Abstract:

ln this paper, the source of waste heat and the principle of waste heat relrigeration in coal chemical industry are summarized ,and the process flow of waste heat relrigeration coupling compression refrigeration is designed. The feasibility of this process is demonstrated from the aspects of reirigeration principl, case analysis and economic benefit evaluation, etc. Results show that this process can recover waste heat, reduce energy consumption and improve economic benefits of enterprises

Keywords: waste heat recovery / lithium bromide refrigeration / compression refrigeration
