel with low content of sulfur (≤0.05%) and low pour point (cold filtration point comply with No.35 diesel). The process improves the reaction condition of hydrodewaxing of diesel, which is very helpful for increasing share of diesel product, and prolonging the life circle of catalyst and improving the quality of diesel product. The process has a good adaptability for crude material and enlarges the feedstock scope of producing diesel with low pour point and low sulfur.
