The CATACARB® Process, which is a modified Hot Potassium Carbonate (HPC) CO2 removal process, has been proven across a wide array of gas treating applications over the past 60 years. A diverse set of applications has brought on an equally diverse set of problems and considerations which have manifested over tens of millions of cumulative operating hours. Given the chemistry and physical properties of many gases under consideration for carbon capture (e.g., flue gas), applying HPC for CCUS poses no novel considerations (e.g., NOx/SOx, particulate matter, etc.) and can be applied today with extreme confidence. This allows the HPC specialists behind the CATACARB® Process to solve the 21st Century carbon capture problems with time-tested solutions.
