A suitable heat pump coupled to low-temperature sources can upgrade heat to higher temperatures. This is commonly achieved by consumption of electricity (vapor compression heat pumps) or by thermal means (vapor absorption and solid–gas sorption heat pumps). However, vapor compression and vapor absorption heat pumps are frequent, intensive research on chemical heat pumps conducted in recent years. Since no mechanical compression is required for attaining a considerable temperature rise, chemical heat pumps expected to take an important role in the utilization of solar, geothermal or waste-heats. They do not require electric power and generally have higher thermodynamic efficiencies than mechanical heat pumps. This paper present a detailed simulation of Isopropanol-Acetone-Hydrogen Chemical Heat Pump. The CHP system was simulated using ASPEN PLUS and further analyzed and optimized for the energy efficiency. Under the optimum distillation column condition (Table 2), the COP and exergy efficiency was considered0.25 and 0.33 respectively, which proved that simulation results are greater than the reported results. The developed model can be invoked as a guide for understanding the reaction kinetics for CSTR reactor.
