Solid-state amine fluidized bed reactor

Abstract

The present invention relates to the field of chemical industry equipment, particularly to a solid-state amine fluidized bed reactor, which comprises an absorption reactor, a riser, a cyclone separator, an upper material returning valve, a regeneration reactor and a lower material returning valve, wherein the absorption reactor, the riser, the cyclone separator, the upper material returning valve, the regeneration reactor and the lower material returning valve are sequentially connected in a head-tail connection manner, and the lower material returning valve is communicated to the absorption reactor. According to the present invention, the solid-state amine dual fluidized bed reactor is established, and the continuous and stable operation is achieved; and the solid-state amine is used to continuously capture CO2, the capture efficiency achieves 84.4%, the capture efficiency is increased to 97% after a small amount of water vapor is introduced, and the performance of the absorbent maintains the stable state after the running.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a solid amine fluidized bed reactor. Background technique [0002] Global warming is mainly caused by CO 2 Mainly caused by a large amount of greenhouse gas emissions, for the control and reduction of CO 2 emissions, C0 2 Capture and storage technology has become a research hotspot in recent years. my country's energy consumption structure is dominated by coal, and CO emissions from coal combustion 2 About my country's CO 2 82% of the total emissions are mainly used for power generation. Therefore, the study on the removal of CO from flue gas of coal-fired power plants 2 technology is of great significance. In addition, CO 2 The separation is also commonly used in chemical processes such as synthetic ammonia, natural gas and biogas purification, spacecraft and ships and other confined spaces. Currently, all commercially captured CO 2 The current technologies are all ba...

Problems solved by technology

[0003] At present, the international research on solid amines mainly focuses on the research on materials such as the preparation and modification of absorbents to improve the absorption capacity. The research is mainly carried out on thermogravimetric analyzers and rarely involves research on reactors and system processes.

In terms of solid amine fluidized bed reactors, there are few reports in the literature

[0004] Therefore, the continuous capture of CO in solid amine reactors, especially in fluidized bed reactors, is currently 2 There is still a lack of research on

At present, domestic research on solid amines is mainly focused on the removal of CO in confined spaces such as spacecraft and submarines. 2 , there is not enough research on the decarburization of flue gas with solid amines
