旋流快分与环流汽提耦合技术的工业应用
|
摘要
为了解决某重油催化裂化装置沉降器及汽提段存在的问题,进行了旋流快分与环流汽提耦合技术在催化裂化装置的改造,对比分析改造前后的原料性质、主要操作条件、能耗等数据,发现改造效果显著,轻质油收率增加3.46%,液体收率增加1.44%,焦炭产率降低1.43%,大大提高了装置的经济效益。2015年8月装置一次开工正常后运行平稳至今。
In order to solve the settlement of a heavy oil catalytic cracking unit and the problems existing in the stripping section,the circulation of the vortex quick points and stripping coupling technology in catalytic cracking unit are reformed. Comparative analysis on before and after transformation of the raw material properties,the main operating conditions,such as energy consumption data,proves that the transformation effect is remarkable: light oil yield increased by 3. 46%,liquid yield increased by1. 44%,the coke yield reduced by 1. 43%,greatly improving the economic efficiency of the plant. In August 2015,the device was running smoothly after normal operation.
