Temperature control and gas conditioning through evaporative cooling, condensing, and heat transfer.
EXUS’S 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.
Quench Towers & Condensers
EXUS’S 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 EXUS engineers.
Vertical Quench Tower
A traditional vertical quench tower is the most common and widely accepted quench design. It is often similar in dimension and footprint to the downstream wet scrubber despite their operational differences. The incoming gas stream usually enters at the top of the tower and exits at the bottom or the side of the unit. Nozzles and spray patterns may operate in a co-current or counter-current mode depending on application specifics.
The vertical quench tower typically uses the recirculated scrubbing liquor and/or fresh water to evaporate moisture and cool the incoming gas. An emergency fresh water feed is usually recommended in the event of primary nozzle plugging or pump failure.
