摘　　要：采用新型立体传质塔板对燕山石化炼油事业部的8×105t/年减压渣油催化裂化装置的再吸收塔进行技术改造,新设计塔径为　1200mm,30层CTST塔取代原　1400 mm浮阀塔,改造后C3、C4、C5的吸收率分别提高了60.1％、44.4％、55.1％,年增经济效益294万元.A re-absorbing tower, redesigned with the Combined Trapezoid Spray Tray (CTST), was an important column of the fluidized catalytic cracker unit (FCCU) with 0.8 Mt/a vacuum residuum in the refinery division of Beijing Yanhua Petrochemical company Let. (BYPC). And its diameter was 1 200 mm, with 30 CTST trays. This project had succeeded, and had been making a lot of benefits, that is, the absorbility of C3, C4, C5 was improved by 60.1%, 44.4%, 55.1%, respectively, and its economic effectiveness increased ￥2,940,000 per annum.
