Methods and technologies for carbon dioxide capture and separation in power plants and the proposal of optimal integration of carbon dioxide capture technology into the process technology of the power plant

  • Research and development of the optimal concept of CO2 capture by post-combustion method (capture from flue gas after fossil fuel combustion); Technical design of a CO2 absorption capture system from flue gas and optimal integration of the system into the process of power generation with regards to the specified power output and fuel; Evaluation of impacts of integration of the capture system on the operational costs and price of electricity;
  • Research of post-combustion technology:
    • ammonia absorption,
    • low-temperature adsorption on solid sorbents,
    • high-temperature sorption on CaO (so-called carbonate loop);
  • Research and development of the optimal concept of CO2 capture by the oxyfuel method (pure oxygen combustion); Design of an oxygen burning boiler for the specified power output and fuel; Evaluation of operational costs of a power station with oxyfuel combustion and capture of CO2;
  • Research and development of the optimal concept of CO2 capture by pre-combustion method (coal gasification and subsequent capture from synthesis gas); Design of a technical system consisting of integrated coal gasification, treatment, purification and separation of CO2 from synthesis gas and subsequent use of gas in a combined cycle for energy generation, with regards to the specified power output and fuel; Evaluation of operational costs and price of electricity;
  • Experimental research equipment:
    • Test unit for research of a low-temperature sorption of CO2 from real flue gas located at the Prunéřov power plant;
    • Test unit for research of a high-temperature sorption at the pressure up to 2.5 MPa.
