A kind of azeotrope separation coupling process and device

Abstract

The invention discloses an azeotrope separation coupling process and device. The device comprises a supercritical fluid preparation part, an azeotrope separation part and a sampling part; a supercritical fluid preparation part is used for preparing supercritical fluid and supercritical The fluid passes into the azeotropic mixture separation part; the sampling part is used to collect and sample the separated samples in the azeotropic mixture separation part; the azeotropic mixture separation part includes a separation system and a sampler; the separation system includes a high-pressure separation kettle, There is a temperature-controlling jacket outside the autoclave and a temperature-controlled inner autoclave; the upper and lower ends of the high-pressure separation autoclave have a sample inlet and a sample outlet respectively, and there are two pipelines at the sample inlet, one of which is connected to the sampler A sampling channel is formed, and another pipeline is connected to the supercritical fluid preparation part to form a channel for the supercritical fluid to flow into the high-pressure separation kettle. The invention can explore the application prospect of using thermal diffusion effect combined with supercritical fluid to separate binary component azeotrope.

Description

technical field [0001] The invention relates to the technical field of azeotrope separation process and chemical separation equipment, in particular to an azeotrope separation coupling process and device. Background technique [0002] Mixture separation technology is an important technical means in the chemical production process. The chemical production process that has been widely used at present includes: the extraction of raw materials, the separation of intermediate products, the purification of products, and the treatment of discharged waste water and waste gas. More or less, chemical separation technology will be used; in chemical production and pharmaceutical manufacturing, binary component azeotropes are important chemical raw materials and solvents, but currently they are facing binary azeotropes in actual production and manufacturing. The problem of recovery and reuse of organic solvents in compound components, especially after some solvents form azeotropes, it is...
