Abstract
Economic and environmental analysis of isopropanol-acetone-hydrogen based chemical heat pump (IAH-CHP) were studied at the endothermic reaction temperatures (heat input) of 100°C-200°C at gross temperature lifts of 50°C, 75°C and 100°C and heat output capacity of 500 kW.
Attached files are the following:
Equipment cost correlations along with key parameter values used in economic analysis.
List of ecoinvent processes used in Life cycle assessment studies.
Sample economic calculation file for 130°C/205°C case.
Optimization results - decision variable values along with cost details for all the cases studied.
