CATACARB Process

The CATACARB Process is an advanced hot potassium carbonate (HPC) technology for carbon dioxide (CO2) capture. It uses a solution of potassium carbonate dissolved in water to chemically absorb CO2 under pressure in an absorption tower. The CO2-rich solution is then sent to a stripping tower where it is regenerated using steam to release the captured CO2. 

Key features of the CATACARB Process include:

- Ability to capture 99.9% pure CO2 without modifying upstream processes
- Use of proprietary inorganic catalysts that improve CO2 absorption and stripping efficiencies by over 40% compared to basic HPC
- Non-volatile, non-degradable solution that eliminates need for continuous makeup (typically <10% per year)
- Environmentally friendly compared to amine processes, with no organic emissions
- Flexibility to replace up to 80% of heat requirements with electrical demand
- Over 60 years of continuous improvement and optimization

The process can be customized for specific applications and has been deployed in over 200 commercial plants across industries like power generation, steel, cement, and petrochemicals. It can handle CO2 capture rates from 1 to over 10,000 tonnes per day, with capture efficiencies of 90-95%. The system energy requirement ranges from 0.7-1.8 GJ/tonne of CO2 captured.

CATACARB touts the process as an efficient, reliable and environmentally responsible method for large-scale CO2 capture, leveraging decades of operational experience to optimize designs.
