Combining Special Techniques when Developing Separation Schemes for a Methanol + Water + Methyl Methacrylate Mixture.

The article is devoted to improving the separation technology of the methanol + water + methyl methacrylate mixture. Several alternative variants are proposed: separations based on the application of auto-extractive distillation and a combination of distillation and splitting process. The separation schemes are aimed at separating all components in pure form and increasing the yield of methyl methacrylate. A computational experiment is carried out to determine the operating parameters of the columns to ensure the production of substances of a given quality. The most energy-efficient scheme is based on the use of auto-extractive distillation and a combination of distillation with splitting process. [ABSTRACT FROM AUTHOR]
