Acetone recovery unit is an important unit using acetone as a solvent for chemical production enterprises , steam parse - Distillation acetone recovery process of high energy consumption , poor process safety and stability ; water absorption - distillation , activated carbon adsorption - acetone recovery process uses less energy, process safety and stability , is the best alternative processes . In this paper, based on detailed research , chemical process simulation technology for water absorption - Distillation acetone recovery process development . ASPEN PLUS process simulation software, and the water absorption process modeling, simulation , process simulation reported in the literature and the actual conditions exactly . A sensitivity analysis on this basis , the water absorption process , including temperature and concentration of absorber temperature , VLA gas absorbing liquid reflux position , the reflux ratio and the influence of the temperature on the absorption effect . At the same time , using the ASPEN PLUS process simulation software the current rectification process simulation results show that the process simulation results with the current operating conditions of distillation exactly . A sensitivity analysis on this basis , the process of distillation , obtained the best feed location of the distillation column , the feed concentration , feed temperature and the influence of the operating pressure on the energy consumption of distillation process . On the basis of the above work , a suitable water absorption - Distillation acetone recovery process , key equipment absorber and distillation column design calculations , technical and economic analysis and new technology .
