Product Overview
This industrial flue gas CO₂ capture technology is designed for gas sources rich in carbon dioxide, such as lime kiln gas, cement kiln gas, glass furnace gas, flue gas, and fermentation gas. It enables efficient recovery of CO₂ from various industrial streams.
Depending on the gas composition, two core technologies are provided: low-partial-pressure CO₂ amine absorption and CO₂ pressure swing adsorption (PSA). These solutions can achieve CO₂ purity of over 99% or over 90%, with recovery rates of 70–90%, meeting the needs of industrial carbon capture and utilization.
Working Principle
Low Partial Pressure CO₂ Amine Absorption:
Designed for flue gas with CO₂ partial pressure of 8–15% (vol), this method uses a proprietary amine solution for selective absorption. After saturation, the solution is regenerated by heating to release CO₂. The process achieves a recovery rate of over 90%, with low energy consumption, minimal side reactions, and reduced equipment corrosion.
CO₂ Pressure Swing Adsorption (PSA):
This technology uses specialized adsorbents to separate and recover CO₂ through cyclic pressure changes. It can produce CO₂ with purity above 90% and recovery rates of 70–90%. The system offers low operating costs, high automation, long service life, and no secondary pollution.
Key Features
- Mature and Advanced Technology: Simple process design with stable and reliable operation.
