提高齐鲁乙烯装置高附收率的途径

APPROACHES TO INCREASE HIGH VALUE-ADDED PRODUCT YIELD OF QILU ETHYLENE PLANT

通过对影响齐鲁乙烯装置高附收率因素的分析,提出了优化原料结构、减少系统结焦和排放、优化裂解深度、优化工艺参数等措施,达到了降低产品夹带损失,延长运行周期,提升高附收率的目的。

Basing on the analysis of effect factors on high value - added product yield of Qi- lu ethylene plant, the paper put forth some measures, such as optimizing raw material propor- tion, decreasing coke and discharge of the system, optimizing cracking depth and process pa- rameters and etc. to reach the purposes of reducing entrainment loss of the product, prolonging operation period, raising high value -added product yield,
