Improving a process's efficiency by exploiting heat pockets in its heat exchange network

On the grand composite curve of a heat exchange network, a heat pocket exists when a local heat source above the pinch point or a local heat sink below the pinch point appears. In this paper, heat recovery in the heat pocket is presented by combining the pinch technology and exergy analysis. When th...
