An Introduction to CO2 Separation and Capture Technologies

3 The flue gas approaches in use today require clean-up of the NO x and SO 2 prior to CO 2 separation. The oxygen route does not. If the sinks are tolerant to NO x and SO 2, we can eliminate separate control steps and sequester the NO x and SO 2 along with the CO 2, resulting in a zero emissions power plant.

Selective Catalytic Reduction (SCR) For Boilers

Keeping this in mind, the specific catalyst manufacturer will determine the desired range. Secondly, watertube boilers are better suited for SCR systems than firetube boilers. The reason for this is attributed to the flue gas temperature ranges and expected NOX output. However, both boilers can benefit from an SCR system when properly designed.
