The author proposed a method for calculating an adsorber for removing water from dichloromethane, which involves modeling the process in the Aspen Adsorption program. They used experimental breakthrough curves, conditions of adsorption equilibrium, kinetics, heat transfer, and mass transfer. The developed method makes it possible to determine the breakthrough time and liquid temperature for different values of the adsorber productivity, its dimensions, and the initial water content in dichloromethane. The author found that a “hot spot” appears in the adsorber because of heat release, and the temperature of the liquid in it can differ significantly from the initial one. This factor is essential for choosing the size of the apparatus.
