Inputs for configuring the Syngas cleanup technology are entered on the Config parameter screen. All of the parameters on this screen are currently read-only. The following parameters are shown for reference:

•Water Gas Shift (WGS) Reactors:

•Number of WGS Reactors (integer): This parameter defines the number of WGS reactors.

•Number of WGS Internal Coolers (integer): This parameter defines the number of WGS internal coolers called low-pressure (LP) steam generators 1 and 2. They are used to produce LP steam for CO2 regeneration while reducing the temperature of the syngas entering the WGS reactors.

•CO Conversion Rate in Each Reactor (fraction): This parameter defines the molar CO conversion rate of the WGS reactor.

•MDEA CO2 Capture System:

•System Used: The type of chemical solvent CO2 absorption technology used. MDEA is currently the only option.

•Absorber CO2 Removal Efficiency: This is the actual removal efficiency of the MDEA absorber alone. It it currently fixed at 95%.

•Number of operating Absorbers: This is the total number of operating absorber vessels.

•AGR Precooler Used?: An Acid Gas Removal (AGR) precooler is configured by default to cool the syngas before it enters the amine system and removes the excess water from the syngas.

•AGR Precooler Outlet Temp.: This is the temperature exiting the AGR precooler and entering the absorber.
