Portable gas scrubbers are used to neutralize corrosive exhaust gas from reactors. They are also used for scale-up studies by stripping the exhaust of the substance (often HCL) to be absorbed in the absorption column. Depending on the scrubbing liquid, they can be used for caustic or acidic vapors. Gas scrubbers are equipped with an ETFE lined, corrosion resistant magnetic coupled pump. The maximum flow rate can be controlled with the built in reducing valve. The scrubbing liquid temperature can be easily maintained in the optimal range through the spiral cooler.
