Albemarle is the Total Solutions Provider for Mercury Control
Albemarle is the largest U.S. bromine producer and one of the world’s leading suppliers of bromine and bromine-based products. Albemarle’s Mercury Control Division supplies proprietary gas-phased brominated powdered activated carbon (PAC) sorbents, non-brominated PAC sorbents and bromine chemicals, as well as custom-designed Sorbent Injection Systems and full-scale trial capabilities.
Albemarle pioneered the development of gas-phase brominated powdered activated carbon (PAC) mercury sorbents and has a variety of products that offer low cost, proven mercury control to our customers.
B-PAC is for use in facilities equipped with cold-side electrostatic precipitators (CS-ESP) or fabric filters for particulate control. B-PAC has been shown to have superior mercury removal performance to salt-impregnated PACs and, thus, to be more cost effective.
C-PAC, a concrete-friendly temperature sensitive sorbent, is for use in boilers that require high levels of mercury removal but desired to maintain fly ash sales for use in cement. C-PAC provides the same high mercury removal rate as our other gas-phase brominated mercury sorbents, but also has a minimal impact upon the air entrainment additives (AEAs) used to form bubbles in concrete.
H-PAC is a mercury sorbent that is temperature insensitive at temperatures over 800°F. Plain PAC and salt-impregnated PACs can begin to lose their mercury capture ability at temperatures as low as 300°F. Gas-phase bromination is the key to the temperature insensitivity, since bromine resists the impact of flue gas oxygen.
