High Temperature Quench

High Temperature Quench

High temperature quench systems are used when the inlet process is hot and must be cooled prior to entering a wet scrubber. Inlet temperatures may vary from 300 – 2000 °F and will require a quenching system prior to scrubbing the acid gases and other contaminants.

Material of construction may vary between stainless steel, alloy 20, titanium, alloy 2205 or Hastelloy C276 depending on the corrosive environment and operating temperatures. In most cases the quench orientation is vertical downflow but may be installed in a horizontal flow orientation for some low temperature applications.

Our standard quench systems operate at ambient pressure and adiabatically cool the process gas by evaporating water until the gas stream approached its saturation / wet bulb temperature.

The key parameters required for properly sizing a quench / cooler system include the following:

1.  Inlet Temperature
2.  Water Vapor Content
3.  Ventilation Rate
4.  Particulate Loading
5.  Removal Efficiency
6.  Corrosion Resistant Materials to handle elevated temperatures

The scope of supply for a high temperature quench system generally include but not be limited to an alloy quench vessel, remote sump, recycle pumps and piping, electrical control panel, and instrumentation.
