Abstract:

The study on reaction area layout is a core and crucial aspect of polyethylene plant design. Taking the design of the reaction area of a domestic gas-liquid polyethylene plant as an example, this paper systematically introduces the process flow of the reaction area in such plants, focusing on the establishment of equipment layout plan for the reaction area and the design ideas of important piping systems such as feeding system, discharging system, terminator system, condensate system, and circulating gas system. At the same time, this paper refers to previous design experience of such plants, compares the characteristics of different schemes, and provides references for the subsequent design and optimization of the reaction area in similar plants.

Key words: gas-liquid polyethylene, reaction area, equipment layout, piping layout
