摘要
针对某厂100×104 t/a催化裂化装置在负荷较高时总液收率低的问题,通过优化平衡催化剂活性、原料油预热温度、反应温度以及二再密相温度等参数,研究了进料负荷在3200t/d时各参数对总液收率的影响。研究结果表明,平衡催化剂活性为61、原料油预热温度为195℃、反应温度为495℃±2℃,以及二再密相温度为665℃±5℃时,产品液体总收率达到88.9%,比优化前提高了2.6%,其效果明显,使企业的经济效益和社会效益得到了明显提高。
Aiming at the problem that the oil yield of 1000×103 t/a FCC unit is lower when the load is high,by optimizing balance catalyst activity,preheating temperature of feed oil,reaction temperature and second regeneration dense phase temperature,the effect of these parameters on the total oil yield was researched when the feed load was 3200 t/d.The results show that when the balance catalyst activity is 61,the feed preheating temperature is 195 ℃,the reaction temperature is(495±2) ℃ and the second regeneration dense phase temperature is(665±5)℃,the total oil yield reaches 88.9%,over 2.6% than non-optimum one.
