武汉石油化工厂催化裂化装置为高低并列式分子筛提升管催化裂化,设计能力为60万吨/年.近几年来,为了降低装置能耗,提高经济效益,先后两次对换热流程进行了调整.改造后,1983年9月进行标定,回收能量923.5万千卡/时,可降低装置能耗12.7万千卡/吨原料油.改造后的流程:1.原料油先与一中段循环回流换热,由118℃升温到143℃,换热量为109.5万千卡/时;然后再与轻柴油换热,到154℃,换热量为62.1万千
Wuhan Petrochemical Plant catalytic cracking unit for the level of parallel molecular sieve riser catalytic cracking, design capacity of 600000 tons / year.In recent years, in order to reduce the unit energy consumption and improve economic efficiency, the heat transfer process has been twice in succession After the transformation, calibration was carried out in September 1983, and the energy recovered was 9,225,000 kcal / h, which could reduce the energy consumption of the device by 127,000 kcal / ton of feedstock. After the reformation: 1. The feedstock was circulated back to the middle section Heat, heated from 118 ℃ to 143 ℃, the heat exchange capacity of 1.095 million kcal / h; and then heat with light diesel oil to 154 ℃, heat exchange of 62.1 million
