Multipollutant Control Pilot Testing

Southern Research is located in close proximity to four advanced pilot test facilities owned by Southern Company Services, Inc. As a benefit to our clients, these four separate test facilities are available to Southern Research scientists and engineers for research and testing of multi-pollutant control methods.

COHPAC I^® Pilot Test Facility

• 5,000 acfm flow rate, single speed fan
• Fabric filter test facility with 5 x 5 array of pulse-jet filter bags
• Filter bags - nominal 6" diameter x 16' length
• Accommodates filter bags up to 24' in length
• Intermediate pressure cleaning currently installed (40 psi)
• Flow control capability with butterfly outlet damper
• Venturi for low rate monitoring and control (if desired)
• Mixed flue gases from upstream and downstream of air heater provide range of inlet flue gas temperature (automatically controlled)
• Inlet flue gases can be pulled from the Unit 2 ESP for COHPAC I^® and TOXECON^® simulations
• Integrated dry sorbent injection skid available

COHPAC II^® (ESP) Pilot Test Facility

• 5,000 acfm flow rate with VSD fan
• Two field ESP followed by compartmentalized baghouse test section
• Baghouse test section - 4 x 3 array of 6" diameter by 8' long filter bags
• Pulse-jet cleaning (air pressures up to 100 psi)
• Manual mixing of air heater inlet and outlet (Miller Unit 3 inlet) flue gases available for control of pilot inlet flue gas temperature
• Inlet and outlet test ports available
• Control room trailer adjacent to pilot
• Trailer houses ESP AVCs and pilot control and data logging hardware

SCR de-NOx Pilot Test Facility

• Located adjacent to Plant Gorgas Unit 8
• Takes and returns flue gas upstream of Unit 8 air heater
• In-duct heaters maintain 650°F module inlet temperature
• Pilot has three 400-scfm test modules
• Each module has a dummy layer followed by two active catalyst modules
• Each bed holds a single 13" x 13" x 1m catalyst module
• Flow rate can be independently controlled through each module
• Each module has a bypass duct
• Temperatures and pressures are monitored throughout
• Ammonia is injected in the inlet duct before the split
• Control and data logging system recently updated
