The GORE SO2 Control System is a flue gas desulphurization system (FGD) which allows plants to comply with SO2 emission standards without requiring any reagent. The system utilizes fixed catalysts to convert SO2 into saleable sulfuric acid. This eliminates concerns related to reagent supply, logistics, handling, storage and preparation operations, reagent price volatility and solid waste disposal. Since the Gore System is installed after an existing ESP or baghouse there is no impact on the fly ash, allowing for its continued beneficial use.

The science behind the solution
How GORE SO2 Control Modules work
Sorbent Polymer Catalyst (SPC) composite material is a novel fluoropolymer-based substance created by Gore scientists. This substance's sorbent effectively captures both elemental and oxidized mercury from the flue gas stream. As a result, it is unaffected by modifications to fuel or manufacturing processes that alter mercury speciation. Through chemisorption, mercury is tightly bound inside the SPC. It is a highly successful solution for high sulfur coals or units with SO3 gas conditioning because, unlike many activated carbon sorbents, the presence of SO3 does not prevent mercury extraction by the SPC. Since no injected sorbents are used, there is no need to worry about fly ash contamination or additional particulate matter collection. Additionally, the technology eliminates the need for chemicals for oxidation, thus avoiding concerns over halogen-induced corrosion and wastewater treatment complications.
GORE SO2 Control System including water quench, catalytic modules & acid collection
The lack of reagent and low parasitic power enable a significantly lower operating cost than other Flue Gas Desulphurization (FGD) systems. Moreover, the footprint of the system has significant flexibility allowing it to fit into space constrained sites that are challenging for wet and semi-dry systems. In addition to lower water consumption, the passive system operation is simple and doesn’t require any adjustments, treatments, or regeneration. The catalytic SPC modules have no moving parts and will continuously convert SO2 into sulfuric acid for many years with the lowest total cost of ownership.
The sulfuric acid byproduct is a versatile chemical with strong demand in the fertilizer production industry. Unlike limestone-based FGD systems, the GORE SO2 Control System does not produce additional CO2.

Hindalco has awarded a contract to W.L. Gore for FGD control with its Sorbent Polymer Catalyst technology at the Renusagar Site for an 80MW unit. The GORE® SO2 Control System is a catalytic, reagent-less FGD system designed to fit tight spaces, consume less water, and reduce operating costs.
CEZ Group Turns to Gore to Reduce Mercury Emissions from their Mělník I Power Plant in the Czech Republic
Posted July 23, 2019
New EU regulations limiting mercury and SO2 emissions are due to come into force by 2021, and for operators of coal-fired power plants, it’s time to act. A proven, reliable and low cost technology to reduce emissions is needed to meet current and future regulations and to minimize negative environmental impact. An innovative system made by Gore is providing the solution.

The GORE Mercury Control System (GMCS) is a unique fixed sorbent system for capturing elemental and oxidized gas phase mercury from industrial flue gas. The system is based on discrete stackable modules that are installed in an existing flue gas cleaning system. Stop by our Booth #6 to find out why our 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.
