Abstract: Aluminum alkyls are widely used in the polyolefin industry. Based on the characteristics of aluminum alkyl chemicals and the practical engineering experience, this article takes triisobutyl-aluminum as an example to summarize the regional division in aluminum alkyl area and the design points of equipment layout, process design and safety system in polyolefin unit, and proposes some key points to be noted in the design of relevant areas. 

Key words: aluminum alkyl, process design, polyolefin
