Extractive distillation pdf

Distillation is a commonly used method for purifying liquids and separating mixtures of liquids into their individual components. Familiar examples include the distillation of crude fermentation broths into Extractive distillation performs the separation of close boiling components or azeotropes in the presence of a miscible, high boiling, relatively non-volatile component that forms no azeotrope with William Luyben L. О книге "Design and Control of Distillation Systems for Separating Azeotropes". Hands-on guidance for the design, control Extractive distillation is one of the most attractive approaches for separating azeotropic mixtures. Few contributions have been reported to design an extractive distillation for separating Proper operation of extractive distillation column re-quires knowledge about the product compositions during the operation of the system. Although product composi-tions can be measured on-line Washington: Amer Chemical Soc., 1972. — 187 p. Azeotropic and extractive distillations have been used through the years in the chemical industry to separate mixtures where the relative volatility of the The novel distillation pro-cess integration is the combination of different pressure thermally coupled distillation (DPTCD) and extractive distillation (ED). Both the new process and the conventional 4. Vacuum Distillation 5. Molecular Distillation 6. Fractional Distillation Under Reduced Pressure. 1.Simple Distillation Distillation of the substances in simple structure, that are readily volatile and Distillation is the MOST common separa-tion technique in chemical process industry, accounting for · Binary-mixture distillation · Multi-component distillation · Extractive & azeotropic distillation Although distillation is considered the most mature and best-understood separa- tion technology, knowledge on its manifold aspects is distributed unevenly among different textbooks and manuals. Extractive distillation is defined as distillation in the presence of a miscible, high-boiling, relatively non-volatile component, the solvent, that forms no azeotrope with the other components in the mixture. The method is used for mixtures having a low value of relative volatility, nearing unity.
