Regulatory agencies are aggressively implementing air pollution control (APC) standards, which require sophisticated scrubbing equipment for flue gases emitted by energy generating boiler systems. The environment in these air pollution control systems is highly corrosive to stainless steel and even higher nickel alloys. As a result, fiber-reinforced plastic (FRP) composites made from epoxy vinyl ester resins have become the preferred material of construction in many facets of air pollution control equipment from a performance perspective.
- FRP scrubbers, piping and ducting made from DerakaneTM epoxy vinyl ester resins are commonly found in equipment used to scrub air pollutants from coal-fired power plants. FRP scrubbers, tanks and slurry piping made with these resins provide superior abrasion and corrosion resistance.
- Ducting, stack liners and demister blades made with Derakane resins provide superior corrosion resistance to hot, wet acidic gases.
- Process water tanks and piping often use these resins due to their compatibility with hot process water.
- Cooling towers frequently specify Ashland AropolTM resins for use in pultruded structural profiles and fan shrouds due to their high durability and low maintenance requirements.
Ashland corrosion resistant resins have been specified for more than 60 years for FRP process equipment used throughout these industries. We strongly believe in this technology and use it in our own chemical processing facilities around the globe.
