A cryogenic carbon capture process developed by BYU chemical engineering professor Larry Baxter removes more than 90 percent of CO2 from industrial plant emissions by freezing the CO2 and then storing it rather than allowing it to be released into the atmosphere. The frozen CO2, which is dry ice, can be separated out from other gasses and then converted back to a liquid for long term storage and potential use in other processes. The cryogenic carbon capture process also makes it possible to remove other pollutants including nitrogen oxides, sulfur oxides and mercury. The new technology, which is being commercialized by Sustainable Energy Solutions in Orem, Utah, promises significant reductions in CO2 and other pollutants at a lower cost than other carbon capture technologies.
