CO2-enriched amine solution regeneration energy consumption reducing novel catalytic desorber

Abstract

The invention discloses a CO2-enriched amine solution regeneration energy consumption reducing novel catalytic desorber. Compared with traditional desorbers, the CO2-enriched amine solution regeneration energy consumption reducing novel catalytic desorber introduces a catalytic reactor into a traditional CO2 desorption process without changing the technical process, the pipe layout, the heating manner and the like of the traditional desorbers; the catalytic reactor is filled with solid catalysts, CO2-enriched amine solution enters into the catalytic reactor via the bottom of the catalytic reactor under the action of a pump, and through full contact between the catalysts and the CO2-enriched amine solution, the performance of the catalysts can be maximized. The CO2-enriched amine solution regeneration energy consumption reducing novel catalytic desorber is mainly composed of the catalytic reactor and a packed tower; introduction of acid catalysts accelerates the regeneration rate of theCO2-enriched amine solution, reduces the regeneration temperature and accordingly achieves the aim of high-efficiency and low-energy-consumption regeneration of the CO2-enriched amine solution. The CO2-enriched amine solution regeneration energy consumption reducing novel catalytic desorber is higher in catalytic performance than existing catalytic desorbers and the traditional desorbers.

Description

technical field [0001] The invention relates to a novel catalytic desorption tower for the regeneration of carbon dioxide-enriched amine solution. Background technique [0002] In recent years, due to the extensive use of fossil energy such as coal, oil, and natural gas, the greenhouse effect has become increasingly serious, and the global climate change caused by it has threatened the survival and development of human beings, while carbon dioxide (CO 2 ) is one of the most important greenhouse gases. [0003] Existing carbon capture technologies mainly include three technologies: pre-combustion capture, oxygen-enriched combustion capture and post-combustion capture. Among them, post-combustion capture technology is the most mature and widely used carbon capture technology. Post-combustion carbon capture technology There are mainly chemical absorption method, physical adsorption method and membrane separation method. In the chemical solvent absorption method, organic amine...
