exergy analysis and an exergoeconomic evaluation to identify the potential energy savings in distillation processes. Methods … for calculating the avoidable/unavoidable exergy destructions and investment costs for distillation columns, and hot …-utility/cold-utility heat exchangers are proposed. For a distillation column, the unavoidable exergy destruction is estimated through the …

Distillation is one of the most widely used separation units that consumes the largest amount of energy in chemical and … petrochemical industries. Heat integration of thermally coupled distillation column is one of the methods to reduce energy …-consumption. This paper provides a comparison between two simple columns with direct configuration and thermally coupled distillation …

heating method has a large number of actual and potential application exits in food industry, water distillation, waste …

Despite the fact that a stand-alone ideal heat-integrated distillation column (ideal HIDiC) can be thermodynamically …

Most of the methods developed for efficiency estimation of distillation columns were based on the empirical mass … efficiency (and mass and heat transfer coefficients) of distillation columns containing structured packings. This method has … of any structured packing, including new ones, in distillation columns. …
