Saving primary energy consumption through exergy analysis of combine distillation and power plant / Alhassan Salami Tijani, Nazri Mohammed and Werner Witt

Industrial heat pumps are heat-recovery systems that allow the temperature of waste-heat stream to be increased to a higher, more efficient temperature. Consequently, heat pumps can improve energy efficiency in industrial processes as well as energy savings when conventional passive-heat recovery is...
