摘要：

Possible structures for an Internal Thermally Coupled Distillation Columns (ITCDC) are suggested and compared to a conventional column and a column with a vapour recompression system (VRC) taking a propylene/propane splitter as the base case. Thermal efficiency of the ITCDC appeared to be strongly sensitive to column structure and a highly efficient asymmetrical structure with stripping section stages thermally interconnected with the same number of stages in the upper part of the rectifying section emerged as the most promising one. The relationships among pressure ratio of rectifying section to stripping section, energy consumption and heat transfer area were also discussed.
