摘要
Abstract
The development of conventional ethylene recovery technology is briefly discussed. Little advancement has been made in the Front-end Demethanizer Technology since binary and ternary refrigeration are commercialized. As the advanced recovery technology and low energy consumption technology are utilized,the Front-end Depropanizer Technology has made great progress. Nearly no progress in the process of the Front-end Deethanizer technology is reported. The domestic development of ethylene recovery technologies in China is also presented. New technologies,such as 800 kt/a ethylene plant based on the Front-end Depropanizer Technology and 1000 kt/a ethylene plant based on both senquencing separation and progressive separation are successfully developed after 30 years of hard work and research. The general performance of such technologies is reviewed and analyzed. Domestic manufacture and scale-up of major pieces of equipment,such as three compressors and cold box are realized. These pieces of heavy equipment are now running smoothly in 1000 kt/a ethylene plants and reach the advanced standards of imported equipment.关键词
