Abstract:The transition to sustainable industrial energy systems requires innovative solutions to enhance efficiency and reduce carbon emissions. This study evaluates the feasibility of integrating heat pumps into Teijin Aramid’s Emmen facility to provide process heat at 60°C. Conventional heating and cooling methods, such as steam and glycol chillers, result in high operational costs and environmental impact, highlighting the need for more efficient alternatives. Four heat pump concepts were analyzed: independent, centralized, clustered, and cascade configurations. Centralized and cascade systems showed the highest efficiency, with COP values of 4.32 and 4.48, respectively. Mixing at the heat pump inlet improved performance by reducing exergy destruction, whereas outlet mixing caused inefficiencies. Refrigerant selection was crucial for efficiency and sustainability. R1234ze(Z) and R1233zd(E) offered high COP and low GWP, with R1233zd(E)/R1233zd(E) achieving the best performance in cascade configurations (COP = 5.09). While heat pumps could reduce energy costs by up to 52%, economic feasibility remains challenging due to high initial investments and a five-year payback requirement. This study identifies optimal heat pump configurations and refrigerants that improve efficiency, reduce costs, and lower emissions, providing valuable insights into heat pump adoption for industrial decarbonization.
