摘要
利用Aspen Plus软件对催化裂化装置汽柴油脱空度进行模拟研究,分析了汽提介质种类和用量、稳定汽油干点、分馏塔中段回流量对粗汽油和轻柴油产品质量、稳定汽油产量和气压机入口流量的影响,优化催化裂化装置产品质量,增加高价值产品稳定汽油产量,降低装置能耗。研究结果表明汽提介质采用低低压蒸汽或低压蒸汽,汽提蒸汽流量控制在3%~4%,并控制稳定汽油干点在200℃左右,对控制产品质量、稳定汽油产量和降低装置能耗比较有利。
The Aspen Plus simulation software is used to study the product quality optimization of FCC unit.The influence of the type and amount of stripping medium,the dry point of stabilized gasoline and the pumparound flowrate of main fractionator on the product quality of crude gasoline and light diesel,the output of stablized gasoline and the inlet flowrate of wet gas compressor is studied.Based on the study,the product quality of FCC unit is optimized,the output of high-value product stabilized gasoline is increased,and the energy consumption of unit is reduced.The results show that using low-low pressure steam or low pressure steam as the stripping medium,controlling the stripping steam flowrate within 3%~4%of diesel flowrate and controlling the dry point of stabilized gasoline at about 200℃are beneficial to controlling product quality,stabilizing gasoline output and reducing the energy consumption of FCC unit.
