  干气预提升
     Various measures were taken to lowering the catalyst consumption in a residue fluid catalytic cracking unit (RFCCU) in Petrochemical Complex of Shengli Oil Field, such as dry gas pre-lifting, dry gas atomization, addition of termination agent into the lift pipe, employment of metal passivator, small automatic feeding system, high-efficiency atomization-feeding nozzles and efficient stripping technique. As the result, the catalyst consumption was lowered from 1.46 kg to 1.05 kg per ton of feed oil.
     胜利石油化工总厂重油催化裂化装置采用干气预提升、干气雾化、提升管注终止剂、金属钝化剂、自动小型加料系统、高效雾化进料喷嘴和高效气提技术,改善了催化剂的使用环境,使催化剂的活性和选择性得以充分发挥,装置催化剂吨油单耗由1 46kg·t-1降低到1 05kg·t-1,经济效益显著。
