| Abstract Scope |
Carbon capture in steel industry remains challenging due to the prohibitively cost and low efficiency introduced by large adsorption bed sizes used in current commercial carbon capture process. Funded by DOE, this effort led by Molecule Works Inc and Advanced Manufacturing LLC has demonstrated the feasibility to lower operation cost to $100/ton of carbon capture by quick removal of heat of adsorption and supply of heat for desorption. A novel adsorptive heat exchanger (AHX) unit has been designed and fabricated for low-cost, energy-efficient CO2 capture. The unit is composed by repetitive cassettes consisting of adsorbent powder held sandwiched within thin microporous metal membrane (30-60µm thick) and a thin dense metal foil. The innovative design allows for the use of any adsorbent powder without complex particle- specific material processing. The technology would help reduce CO2 emissions in the US steel industry with its low cost and high efficiency. |
