摘要/Abstract

摘要： 根据中国石化青岛炼油化工有限责任公司2.0 Mt/a加氢裂化装置的工业生产数据，结合装置设计数据，对该装置的操作弹性进行分析界定。认为该装置适用的原料范围为馏程233～570 ℃、密度（20℃）850～931 kg/m3、硫质量分数0.8%～2.5%；反应系统操作参数范围为进料量150～318 t/h、精制反应温度332～371 ℃、裂化反应温度351～384 ℃、氢分压12.3～15.2 MPa；在增产喷气燃料方案中，喷气燃料收率可达46.01%，在增产柴油方案中，柴油收率可达60.49%，在增产尾油方案中，尾油收率可达54.88%。对该装置不同工况下的经济效益进行测算，认为在当前定价体系下，增产喷气燃料方案为经济效益最佳的方案。

Abstract: Based on the industrial operation data and the design data of 2.0 Mt/a hydrocracking unit in Qingdao Refining & Chemical Co. Ltd, SINOPEC, the operation flexibility of the unit was defined. The feedstock (VGO) properties are limited in the ranges: boiling point of 233-570 ℃，density of 850-931 kg/m3(20 ℃)，and sulfur content of 0.8%-2.5% and the operation parameters are as follows: throughput of 150-318 t/h, hydrorefining temperature 330-414 ℃, and cracking temperature 340-429 ℃. Under those constraint conditions, the yields of kerosene, diesel and tail-oil can reach 46.01%, 60.49% and 54.88% for kerosene, diesel and tail-oil solutions, respectively. The economic profit analysis of the solutions indicates that under the current pricing system, the kerosene solution is the best one.
