Study of the Relationship between the Composition of Aqueous Mixtures Containing Esters and Alcohols and the Energy Efficiency of Separation Schemes
摘要
Abstract
The article demonstrates the possibility of predicting the energy consumption of process flow diagrams for separating mixtures of different compositions using the example of aqueous systems containing homologues of alcohols and alkyl acetates. Isomeric structures of product isolation schemes based on the use of conventional and (auto)extractive rectification are proposed. The static operating parameters of the columns are determined to ensure the required quality of product flows. The dependences of the change in the total energy consumption of the circuits on the molecular weight of the homologous components and the composition of the initial mixtures are revealed.
