Pi-CO2 refers to a patented carbon capture process developed by Pi-Innovation. It's a novel approach that combines several key elements to improve the efficiency and effectiveness of carbon dioxide capture.
Key Features of the Pi-CO2 Process
Based on information from Pi-Innovation, the Pi-CO2 process integrates the following components:
-
Post-Combustion CO2 Capture: This means capturing CO2 from flue gases after the combustion process has already taken place.
-
In-Process Pre-Treatment: Crucially, before the CO2 capture itself, the process removes other pollutants such as:
- SOx (Sulfur oxides)
- NOx (Nitrogen oxides)
- Vaporized metals (e.g., mercury)
-
Heat and Compression Energy Recovery: The system is designed to recover energy in the form of heat and compression, improving overall energy efficiency.
Benefits of the Integrated Approach
The integrated nature of the Pi-CO2 process offers potential advantages compared to traditional CO2 capture methods. These advantages can include:
- Higher efficiency due to energy recovery.
- Lower operating costs as a result of pre-treatment reducing the load on the CO2 capture unit.
- Reduced emissions of other harmful pollutants (SOx, NOx, mercury) in addition to CO2.
In short, Pi-CO2 represents a potentially more efficient and comprehensive approach to carbon capture compared to existing technologies, addressing both CO2 and other pollutants while also incorporating energy recovery.
