Rotamix (SNCR) NA X Yes Rotamix control systems have been
demonstrated on small coal-fired
boilers. However, there are several
currently unresolved technical
difficulties associated with
applying SNCR-type systems on a
large subbituminous coal-fired
boiler. Therefore, Rotamix is not
considered an available retrofit
control technology for Muskogee
Units 4 & 5.
Pahlman Process NA X No Bench- and pilot-scale testing has
been conducted on coal-fired
boilers, however, there is limited
data available assessing the
technical feasibility of this system
on large coal-fired boilers.
Wet NOx Scrubbing NA X Yes The system has been used on
refinery fluid catalytic cracking
units and small coal-fired boilers,
but has not been used on large
coal-fired boilers. Wet NOx
scrubbing systems are not
commercially available or
technically feasible for Muskogee
Units 4 & 5.
