摘要
沈阳化工集团沈阳石蜡化工有限公司建设了世界上首套500 kt/a重油催化热裂解(CPP)制烯烃工业装置,于2009年6月建成并投入运行。该装置以石蜡基常压渣油为原料,以生产乙烯、丙烯等低碳烯烃为主要目的产品,副产高含轻芳烃的裂解石脑油。工业标定结果表明,以大庆常压渣油为原料,在兼顾乙烯和丙烯的操作模式下,在反应温度610℃、乙烷/丙烷没有回炼的条件下,乙烯和丙烯产率分别达到14.84%和22.21%,裂解石脑油中芳烃的质量分数达到82.46%,符合设计目标。该装置的成功运转开辟了一条重质原料生产低碳烯烃和轻芳烃的新工艺路线,实现了炼油与化工的一体化。
The first commercial unit worldwide of heavy feed catalytic pyrolysis process （CPP） was set up and put into operation in June 2009 at Shenyang Chemical Group Shenyang Paraffin and Chemical Company with a capacity of 500 kt/a. This unit is designed for processing paraffinic atmospheric residue feedstock to obtain main products, ethylene and propylene, with cracked naphtha having high light aro- matics as by-product. The results of performance test show that using Daqing atmospheric residue feed- stock, under ethylene plus propylene operation mode, at a reaction temperature of 610℃ and without recycle of ethane and propane, the yields of ethylene and propylene reach 14.84% and 22.21%, respec- tively;the aromatics mass fraction of cracked naphtha is 82.46%, which all well meet the design tar- gets. The successful running of this unit opens a novel light olefins and aromatics production route from heavy feedstock, which is also a good example of refining and petrochemical integration.
