Technoeconomic and Greenhouse Gas Impact Analysis of a Twin-Screw compressor High Temperature Heat Pump for Spray Drying

Original language description

Process heat is one of the largest drivers of industrial energy demand and greenhouse gas emissions. Here, we consider a case study of a spray drying facility that requires 880 kW of heat from 8AM-5PM every day, and examine the potential costs and emissions impacts of adopting a high temperature heat pump (HTHP) to provide some of this process heat. For this type of facility, we generate the natural gas and electricity demand, accounting for both heating efficiency of a natural gas burner system or the coefficient of performance (COP) of the HTHP system, respectively. Using this information about the quantity and timing of natural gas and electricity demand, we then consider the private energy costs to operate spray drying systems with HTHP and natural gas heaters. In addition to the private costs of operating spray dryer systems, we consider the greenhouse gas emissions of the natural gas and the electricity used to meet the heat demand. Using both the private and social costs associated with natural gas and HTHP spray drying systems, we calculate the net present value of switching to HTHP. We find that the private costs of operating a HTHP are higher than the cost of operating a natural gas-fired spray dryer in all subregions, but, when we consider the social costs of greenhouse gas emissions, there are several subregions with net benefits from HTHP systems.
