1.2 Mt/a S Zorb装置生产超低硫清洁汽油运行概况

摘要

介绍了中国石化北京燕山分公司S Zorb装置生产满足京V标准的汽油的运行情况.通过对装置加工负荷、原料硫含量进行控制,对吸附剂的反应-再生循环参数进行优化,可以连续稳定地生产硫质量分数低于8 μg/g的满足京V排放标准要求的汽油调合组分.同时也对影响装置稳定生产的主要因素进行了分析,提出了相应的对策.%Sulfur content in gasoline is limited blow 10 μg/g by newly executive legislation in Beijing.The S Zorb technology has been used for desulfurization of FCC gasoline in Yanshan Refinery.Measures such as controlling the load of the unit,sulfur content in feed and activities of sorbent are adopted to ensure the stable operation.Problems occurred in operation and countermeasures and improvement are also discussed in detail and the results indicate that these measures are useful for long and stable running of S Zorb unit.
