Binary component azeotrope separation system

Abstract

The invention relates to the technical field of chemical engineering, and discloses a binary component azeotrope separation system. The system comprises a high-pressure tower, a low-pressure tower, ahigh-pressure tower reboiler and a compressor, wherein the high-pressure tower is provided with a mixed raw material inlet, a lower outlet of the high-pressure tower is connected with a cold side inlet of the high-pressure tower reboiler, a cold side outlet of the high-pressure tower reboiler is connected to the high-pressure tower, and the lower outlet of the high-pressure tower is also connectedwith a first component outlet; an upper outlet of the high-pressure tower is connected with a feed port of the low-pressure tower, a lower outlet of the low-pressure tower is connected with a secondcomponent outlet, and an upper outlet of the low-pressure tower is connected to an inlet of the compressor; and an outlet of the compressor is connected to a hot side inlet of the high-pressure towerreboiler, and a hot side outlet of the high-pressure tower reboiler is connected to the mixed raw material inlet of the high-pressure tower. According to the binary component azeotrope separation system provided by the invention, efficient separation and recovery of binary component azeotrope are realized; and meanwhile, operation energy consumption of a device is greatly reduced, and the binary component azeotrope separation system has remarkable energy-saving, environment-protecting and economic benefits.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a binary component azeotrope separation system. Background technique [0002] Binary component azeotropes mostly exist in chemical industry and medicine, and are important chemical raw materials and solvents. In the fields of chemical industry, fine chemical industry and pharmaceuticals, we often face the problem of recycling organic solvents of binary azeotrope components. Some solvents form azeotropes, which are difficult to separate by ordinary distillation methods. [0003] In the industry, a large part of the binary component azeotrope waste liquid is incinerated, but the binary component azeotrope is prone to produce harmful substances such as carbon monoxide, carbon dioxide, nitrogen oxide, and hydrogen cyanide during the incineration process. The environment has caused great damage. Therefore, the separation and purification of the binary component azeotrope m...
