The innovation represents a BIAS particle sorbent suspended in a non-aqueous fluid carrier (slurry) that is capable of CO2 sorption, is easy to incorporate into established power plants, and can minimize energy and infrastructure requirements.
Carbon sequestration can reduce the emissions of CO2 from large point sources and holds potential to provide deep reductions in greenhouse gas emissions. Amine-based solid sorbents are effective and economical agents for CO2 capture from gaseous mixtures. However, because of the high concentration of CO2 in many feed streams, a large quantity of the gas often reacts with the sorbent exothermically to produce excessive heat, which must be removed from the sorbent to prevent temperature instability within the reactor and to eliminate potential degradation of the sorbent. Reducing the damage to sorbents with this technology and method can increase efficiency and reduce replacement costs faced by industries.
