Abstract

Abstract: In this paper heat exchange coefficient and separation efficiency of an annular structured internal heat-integrated distillation column (HIDiC) were experimentally measured. About 50% heat of the inner column could be transferred to the outer column. The overall heat exchange coefficient decreased with an increase in pressure ratio of the inner column and the outer column, but was little affected by the F-factor. The increase of the pressure ratio decreased obviously the separation efficiency of the outer column but had little effect on that of the inner column.

Key words: Internal heat-integrated distillation column, Overall heat exchange coefficient, Separation efficiency
