Depending on the scrubbing liquid used and the gas contaminants involved, the liquid will absorb or react with contaminants in the airstream, efficiently removing them from your air.
Alkaline, acidic, or oxidizing scrubbing agents are often used in the recirculated scrubbing liquid in order to achieve the desired outlet emissions. For vertical, countercurrent scrubber operations, contaminated gas will flow upward through the bed of the vessel while the scrubbing liquid irrigates downward through the bed by means of gravity.
At the top of the scrubber, a liquid distribution header evenly distributes the scrubbing solution to get a uniform distribution of liquid across the top of the packing.
As the air moves up through the packing, the extended contact time between the air and the liquid allows the scrubber to absorb or react with the contaminants. Before the scrubbed air leaves the vessel, it passes through a mesh or chevron mist eliminator in order to remove any entrained droplets of liquid, ensuring that the outlet airflow is of the highest quality.
Packed bed were created to improve contact between two phases in a chemical or similar process. They can be used in a chemical reactor, a distillation process, or a scrubber , also beds have been used to store heat in chemical plants. The packed bed scrubbers is designed to remove gaseous or vaporous pollutants from an air stream. The process is accomplished by contacting the contaminated air stream with a scrubbing liquor that absorbs or chemically reacts with the pollutants.
The cleaned air is then discharged to the atmosphere and the contaminated scrubbing liquor is either disposed of in the approved can be recovered and reused in the original on other processes. In the vertical counter-current design, gas flows upward while scrubbing liquid flows down through banks of sprays. Our experienced engineers will design vessel, packing and system components to suit your specific application.
