| Abstract: | Analysis of the bottleneck in HEN based on simulation technology of HEN, optimization technology of single heat exchanger and the principle of pinch technology have been executed to realize the revamping of HEN with minimum investment and engineering quantity. Especially, the countenneasures for vaporization of heated streams, engendering air resistance and pressure drop increasing in heat exchange process have been proposed. |
