Methods of Optimization Thermodynamics in Distillation Processes

The methodology of optimization thermodynamics was used for the mathematical description and optimization of distillation processes. The following problems were considered: construction of a set of feasible operating conditions of columns separating binary and multicomponent mixtures, selection of the sequence of separation of a multicomponent mixture, feasibility of using a separating agent, selection of the feed temperature and feed point, and optimization of parallel and sequential systems of distillation columns. Calculation formulas for entropy production and heat transfer coefficients in the reboiler and reflux condenser of the column were obtained.
