Abstract: In order to fully tap the potential of energy saving and emission reduction in the semi-regenerative catalytic reforming unit, the heat balance of the heat carrier system of the 250 kt/a semi-regenerative catalytic reforming unit of Qingdao Petrochemical Co., Ltd. was analyzed, and the heat transfer flow and operating parameters of the evaporator, fractionator and stabilizer were optimized. The results show that the heat carrier system of the catalytic reforming unit can stop using the heat carrier furnace. It can save 321.14 (MW.h)/a of electricity consumption and 621.96 t/a of fuel gas consumption, reduce 1 750 t/a of CO2 emission, and increase the economic benefits by about 2 732 200 Yuan/a.
