1000kt/a连续重整装置双苯收率低原因分析

The Analysis of the Reason of Double Benzene Low Yield in 1000 kt/a Continuous Reforming Unit

分析中国石化安庆分公司100万吨/年连续重整装置双苯收率低主要原因是重整脱戊烷塔底油干点高导致重整反应温度提温受限,反应苛刻度低,双苯收率低。介绍了装置优化的措施,并提出了具体的解决方案,为装置提高经济效益创造条件。

Analysis the main reason of double benzene low yield in Anqing Branch of Sinopec one million tons/year continuous reforming unit. It is due to the dry spot of depentanizer bottoms oil is too high lead to increasing the reforming reaction temperature is limited, the reaction severity is low, so double benzene yield is low. Describes the continuous reforming unit optimization measures and proposed specific solutions, create conditions for the continuous reforming unit to improve economic efficiency.
