An intermediate heating and cooling method for a distillation column
TLDR
In this article, the authors proposed a quantitative method to determine the feasible domains for the use of a sideboiler and a side-cooler, and to clarify the important relationship between temperature and the minimum exchanging heat load of heat source and/or coolant at any plate.Abstract:
To save energy in a distillation column, engineers have discussed the application of side-boilers and side-coolers and heat pumps to a distillation column. But no quantitative method which represents the relationship between temperature level and the minimum exchanging heat load of heat source and/or coolant at any plate has been developed. It is very difficult to design a distillation column with such equipment. This paper represents the energy-saving effects of a side-boiler and a side-cooler on a distillation column on the basis of exergy concepts, and then proposes a quantitative method to determine the feasible domains for the use of a side-boiler and a side-cooler, and to clarify the important relationship mentioned above. This method can be used to design a distillation column with a heat pump and a multi-effective distillation system.read more

Exergy analysis of distillation processes
TL;DR: In this paper, the authors proposed a new type of fractional distillation in which the reboiler and the condenser normally located at the bottom and at the top of distillation column, are replaced by two heat exchangers integrated in the column itself.
