deHg and deSOx : GORE™ Mercury and SO2 Control System
W. L. Gore & Associates G.K.
Technology / Service Summary
GORE Mercury Control System provides both high efficiency and a high capacity for removing elemental and oxidized mercury from flue gas streams, and reduces SO2 concentrations.
Purpose
for Hg and SOx reduction
Feature
The modules are simple and cost-effective to operate, with no moving parts, no chemicals to manage and a long lifetime.
Modules can be stacked to achieve the desired level of mercury removal requirements.
Based on a novel Sorbent Polymer Composite (SPC) material developed by Gore, it provides both high efficiency and a high capacity for removing elemental and oxidized mercury from flue gas streams.
In addition, it also reduces SO2 concentrations.
Due to the unique chemistry employed, the SPC material is insensitive to process or material changes that impact mercury speciation and to common sorbent "poisons" such as SO3 and VOCs.
This allows it to continually reduce mercury and SO2 concentrations in a gas stream for long periods of time before needing replacement.
Effect
# Remove both elemental and oxidized mercury at 1 system
→ no need to oxidize mercury before GORE system (= no SCR)
# Simultaneously remove SO2 and Hg
→ no need to consider reagent or install FGD
# Very low operating cost
→ no reagent, no complicated system, passive operation system

Accomplishments
GORE Mercury Control Systems are currently in operation in five absorbers in the coal-fired power industry. Several more are currently under construction for start-up in early 2016, at which point the installed operating capacity will exceed 2100 MW.
Including full-scale and slip stream pilot experience, GMCS Modules have successfully operated on flue gas from power plants burning all types of coal: high and low sulfur bituminous, PRB, and lignite.
