加氢裂化尾油在倒梯台裂解炉上的工业应用

随着中国石化上海石油化工股份有限公司炼化部2号乙烯装置的改扩建项目投产,乙烯裂解原料的缺口也将相应增大。为满足企业生产物料平衡的需求,拓宽并优化1号乙烯装置裂解原料,在1号乙烯装置F-101倒梯台裂解炉上进行加工加氢裂化尾油的试验。由于加氢裂化尾油组分重、干点高,加工试验的主要目的是验证加氢裂化尾油在1号乙烯装置倒梯台炉上裂解的可行性,包括加氢裂化尾油裂解性能,裂解炉运行周期。

Industrial Application of Hydrocracked Tail Oil in Inverted Trapezoidal Cracking Furnace

After the Ethylene Plant of Jinshan Petro- chemical Company was revamped and put into opera- tion,the ethylene cracking feedstock gap of supply and demand was accordingly increased.In order to meet the demand of material balance and optimize the cracking feedstock for No.1 Ethylene Plant,an experiment was carried out on the F-101 inverted trapezoidal cracking furnace to process hydrocracked tail oil.Because the hydrocracked tail oil consists of heavy component and has high dry point,the main purpose of the experiment was to validate the feasibility analysis of cracking hydro- cracked tail oil in inverted trapezoidal cracking furnace, including the cracking performance of hydrocracked tail oil and the operation cycle of cracking furnace.
