doi:10.19596/j.cnki.1001-246x.8511

Abstract

Abstract:

An extended node unstructured model is established, and an additional cold and hot stream is set up to match with the conventional hot and cold stream to determine the generation of cold and hot internal utilities, so as to realize independent matching of utilities at any position on the cold and hot flow unit and improve the degree of freedom of the model. A forced evolution random walk algorithm was introduced to optimize three practical engineering examples 9SP, 10SP and 15SP, which saved 5 600＄·a^-1, 848＄·a^-1 and 4 455＄·a^-1, respectively, compared with the optimal literature. It shows that application of the extended model obtains more economical heat exchange network designs, and has a stronger universality as well.

Key words: node-wise non-structural model, heat exchange network optimization, internal utilities, optimization
