A fully automated carbon dioxide capture pilot unit has been developed for tests on flue-gas slip streams from coal-fired power plants. This process involves a packed-bed sorbent system undergoing two-stage cycles: low-pressure adsorption and steam-aided vacuum regeneration. Early laboratory experiments confirm that 90% recovery and 95% CO2 purity are attainable in a single adsorption/desorption cycle. Field tests are planned this summer to demonstrate that these goals are attainable for over 100 cycles. Following the field tests, economic analysis will be performed to quantify the overall cost per ton of captured CO2 and compare it with alternative CO2 capture technologies.
