“…Namely, a system is proposed for utilization of the energy flow of the products of the distillation columns using heat pumps (HP) (figure 1) [4,5]. The use of HP in the process of separation of substances allows, in addition to reducing consumption of thermal energy, to reduce the number of plates by changing the pressure in the columns and reduce the metal structure [6,7]. The unit (figure 2) works as follows: The initial blend is fed through the heat exchanger-heater 1 from below to the tube space of the column 2.…”

The results of computer simulation of industrial processes of separation of substances with the inclusion of a heat pump are presented. Designs of heat pumps of closed type, open type, like “pipe in pipe” are considered. In the simulation software Aspen HYSYS, the adequacy of the computer model of the “rectification unit – closed type heat pump” system was checked. The results of computer simulation of the “rectification unit – open-type heat pump ’pipe in pipe’” system are presented. This system allows to increase the efficiency of the unit by 9% compared with the system of separation of substances with the inclusion of an open-type heat pump and by 14% compared with a system with the inclusion of a closed-type heat pump.
