加氢裂化尾油的综合利用

加氢裂化尾油具有性能优良、饱和烃含量高，芳香烃含量、硫含量和氮含量低等特点，不仅能做乙烯裂解原料，同时也是优质的润滑油基础油原料，可以生产变压器油、内燃机油和液压油等产品，同时还能得到柴油等副产品，综合利用价值显著。通过采用减压蒸馏、溶剂脱蜡和白土补充精制等工艺，对辽阳石化公司生产的两批不同性质的加氢裂化尾油进行实验室研究，考察了辽化加氢裂化尾油作为润滑油基础油适用情况。实验表明，两批加氢尾油经过加工分别可以得到收率为15.3％的HVI100基础油，34.5％的HVI150基础油和20.4％HVI400基础油，以及柴油和变压器油等产品，具有综合利用价值。

THE COMPREHENSIVE UTILIZATION OF HYDROGENARATION CRACKING TAIL OIL

Hydrogenation cracking tail oil is of excellent performance, with high saturated hydrocarbon content, low sulfer and nitrogen content, it can be ethane cracking substance, also good quality basic oil raw material of lubricating oil, it can also be used to produce transformer oil, combustion engine oil and hydraulic oil etc., meanwhile, the by product of diesel can be obtained. Hydrogenation cracking tail oil from Liaoyang petrochemical Corp. is researched in Lab, the utilization of the hydrogenation cracking tail oil as basic oil of lubricating oil is investigated through the technique of vacuum distillation, solvent dewax and replenishment refinement. Research indicates that 15.3% HVI100 basic oil recovery, 35.4% HVI150 basic oil, 20.4% HVI 400 basic oil, diesel and transformer oil, can be obtained through hydrogenation cracking tail oil.
