This is a standard capital cost result screen. The chemical looping system has the following process areas:

Carbonator: The carbonator converts CaO and CO2 to CaCO3, thereby reducing the concentration of CO2 in the flue gas.

Calciner: The calciner converts CaCO3 to CaO and CO2. The CO2 is sent to storage.

ASU: The Air Separation Unit (ASU) provides pure oxygen to the calciner.

Blowers: Blowers are used to offset pressure drops in both the calciner and the carbonator.

CO2 Product Compressor: The product CO2 must be separated from the water vapor (dried) and compressed to liquid form in order to transport it over long distances. The multi-stage compression unit with inter-stage cooling and drying yields a final CO2 product at the nominal pressure of 2000 psig. This area is a function of the CO2 flow rate.

CO2 Purification Unit: The product CO2 is purified before being compressed.

Coal Handling Equipment for ASU: This is the coal handling equipment used by the Air Separation Unit (ASU).

Solids Handling Equipment: This is the solids handling equipment for the calciner and carbonator.

Steam Turbine for Power Generation: A steam turbine is used to generate power for the chemical looping system.
