Progress in heat integration of batch processes

Research of heat integration in batch processes can promote the sustainable development of batch process and improve its economic efficiency and technical competitiveness. This article reviewed the progress of heat integration in batch process based on integrated process optimization. Three universal applied models based on graphic technique were summarized, and the discussion and comparison for the characteristics of different algorithms used were given. Current researches could be classified into three areas: the design of heat exchanger network, thermal storage systems and heat integration with scheduling. The bottleneck and research significance of them were commented. It was pointed out that heat integration was a research hotspot of batch process, and the research of the collaborative optimization for heat integration and batch scheduling was necessary, leading to optimal design of the system. More requirements needed to be met in the optimal design of batch process wherein the uncertainties and constraints made the problem more difficulty.
