摘要
重油高效催化裂解(RTC)技术是以劣质重油为原料的催化裂解多产低碳烯烃的新工艺,在“油转化”和“双碳”的大背景下,对炼油行业产品结构调整和低碳转型发展有着重要作用。对已投产的一套3.0 Mt/a RTC装置的运行数据和某企业两套在建的RTC装置的现状进行深入分析,建议RTC装置的反应压力设定在130~160 kPa,并使用干气作为稀释蒸汽,注入稀释蒸汽的比例应控制在20%以下;应根据下游装置利用C 4资源的经济性,合理设置第二提升管的原料类型和回炼量。
Residue to chemicals(RTC)technology is a novel technology that uses inferior heavy oil as raw material to produce more light olefins.In the context of“oil conversion”and“dual carbon”,RTC plays an important role in the adjustment of product structure and low-carbon transformation and development in the refining industry.An in-depth analysis was conducted on the operational data of a 3.0 Mt/a RTC unit that has already been put into production and the current situation of two RTC units under construction.It is recommended to set the reaction pressure of the RTC unit at 130-160 kPa.Using dry gas as dilution steam,and the proportion of injected dilution steam should be controled within 20%.The raw material type and recycling capacity of the second riser should be reasonably set based on the economic efficiency of downstream equipment utilizing C 4 resources.
