Quench Towers & Condensers

Temperature control and gas conditioning through evaporative cooling, condensing, and heat transfer

Temperature control and gas conditioning through evaporative cooling, condensing, and heat transfer

Application or technical questions?

Monroe Environmental Quench Towers and Condensers provide temperature reduction and control of hot process gasses through evaporative cooling, condensing, and a variety of heat transfer methods. A Quench Tower or Condenser is often the first step in conditioning a high temperature, polluted air stream so that particulate, acid gasses, metals, and other emissions can be adequately removed. Quench Towers and Condensers are often used following thermal treatment systems such as incinerators, reactors, kilns, boilers, furnaces, oxidizers, and other process systems that produce contaminated gas streams at elevated temperatures.

Monroe Quench Towers & Condensers

Monroe Environmental engineers have the experience to provide a customized Quench Tower design that will meet the needs of your application without the use of excessive water consumption. Using the air temperature and moisture content (lb. water per lb. of dry air), the temperature at full saturation can be predicted. Systems which require only partial saturation to meet specific temperature targets can also be designed by Monroe engineers.

Spray Quench Tower Design

Fabrication of a Spray Quench Tower for high temperature scrubbing applications

The proper design of a Quench Tower takes into account many factors, including:

  • Inlet temperature
  • Inlet moisture content
  • Target temperature
  • Target moisture content
  • Effect of quenching on particulate formation and control
  • Chemicals present is air/gas stream
  • Velocity of the gas stream and gas retention time
  • Nozzle design and spray patterns
  • Materials of construction to withstand temperature and chemical attack
  • And many others

Monroe Environmental can assess these and other application factors and custom design a quench tower that is suitable for your application.

Quench Materials of Construction

The materials of construction are especially important as they must be selected to both withstand attack from the various pollutants contained within the airstream and be resistant to high incoming temperatures. Common materials of construction include:

  • Hastelloy
  • AL6XN steel
  • Duplex stainless steel
  • 304 and 316 stainless steel
  • Refractory and ceramic linings
  • Other specialty alloys
