Abstract: Many efforts are dedicated globally to industrial waste heat recovery in hope of reducing energy consumption and pollutants emission. A novel system composed of direct heat exchanger and hydride heat pump is proposed to achieve this target, which could effectively utilize the sensible heat from a process stream at both high and low temperatures. In this paper, we present the fundamental procedure for formulation of such a system, including heat duty assignment, working pair screening and cycle modification. In addition, thermodynamic analysis on the performance of the integrated system is conducted, and the results exhibit the possibility of building competitive alternative to existing absorption heat exchanger (AHE). Finally, the impacts of design variables and material properties on system performance are discussed, providing a benchmark for applying such a system on various occasions.
