Abstract

Firstly, the influence of relevant parameters on the economics of distillation plants involving closed heat pump cycles is scrutinized and the results are compared to the features of mechanical vapour recompression schemes. The results show that from an economic viewpoint the closed heat pump cycle has a similar effect to vapour recompression, but the closed cycle is less competitive. However, the closed cycle scheme can still be attractive due to safety and operability reasons. Preliminary screening for the selection of the most economic variant also shows that the application of the heat pumps outside the field of stand-alone columns is restricted to separating close boiling mixtures in a column of small pressure drop, since heat integration should be carried out before heat pumping. Secondly, a study of an industrial separation plant is demonstrated in a retrofitting situation. If adequate heat integration cannot be realized in the case of retrofitting situations, due to the inherent features of the plant, heat pumping can significantly improve the process performance.
