Description

Based on absorption formula carbon capture circulation application apparatus

Technical Field

The utility model relates to a carbon entrapment field, in particular to based on absorption formula carbon entrapment circulation application apparatus.

Background

Carbon capture, utilization and storage (CCUS) technology refers to a technical system for the long-term sequestration of CO2 from the atmosphere by separating and capturing carbon dioxide (CO 2) from industrial or energy production-related sources for geological, chemical, or biological use, or transportation to a suitable site for sequestration, a route that is considered to be an effective way to cut greenhouse gas emissions.

The chemical absorption method for removing CO2 is to utilize an alkaline absorbent to contact with flue gas and to chemically react with CO2 to form unstable salts, and the salts can be reversely decomposed under the condition of heating or decompression to release CO2 so as to regenerate the absorbent, thereby separating CO2 from the flue gas. The typical chemical absorption process is that the flue gas enters an absorption tower, flows from bottom to top, and forms countercurrent contact with an absorbent from top to bottom of the absorption tower, and the decarbonized flue gas is discharged from the top of the absorption tower. The absorbent for absorbing CO2 is rich liquid, the temperature of the absorbent is raised by a lean-rich liquid heat exchanger, the absorbent enters a regeneration tower to desorb CO2, and the desorbed CO2 and water vapor are cooled to remove moisture to obtain high-purity CO2 gas. The absorbent for desorbing CO2 is barren solution which flows out from the bottom of the regeneration tower, exchanges heat with the barren and rich solution heat exchanger, and enters the absorption tower to absorb CO 2. In the existing mode, flue gas directly enters the absorption tower from the bottom to be absorbed, and dust can be remained in the flue gas to influence the trapping result.
