Features

Albemarle’s H-PAC sorbent is a high-performance solution to mercury control challenges in systems with hot-side electrostatic precipitators and for injection upstream of the air preheater. H-PAC technology combines the proven bromination technology pioneered in our B-PACTM sorbents with advanced techniques for optimized performance at temperatures of up to 426°C. Hot-side ESPs have been proven to make mercury capture difficult with traditional activated carbon sorbents at temperatures above 204°C. Through extensive field trial and full scale site demonstration work, Albemarle is able to optimize the performance characteristics of H-PAC to achieve removal rates 70% with flue gas temperatures in excess of 371°C. H-PAC can also be used for injection on the hot side of air preheaters. Sorbent consumption can be significantly lowered by utilizing the intimate mixing of sorbent and flue gas through the air preheater. H-PAC is required to take maximum advantage of this configuration designed for high-temperture performance.

Handling Instructions

Wet activated carbon removes oxygen from air. In a partially closed, closed or confined space, oxygen levels may become depleted. If workers are to enter a vessel containing activated carbon, all applicable low-oxygen work rules and procedures should be followed, including all applicable Federal and State requirements.
