Project description
Rotating packed beds can enhance post-combustion CO2 capture
Rotating packed beds (RPBs) have gained increasing attention recently for their potential in process intensification. RPBs rely on centrifugal force to increase the contact of different phases such as liquid-solid or liquid-gas, thus enhancing mass transfer between the two. In the case of post-combustion CO2 capture from flue gases, this also enables a reduction in absorber and desorber sizes. The EU-funded HiRECORD project will demonstrate the high-tech readiness of a modular CO2 capture plant comprising a RPB absorber and advanced RPB desorber with integrated spinning reboiler and advanced, greener solvent. The system will cut CO2 capture costs in half compared to conventional technologies while significantly lowering the environmental and safety impacts.
Objective
In a world’s first, HiRECORD will demonstrate at TRL 6, a modular CO2 capture plant that will comprise a Rotating Packed Bed (RPB) absorber and an advanced RPB desorber with integrated spinning reboiler (RPB-ISR). The plant will be of 10 t/d CO2 capture capacity and will operate with the advanced, APBS-CDRMax solvent. It will be operated on the premises of a natural-gas power plant (ELPEDISON), of an industrial gas boiler (TOTAL ENERGIES ONE TECH) and of a quicklime plant (CAO Hellas), highlighting the high modularity and flexibility of RPB processes with flue gases of different specifications. The advanced capture plant will allow up to 50% capture cost reduction, compared to conventional MEA-based, packed-bed technologies. This reduction will result from at least 10 times lower space footprint due to the use of the RPBs, with direct beneficial impacts on capital expenditures, as well as a regeneration energy of 2.0-2.1 GJ/tCO2 due to the use of the APBS-CDRMax solvent and the RPB-ISR. These features will also enable 20% and 50% lower environmental and safety impacts, as the solvent and operating conditions will minimize emissions, corrosion and make-up requirements. Techno-economic studies will also include an industrial cluster in Northern Greece, where options of CO2 utilization as well transportation and sequestration in nearby geological sites will also be investigated. Extensive societal, public acceptance and policy studies will also be performed, including surveys to the over 750 members of the industrial association partner SEVE.
