Study on the Clean Recycling Technology of Dichloromethane
Abstract: With the rapid development of organic synthesis and petrochemical industry， and the emissions of industrial organic waste gas is continujava script:void(0)e to increaing, types of organic compounds that entering the atmosphere become more and more ,and the air pollution is turn to serious day by day. Methylene Chloride is a volatile halocarbons pollutants ，and are carcinogenic to humans, is one of the world's most important gaseous organic pollutants, therefore, recovery dichloromethane has become a pressing issue. This article has mensurates the Henry coefficient and the effection of absorb in absorbent of dichloromethane , and calculated the equipment parameters of flow scheme . According to the experimental data of absorbing and balancing ,bring forward a more reasonable treatment processes. Measured Henry coefficient of 1.33 for H, equilibrium constant m of 1.8 x10-3 absorption efficiency reached 92.67% in an average.
