Powder Activated Carbon (PAC) system Integration

Powder Activated Carbon (PAC) system Integration

March 3, 2011

Ready integrated carbon injection and mercury analyzer systems into existing multi-unit, coal fired power generation facilities to meet legislated mercury abatement deadlines. The work involved utilizing a combination of serial Modbus and Modbus TCP communication protocols through various gateway hardware, as well as developing PCV graphics and tag databases, and programming logic across MFP02 and BRC400 controllers. The primary development tools were ABB GPI version 3, ABB Composer 5, and various gateway vendor packages, with the final solution being deployed into legacy DAS and CEMS systems running the Bailey PCV HMI, and ABB Infi-90 controls.

Further work will be ongoing to optimize the mercury abatement systems by implementing more advanced control strategies.
