Embodiment Construction

[0028] Exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, but are not intended to exhaust all possible ways of the present application, nor are they used to limit the scope of the present application.

[0029] The following outlines the technical idea of ​​the present application. This application proposes a carbon dioxide capture system based on phase change absorbents. The system replaces the desorption tower in the traditional carbon dioxide capture system with a heat exchange regenerator. When the phase-change absorbent is used, the viscosity of the rich-phase absorbent will not be reduced before decomposing, and the regeneration and circulation of the phase-change absorbent are realized with lower regeneration energy consumption.

[0030] In particular, in this em...

Abstract

The carbon dioxide trapping system based on the phase change absorbent comprises an absorption tower, a phase splitter, a first-class power device, a heat exchange regenerator, a heat pump and a plurality of second-class power devices, and a mixed absorbent outlet of the absorption tower is connected with an absorbent inlet of the phase splitter through one second-class power device. A lean-phase absorbent outlet of the phase splitter is connected with a mixed absorbent inlet of the absorption tower through a second-class power device, a rich-phase absorbent outlet of the phase splitter is connected with a rich-phase absorbent inlet of the heat exchange regenerator through a first-class power device, and a regenerated absorbent outlet of the heat exchange regenerator is connected with a first inlet of the heat pump; a first outlet of the heat pump is connected with a mixed absorbent inlet of the absorption tower, a heat exchange medium outlet of the heat exchange regenerator is connected with a second inlet of the heat pump, a second outlet of the heat pump is connected with a heat exchange medium inlet of the heat exchange regenerator through a second-class power device, and the heat exchange regenerator comprises a gas exhaust port. And the heat exchanger is used for discharging carbon dioxide desorbed from the heat exchange regenerator.

Description

technical field [0001] This application relates to the technical field of carbon dioxide capture, and in particular to a carbon dioxide capture system based on a phase change absorbent. Background technique [0002] Under the sustainable development scenario, global carbon emissions need to drop from 42 billion tons in 2019 to less than 10 billion tons in 2050, and achieve net zero emissions in 2070. Among the numerous CO2 reduction technologies, chemical absorption based on organic amine solutions has been used commercially. At present, the main problem faced by the chemical absorption method based on organic amine solution is that the energy consumption in the process of desorption of carbon dioxide is too high, which leads to high cost of carbon dioxide capture. [0003] Specifically, the traditional organic amine method is to make the flue gas containing a certain concentration of carbon dioxide enter the absorption tower, react with the organic amine as the absorbent t...
