Abstract

Abstract: There is a considerable amount of low-temperature waste heat in petrochemical plants. Lithium bromide absorption refrigeration is an effective form of waste heat recovery. This paper introduces the principle and characteristics of lithium bromide absorption refrigeration, and takes a coal chemical project as an example to discuss the engineering situation, design scheme, design flow, main equipment and parameters, automatic control scheme, design points and economic analysis. The study shows that lithium bromide absorption refrigeration can effectively recycle the low-temperature waste heat in the plant, greatly improving the efficiency of energy utilization. Meanwhile, the recovery cycle is short and the enterprise cost is reduced.
