  Heat pump assisted distillation with an external working fluid is one of the most obvious methods to reduce the energy consumption in a distillation p Cited by: 2. More than one hundred and fifty references for heat pump assisted distillation systems have been listed and classified under the following categories: heat pump assisted distillation (1) with an external working fluid, (2) using one of the distillation components as the working fluid, (3) overall assessments and (4) experimental by: 3.   This paper presents a simulation of an ethanol–water distillation column assisted by a vapour‐compression heat pump. The heat pump is of the external type, i.e., it uses a working fluid (refrigerant) different from that of the by: 9. The distillation column has been designed on the basis of conventional design procedures. Valve trays were chosen to provide operational flexibility. R was chosen as the working fluid for the mechanical vapour compression heat pump. The heat pump system has been designed to match the heat loads determined for the column.

Energy efficiency of acetone, butanol, and ethanol (ABE) recovery by heat-integrated distillation. Bioprocess and Biosystems Engineering , 41 (3), DOI: /sz. Iulian Patraşcu, Costin Sorin Bîldea, Anton A. Kiss. Heat pump assisted azeotropic DWC for enhanced biobutanol separation.   Null [6] has discussed the different configurations of electrically driven heat pump-assisted distillation. The widely used methods are: direct vapour recompression, external working fluid (closed cycle heat pump) and bottom flashing (Fig. 1). Ranade and Chao [2] have presented guidelines of where and when to use the different kind of heat pumps.   However, this external vapor recompression scheme, like the absorption heat pump system, involves the use of working fluid and hence suffers from the same drawbacks associated with the working pair. This closed system approach is generally preferred when the column fluid is corrosive or is not a good refrigerant [38].   One scheme is to use an external heat pump circuit in which a refrigerant fluid, different from the mixture in the column, is employed. heat pump assisted distillation, heat integration between distillation columns and the background process, and heat integration between heat pumps and the background process. With the across-pinch rule.

Although the economics of heat pump assisted distillation systems appear to be attractive for certain mixtures, there is no published literature dealing with design and performance data. Heat pumps in distillation. 3. Distillation column – heat pump configurations. The objective of a heat pump in distillation is to use the heat of condensation released at the condenser for evaporation in the reboiler. As the temperature at the reboiler is higher a heat pump is required. Heat pump assisted distillation. VI: Classified references for heat pump assisted distillation systems from to February Abstract More than one hundred and fifty references for heat pump assisted distillation systems have been listed and classified under the following categories: heat pump assisted distillation (1) with an external working fluid, (2) using one of the distillation.   Enhanced performance of wet compression-resorption heat pumps by using NH3-CO2-H2O as working fluid.
