Product Overview
Chemical absorption CO₂ capture technology is a highly efficient solution for extracting and separating carbon dioxide from low-CO₂ concentration flue gas. The system integrates washing, absorption, desorption, compression, drying, cooling, and separation processes to ultimately convert CO₂ into a liquid form for storage and utilization, enabling flue gas emission reduction and resource recovery.
Working Principle
The technology is based on chemical absorption principles. Flue gas is first filtered through a wash tower, then enters the absorption tower, where CO₂ reacts with the absorbent to form soluble compounds. The CO₂ is subsequently released through high-temperature desorption, followed by compression, drying, and cooling to produce stable liquid CO₂.
- Hot Alkali Method: Suitable for high-temperature flue gas, offering fast reaction rates and strong absorption capacity.
- Amine Method: Optimized for low-temperature conditions and low CO₂ concentrations, ensuring efficient capture across diverse operating scenarios.
Key Features
- Streamlined Process: Combines washing, absorption, desorption, compression, drying, cooling, separation, and storage into an integrated workflow.
- Wide Applicability: Capable of handling low-CO₂ flue gas, suitable for power plants and combustion-based industrial emissions.
- Hot Alkali Advantages: Rapid reaction and strong absorption performance for high-temperature flue gases.
- Amine Advantages: Effective for low-temperature flue gas with low CO₂ content.
- High Efficiency: Coordinated operation of wash and absorption towers ensures effective flue gas cleaning, CO₂ absorption, and liquid CO₂ output.
Applications
- Power Plants: Capture low-concentration CO₂ emissions from coal-fired or gas-fired power generation processes for reduction and recovery.
- Combustion Industries: Applicable to boilers, furnaces, kilns, and other CO₂-emitting combustion processes.
