This is a aspen plus simulation of isopropanol based chemical heat pump. Here the products (mixture of isopropanol, acetone and hydrogen) from endothermic reactor/reboiler gets separated in the distillation column. The top distillate namely acetone and hydrogen go to the exothermic reactor where as the bottom product which is majorly isopropanol goes back to the endothermic reactor. The configuration 1 involves an exothermic reactor, a distillation column, and an endothermic reactor. The configuration 2 involves the reboiler acting as an endothermic reactor. In this case there is no separate endothermic reactor.
