The heat coupled distillation column which applies the principle of internal heat integration between the rectifying section and the stripping section of a distillation column by increasing the temperature of the rectifying section with a compressor attracts extensive attention worldwide for its high thermodynamic efficiency. In this study, the economic features of a heat coupled distillation column (HCDC) are investigated and compared to a conventional column and a commercial column with vapor recompression system (VRC) for the separation of propylene-propane mixture. The economic analysis indicates that HCDC has 10 – 20 % total annual cost (TAC) saving associated with VRC, which appeared to be strongly sensitive to the pressure ratio.
