Abstract:

The growth trend of ethylene capacity and the advantages of large-scale ethylene plant are introduced in this paper. Large-scale schemes for ethylene plant are preliminarily discussed combined with key equipment in ethylene plant such as cracking furnace, charge gas compressor, refrigerant compressor, large column, heat exchanger, and large valve. The main control points are pointed out based on the current technology level and design and manufacturing capabilities. The current status of large-scale ethylene plants at home and abroad is briefly summarized, and the construction methods and considerations are proposed.

Key words: ethylene plant; economies of scale, large-scale, maximum capacity
