Why a Process Monitor is
Necessary?
Mercury Process
Monitor
• Pair a process monitor with sorbent traps
to see what your compliance data (sorbent
traps) are seeing in real-time
• Fine-tune control technology injections
without overpaying for them
• Prevent an unknown increase in mercury
emissions from putting you out of
compliance
• Monitor FGD performance and correlate
changes to emissions changes
915 J Mercury Process Monitor
• Process Monitor will be an
essential tool as new control
technologies arise in the future
• Minimal maintenance and
down-time will be key to
success of process monitor
