Selection of Powdered Activated Carbon for EPA MATS Compliance

Many in the electric generating industry see powdered activated carbon (PAC) for mercury control as a commodity product where in fact incorrect carbon selection could make a difference in your yearly activated carbon costs of several hundred thousands of dollars per year. PACs are different and where they are injected in your power plant can impact their effectiveness and thus yearly costs for compliance. Therefore PAC selection should be based on more than solely cost per pound. This discussion will be based on but not limited to your plant’s coal type, air pollution control devices (existing and planned installations to comply with EPA regulations), fly ash and other by-product salability, and your plant’s overall operations and disposal requirements.  Furthermore, activated carbon manufacturing and its properties will be reviewed.
