摘要
S Zorb装置主要增产汽油,以达到提质增效目的。S Zorb技术主要是在吸附剂和氢气作用下对催化裂化装置生产的催化汽油进行吸附脱硫生产清洁汽油产品。但再生器下料过滤器堵塞,吸附剂循环中断,影响产品质量,且不利于装置长周期平稳运行。针对问题对再生下料过滤器进行改造,实现在线清理的同时回收吸附剂,有效缩短了堵塞清理时间,保证装置平稳运行。
Increasing gasoline production is a key point for refineries to improve quality and efficiency.The S Zorb unit is mainly responsible for this task.The S Zorb patented technology is mainly used to adsorb and desulfurize the catalytic gasoline produced by the catalytic cracking unit to produce low sulfur clean gasoline products.However,the feeding filter of the regenerator was once blocked,and thus the adsorbent circulation was interrupted,which affected the product quality and the long-term stable operation of the unit.According to the cause of the problem,the operation department innovated the operation method,which changed the blanking nipple and conical filter,increased the adsorbent recovery process,and realized the adsorbent recovery during online cleaning,effectively shortend the blockage cleaning time,and ensured the smooth operation of the unit.
