synthesis of heat integrated multi-component distillation systems is complex
due to its huge search space for structural combination and optimization
computation. To provide a systematic approach and tools for the synthesis
design of distillation systems, a new method for modeling heat integrated columns
is presented, and the operating cost objective function is minimized by
improved harmony search algorithm (IHS). This paper studies a quick method for
the synthesis of heat integrated distillation column sequences and IHS -based
optimization strategy for the optimization of separation sequences with their
heat integration.
