Способы экономии энергоносителей в ректификационных установках

Abstract

The ways of energy consumption reduction for rectification process of homogeneous liquid mixture “water-acetic acid” are discussed. The various approaches of energy saving retrofit are proposed. The heat of top effluent and residue may be used to preheat the feed. The use of top vapour compression (heat pump case) is considered. To optimize the heat recovery the methods of pinch-analysis are used.
