2000年12月9日,我国第一套大型国产化100 kt/a聚酯装置在仪征化纤股份公司建成投产,并生产出合格产品。 100 kt/a聚酯国产化装置是国家“九五”重大科技攻关项目和中国石油化工集团公司“一条龙”攻关项目。在消化吸收引进技术的基础上,他们通过大量实验,逐步掌握了聚酯酯化和缩聚反应过程规律,确定了大型装置的工艺流程,工艺参 On December 9, 2000, China’s first large-scale domestically produced 100 kt/a polyester plant was completed and put into production at Yizheng Chemical Fiber Co., Ltd., and qualified products were produced. The 100 kt/a polyester localization device is the national “Ninth Five-Year Plan” major scientific and technological research project and the “through-train” research project of China Petroleum & Chemical Corporation. On the basis of digestion and absorption of imported technologies, they gradually mastered the process of polyester esterification and polycondensation reaction through a large number of experiments, and determined the process flow and process parameters of large-scale devices.
