Development of a Novel Gas Pressurized Stripping Process-Based Technology for CO2 Capture
Project No.: DE-FE0007567
Carbon Capture Scientific is developing and testing a novel, proprietary, Gas Pressurized Stripping (GPS) process-based technology for CO2 capture from post-combustion flue gases. GPS process-based technology has many advantages. For the solvent based process it will be able to:
- Reduce the energy penalty associated with solvent regeneration
- Increase the CO2 desorption pressure
- Integrate CO2 capture and compression into one step
- Reduce CO2 compression needs
- Reduce solvent degradation
These advantages could potentially eliminate CO2 compression entirely, hence reducing the total parasitic power load of a CO2 capture process to about 0.14kWh/kgCO2. This power load is a 60 percent reduction compared to the baseline case of 0.38kWh/kgCO2. The economic impact of this parasitic power reduction is a reduction in the incremental cost of electricity (COE) by about 21 mills/kWh.
The objectives of the project are:
- Perform bench-scale tests of individual process units to document experimental results and obtain necessary information to progress the technology to pilot scale
- Use computer simulations to predict the GPS column performance under different operating conditions, thereby optimizing column design and operating conditions
- Validate the use of a typical commercial solvents system in the GPS process to insure that is can perform efficiently under process conditions
