摘要
为了满足低凝柴油的市场需求,提高装置利用率,中石油克拉玛依石化有限责任公司对利用现有润滑油加氢处理装置增产-35号低凝柴油的方案进行了详细的可行性研究。工业试生产及标定结果表明,以柴油加氢改质装置的加氢重柴油为原料,经润滑油加氢处理装置加工后,柴油的凝点可由-22℃最低降至-58℃,冷滤点可由-1℃最低降至-32℃,油品的低温性质得到明显改善。经济核算结果表明,采用该方案后,该装置可增产低凝柴油54 kt/a,预计增加经济效益1210万元a。
In order to meet the market demand for low-pour point diesel and to improve the utilization ratio of the unit,the feasibility of increasing the production of low pour point diesel No.-35 by using the existing 0.15 Mt/a lube base oil hydrotreating unit was studied in PetroChina Karamay Petrochemical Co.,Ltd.The results of commercial production and calibration show that the freezing point of product diesel is decreased from-22℃to-58℃,and the cold filter plugging point is decreased from-1℃to-32℃,the cold flow properties of the product diesel are significantly improved.The economic accounting results show that the unit can produce 54 kt of low pour point diesel in the whole year,and the economic benefit is increased by 12.1 million Yuan/a.
