摘要
围绕资源综合利用、节能减排及环境保护等发展方向,强调化工单元应用的重要性,介绍了萃取精馏技术在工业过程中的应用及对节能、减排的影响;列举萃取精馏技术对乙醛酯的制备及混合二氯苯分离过程的影响,设计萃取精馏分离工艺方案,采用三对角距阵法模拟萃取分离结果,考察物料进料位置、进料量、回流比及塔板数对分离过程的影响,优化分离过程的工艺条件,实验和模拟计算结果为工业生产提供指导意见。
The stress is laid on the importance of chemical unit used for the comprehensive utilization of resources, energy saving,pollutant discharge reduction, and environment protection. The apphcation of extractive distillation in the industrial process is introduced with the impact on the energy saving and pollutant discharge reduction pointed out. The effects of extraction distillation are entanerated to DEM preparation and separation of dichlombenzene. The technological process is designed and the result of extractive separation is simulated by the triangle matrix method and the effects of material position,feed quantity,reflux ratio and theoretical plate number, etc., on the separation process are inspected. The technological conditions of separation process are optimized,The results made by the experimental and simulative calculation will provide a guideline for the industrial production.
