Abstract:

The current situation and development trend of ethylene/propylene industry and the connotation of chemical process intensification were summarized and refined. By deeply analyzing the latest key progress and trends of external field synergistic intensification, core reactor/equipment intensification, system coupling intensification and new material (media) intensification in ethylene/propylene production process, four suggestions on the development of process intensification technology in ethylene/propylene production process including accelerating the pilot and promotion of mature/near-mature process intensification technologies in key production processes, promoting the research and development of disruptive and platform process intensification technologies, emphasizing the overall optimization of the ethylene/propylene production process by coupled process technologies and playing the role of advanced information technology in accelerating the ethylene/propylene production process were proposed. It would provide an important reference for the formulation of the development strategy of olefin industry chain process intensification technology in China's petrochemical industry.

Key words: ethylene, propylene, process intensification
