提高S Zorb装置加工量的措施

 分析了中国石化济南分公司900 kt/a S Zorb装置自开工以来加工量低于设计值的主要原因。通过采取增加原料进装置过滤器、对原料换热器进行抽芯清洗、提高催化裂化装置提升管出口温度、提高催化裂化汽油直供温度、调整吸附剂循环再生频次、加热炉燃料改用重瓦斯、降低反应温度和采用高纯度氢气等措施，在生产的汽油产品满足国III排放标准要求的前提下，S Zorb装置的加工量提高了11 t/h左右。

MEASURES FOR UPGRADING THE PROCESSING CAPACITY OF S ZORB UNIT

The main causes of lower processing capacity than the design value of the 900 kt/a S Zorb unit in SINOPEC Jinan Company were analyzed and counter measures were discussed. Since adopting measures, such as adding another feed filter, cleaning heat exchanger of feed, increase the riser outlet temperature of FCC unit, increase the direct feed supply temperature from FCC unit to S Zorb unit, adjusting the cycle rate of sorbent and frequency of regeneration, using heavy gas as fuel of heating furnace, reducing the reaction temperature and using high-purity hydrogen, the processing capacity of said S Zorb unit has an increment of about 11 t/h and the gasoline product also well meets the requirement of National Emission Standard III.
