OPTIMIZATION AND ENERGY SAVING ANALYSIS ON THERMAL CARRIER SYSTEM OF SEMI-REGENERATIVE CATALYTIC REFORMING UNIT

Abstract

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.

Key words: catalytic reforming, heat carrier, heat carrier furnace, four in one heating furnace, energy saving, emission reduction, efficiency improvement
