催化裂化装置应用MFP技术的工业试验

INDUSTRIAL TEST OF MFP TECHNOLOGY IN FCC UNIT

介绍了多产丙烯和低硫燃料油组分的催化裂化与加氢脱硫(MFP)技术在催化裂化装置的改造内容、工业试验以及工业应用。以MIP-CGP工艺为空白标定,对比了在专用催化剂占系统藏量50%和80%时MFP工艺操作条件和产品分布的变化。结果表明,采用MFP技术后,产物氢分布改善,液化气中丙烯和异丁烯含量大幅增加,低碳烯烃收率和选择性得到提高,并且维持了干气量和生焦量的稳定。催化裂化技术从追求高转化率向高选择性的转变,实现了碳氢资源高效利用;同时可以根据市场需求变化灵活调整生产方案,实现经济效益的最大化。

The catalytic cracking and hydrodesulfurization technology for producing more propylene and low sulfur fuel oil components in FCC unit was introduced,including revamping,industrial test and industrial application,so as to flexibly adjust the production plan to meet market demand.The MIP-CGP process was used as blank calibration,and the changes of Marine Fuel and Propylene(MFP)process operating conditions and product distribution were compared when the special catalyst accounted for 50%and 80%of the system storage.The results show that hydrogen distribution is improved,the propylene and isobutene content in LPG is greatly increased,the yield and selection of low-carbon olefins are improved,and dry gas and coke production are kept stable.FCC technology has been changed from high conversion rate to high selectivity,which can realize the efficient utilization of hydrocarbon resources,and can adjust production plan flexibly according to the change of market demand to realize the maximization of economic benefit.
