催化裂化油浆捕获沉降剂的工业应用

摘要

For the comprehensive utilization of oil slurry,to enhance the economic value of slurry oil refinery,reduce black product rate,improve the overall economic efficiency of the Petro China Lanzhou Petrochemical Company,a “comprehensive utilization of FCC slurry research group” was established,and 3 million tons of heavy oil catalytic cracking device was tested for oil slurry capturing settling agent (KOD CK2704A) in May 2013,where cooperative R & D unit(special mixed slurry oil pump) were applied to test capturing settling agent and agent oil mixed technology. The treated slurry quality meet the subsequent device processing requirements,500μL/L slurry are captured in three stage settlement agent fluence. Test data show that slurry ash decreased obviously,oil slurry ash content decreased from 0.65% to 0.069%,and average oil slurry ash removal rate reached 88.01%.%为综合利用油浆，提升油浆的经济价值，减少炼油厂的黑色产品率，提高中国石油兰州石化公司的综合经济效益，成立了“综合利用催化裂化油浆的课题攻关小组”，2013年5月在300万吨/年重油催化裂化装置上进行了油浆捕获沉降剂（KOD CK2704A）的工业试验。通过采用合作单位研发的油浆捕获沉降剂、剂油混合技术（专用混合泵），使处理后油浆质量满足后续装置加工要求，试验以500μL/L的油浆捕获沉降剂加注量进行了3个阶段，试验数据充分证明，油浆灰分下降明显，油浆灰分质量分数由0.65%下降至0.069%，油浆平均脱灰率达到了88.01%。
