Abstract

Abstract:

As the feedstock to the 220 kt/a ethylene plant at PetroChina Dushanzi Petrochemical Company becomes lighter, the cracking gas components becomes lighter, and some problems such as high suction pressure and low discharge pressure gradually emerged in the cracking gas compressor. As a result, the ethylene yield and the output cannot meet the requirements at the same time. This paper introduces the analysis and investigation process of the influence of lighter cracking gas components on cracking gas compressor, and puts forward some optimization measures and suggestions.

Key words: cracking gas compressor, average molecular weight, ethylene yield
