The CDRMax® Process
The CDRMax® licensed process captures carbon dioxide (CO2) from industrial flue gases or off-gases emitted from power plants, boilers, and chemical facilities. The technology removes from 50 to 95% of the CO2 from natural gas, coal, and petroleum-fired processes to produce a high purity (>99.5%) industrial grade CO2 for downstream use. The process is applicable from mid-scale (100s of metric tons per day) to large-scale (1,000s of metric tons per day) capacities for carbon capture and utilization (CCU) projects which can be integrated with materials, chemicals, and energy production
Technology Benefits
CDRMax® operates at atmospheric pressure to capture and purify CO2 from low pressure flue gas and off-gas streams. The technology can be flexed to manage CO2 concentrations in the source gas from 3% to 25% and produce CO2 with purities between 95-99.99%. CDRMax® is a proven chemical absorption-based process technology that combines the use of an advanced proprietary solvent with novel heat integration to reduce the cost of capture to an estimated $40 (USD) per metric ton, a 40% life-cycle cost reduction versus* conventional CO2 capture technologies.
Reduced Life-Cycle Costs
Our CDRMax® process captures more CO2 with less hardware and lower utility costs. CAPEX drops by 25% and OPEX by 40% when compared to conventional MEA-based absorption. Our proprietary solvent:
- Increases CO2 loading to reduce pump sizing & circulation
- Reduces heat/power duties by 25-45%
- Minimizes corrosion thereby extending equipment life
- Requires no anti-foaming and anti-corrosion additives
- Keeps working — resists solvent degradation and foaming
- Lowers solvent emissions and waste-disposal costs
For either greenfield plants or as drop-in replacements at brownfield sites, our advanced solvents will reduce costs and extend plant life without equipment changes.
Working Principles (Refer to Process Flow Diagram below.)
Flue Gas Conditioning – Flue gas is conditioned by an SOx/NOx scrubber (1) and then cooled (2).
Absorption – The conditioned gas enters an absorption column where it contacts the counter-current flow of our proprietary solvent for efficient CO2 absorption.
Washing – The depleted flue gas exits the absorber column and passes through an integrated water washer (3) to minimize the loss of the solvent.
Stripping – The CO2 rich solvent from the absorber bottom flows to the lean/rich heat exchanger (4), where the rich solvent is heated before entering the stripper column. The lean solvent (low CO2) flows to the reboiler, where it is heated by auxiliary steam (5). The steam from the reboiler enters the stripper tower (6) flowing upward, counter-current to the rich solution. The absorbed CO2 is released from the rich solvent and flows to the top of the stripper tower (7). The lean solvent is returned to the absorber column via the lean/rich heat exchanger for further flue gas processing. The 95-99.99% purity CO2 is directed to the end-use application. (8)
