乙烯装置碳二前加氢催化剂运行探讨

DISCUSSION ON THE OPERATION OF C_2 FRONT-END HYDROGENATION CATALYST IN ETHYLENE PLANT

上海石化烯烃部700kt/a乙烯装置新区采用碳二前加氢工艺流程,在将近7年的生产过程中先后采用了进口G-83C型和国产BC-H-21B型前加氢催化剂。通过对其工艺运行性能的不断摸索和改进,使得进口催化剂连续稳定运行了5年又3个月,随后投用的国产催化剂各项工艺运行指标也表现良好。

C2 front-end hydrogenation process is adopted in the new section of the 700 kt/a ethylene plant at SINOPEC Shanghai Petrochemical Co.,Ltd.,and imported G-83C front-end hydrogenation catalyst and homemade BC-H-21B front-end hydrogenation catalyst was successively used during its 7 years of operation.The imported catalyst was operated continuously and stably for 5 years and 3 months through continuous exploration and improvement of its process performance,and the homemade catalyst also achieved good process performance.
