Air quality control system
The plant uses a continuous emissions monitoring system (CEMS) to monitor nitrogen oxide (NOx), carbon dioxide (CO2) and dioxygen (O2) emissions. NOx emissions are controlled by using a selective catalytic reduction (SCR) system with aqueous ammonia injection.
Cooling system
A cooling tower is used to cool water coming into the plant. The cooling tower is a counter-flow, four-cell, forced-air unit, with two-speed axial flow fans. The source of water for the tower is from the City of Whitewater.
Control room
All major functions in the plant are controlled by operators with computer support to continuously monitor and report on pressures, temperatures, flow rates, etc. In addition, the computer aids in startup, shutdown, load adjustments and information for future reference. The plant control system uses Emerson Ovation technology for plant functions.
Safety
The facility has safety and monitoring features that minimize risks to the public and meet federal, state, local and industry standards.
