The preliminary design of the annual 35 thousand tons of dichloromethane chloride absorption section
Abstract ： Dichloromethane was one of four methane chlorides, it is by chlorine atomssubstituted compounds generated methane molecules in the two hydrogen atoms. Methylenechloride is a colorless transparent liquid, easily volatile. Dichloromethane in actual industrialproduction and other fields in the range of application is extremely extensive, so for people'sdaily life has a important significance. This graduation design is for annual 35000 tons ofdichloromethane chloride absorption section of the preliminary design, the first is fordichloromethane and the physical properties and chemical properties and production process ofthe introduction, and then consider the scale of production and the actual situation of ourcountry, production capacity and economic conditions determine the method of productionprocess, and in accordance with each main reactor for material balance, heat balance, effectiveenergy utilization ratio is calculated, the last is of some major equipment selection calculation,and draw the process flow diagram, the map of major equipment. This design mainly uses thefine chemical, chemical process design contents related to organic chemistry, principles ofchemical engineering, chemical thermodynamics, chemical process, separation engineering,chemical equipment, CAD and other disciplines related knowledge.
