Air Pollution Control
As the call for sustainability increases, both green house gases and particulate matter need to decrease. Regulatory agencies are aggressively implementing and monitoring flue emissions - from energy generating boiler systems - to keep the air clean and the earth healthy. Since Ashland composites resist corrosion, they can help reduce costly maintenance charges while, at the same time, keeping scrubbers and liners working to help you avoid regulatory fines. Working with Ashland composites lets you breathe easy knowing your sophisticated (and expensive) scrubbers and air pollution control systems are protected against damaging (and expensive) corrosion.
Regulatory agencies continually update standards, raising the bar ever higher for air pollution control. This creates a challenging situation for plant managers and owners to install and maintain sophisticated scrubbing equipment for flue gases emitted by energy generating boiler systems. These emissions create a highly corrosive environment for both stainless steel and nickel alloys that are often used in air pollution control processes. The combination of low maintenance and exceptional performance and durabiity in corrosion prone environments, Derakane™ and Hetron™ fiber-reinforced plastic (FRP) composites made with epoxy vinyl ester resins, from Ashland, have quickly become the material of choice for many applications in air pollution control equipment.
Ashland Derakane™ and Hetron™ epoxy vinyl ester resins are commonly found in:
- Coal-fired power plants, where their superior abrasion and corrosion resistance, protect scrubbers, piping and ducting
- Highly corrosive environments with hot, wet, acidic gases
- Water processing tanks and piping with extremely hot processing water
- Cooling towers and pultruded structural profiles and fan shrouds
From one chemical company to another
As a chemical company, Ashland has first hand knowledge of the damage, cost and havoc that corrosion can create on sensitive chemical processing equipment and facilities. We put our money where our mouth is and use our own corrosion resistant fiber reinforced plastic resins to protect systems. Utilizing Ashland composite materials to reduce corrosion helps increase the lifecyle of equipment, thereby reducing maintenance and replacement costs. Useable, low maintenance, cost efficient and effective - we want to the offer the solutions we use for ourselves, to you.
First invented by chemical companies searching for chemical resistant materials for their aggressive processes, fiber-reinforced plastic (FRP) resins, such as Hetron™ and Derakane™ resins from Ashland offer protection in a variety of applications. Hetron™ chlorendic polyester resins can replace the high nickel alloys often used in the piping and headers found in chlor alkali production units. Derakane epoxy vinyl ester resins replace metal alloys in an array of chemical processing plants including those that manufacture chlorine and caustic.
Chemical processing facilities around the world are replacing corrosion prone and high maintenance materials such as carbon steel, stainless steel and masonry with high performance, low maintenance and long lasting FRP materials.
Fiber reinforced plastic resin also offers significant cost savings over more traditional materials such as stainless steel. Even in harsh environments that have traditionally used Hastelloy or titanium, FRP resins are a more economical choice. The engineering team at Ashland conducted research to determine the relative cost of a variety of common storage vessels and the results showed that FRP is about 1/4 the cost of some traditional materials.
Mining for minerals and solutions
The acids, extremely high temperatures, and acid chlorides that make mineral processing possible; also pose threats - in the way of corrosion - to the same systems. Fiber reinforced plastic resins protect tanks, scrubbers, pipes and more to keep your minerals process moving along smoothly. Ashland mines the best of the best to bring you the best in solutions for corrosive prone environments.
With the ability to withstand extremely high temperatures (90°C) as well as the harsh acids and acid chlorides used in mineral processing facilities, fiber-reinforced plastic resins are rapidly replacing traditional and expensive metal materials.
Cost-effective Derakane™ epoxy vinyl esters offer unsurpassed durability for component construction including:
- storage and processing vessles
Pulp and Paper
Sheaves of solutions
Acids, alkalies, and bleaches are the common ingredients used to convert wood into wood pulp and then ultimately, into paper. As solvers, we are always capturing our thoughts and ideas for market-driven solutions and innovations. Our solutions include fiber-reinforce plastic (FPR) resins that provide a cost-effective alternative in corrosion prone environments like pulp and paper mills. We don't think you need reams of solutions - just one that meets your needs and provides some additional benefits like lower maintenance costs and extended useful life of equipment.
Proven solutions for highly aggressive environments
The world relies on paper, yet for paper manufacturers, never has there been a greater need to rely on a partner who can balance the call for innovation and quality with reduced operating costs. Processing wood to paper requires the use of highly corrosive chemicals such as acids, alkalies, bleaches and salt. Throughout the mill, this requires specially designed and expensive processing equipment that can withstand a variety of harsh chemical environments.
In pulp mills throughout the world, fiber-reinforced plastic (FRP) equipment fabricated from Derakane™ epoxy vinyl ester resins have proven to be an exceptionally cost-effective, corrosion-resistant alternative for process fluid environments where conventional metals and coatings quickly fail. Combined with fiberglass reinforcement, Derakane epoxy vinyl ester resins can be fabricated into corrosion-resistant lightweight piping, ductwork, tanks, hoods, scrubbers, and stacks –- for far less than the cost of stainless steel several times lower cost than exotic alloys.
Superior Chemical Resistance
Derakane™ resins can resist a variety of corrosive chemicals encountered in a pulp and paper mill, at both ambient and elevated temperatures. Unlike metals, Derakane™ resins are unaffected by chloride stress or crevice corrosion and are highly resistant to pH extremes. With FRP equipment, there is no need to worry about long-term corrosive effects of continued closing of the recovery loop or about wide variations in pH levels during the bleaching process.
