SCR for Recip Engines

Where permitted, units may be combined into a common HRSG and catalytic reactor.

HRSG coils are split to allow insertion of catalyst in the optimum temperature zone for maximum NOx conversion.

EnviroKinetics has developed unique solutions for exhaust NOx, CO, and hydrocarbon  control for IC engine installations of .5 to 6 MW with WHR.  These units can be prepped and onsite in as little as 12 weeks ready for service.   The mixing tube, SCR reactor, local control panel, and all instrumentation required to operate the system is integral to the skid.  All you have to do flange it up and you’re ready to power up.   Basic skid mounted combination unit with pyrolysis tube, oxidation catalyt, WHRU and SCR reactor with stack.

If the WHRU is required to load follow, a bypass with dampers may be required.  Catalyst for units like this is installed upstream of the WHRU where the temperature is more constant.

WHR coils can be built vertically and the pyrolysis tube can be made compact to minimize the unit's footprint.  NOx and CO catalysts are located in the optimum temperature range within the WHRU.

The optimum temperature for NOx catalyst and oxidation catalyst may not be the same.  The process temperature and conversion of each component enters into the decision of what kind of catalyst to supply and what temperature each catalyst will operate at.

Using state of the art modeling software, the entire WHRU is designed.  The computer model can then used to detail the final configuration of the WHRU.
