RTI International is partnering with Creare to design, fabricate, and test, at bench scale, a contactor coated with advanced solid sorbents for direct air capture (DAC) of carbon dioxide (CO2). The project is focused on the operation of a bench-scale CO2 removal unit inside an environmental chamber that will maintain constant, controlled test conditions for long-duration life testing (e.g., 1,000 cycles) and parametric testing.
