摘要
介绍MGD技术和不完全再生技术的组合式工艺在ARGG装置上的工业应用情况,该组合式工艺是催化裂化装置的扩能改造配合清洁汽油升级的有效途径;对不同原料油性质变化有较强的适应性;对组合式工艺的反应再生系统的工艺计算和热平衡计算表明,该组合式工艺有较好的操作弹性;低温、高剂油比和高汽油回炼比有利于降低产品汽油的烯烃含量;恩氏蒸馏95％点低于90℃的催化裂化轻汽油是较好的回炼介质,能较好地降低产品汽油的烯烃体积分数到34．4％;该组合式工艺有良好的经济效益,年创效益8 177×104 RMB￥。
The commercial application of combination process of MGD and partial-burn regeneration on ARGG unit is described. The combination process, which has higher tolerability to the variations of feedstock properties, provides an effective means for FCCU capacity expansion and clean fuels and gasoline upgrading. It also offers the advantages of greater turn-down ratio, lower temperature, higher catalyst to oil ratio and high- er gasoline recycle ratio, which are favorable for reducing gasoline olefins. The light FCC naphtha of lower than 90℃ of Engler Distillation is a good recycle media, and olefin in product gasoline can be reduced to 34.4 v%. An annual profitability of 81.77 million Yuan （RMB） can be achieved.
