Bionomic Industries has the Series 6000 Tray Scrubber. Available in sizes to handle gas volumes from 500 to 150,000 cfm, the unit uses special high-performance tray designs in single or multiple stages, the company says.
This achieves maximum gas absorption using once through water at extremely low rates to absorb and concentrate product in one easy step, without the need for recirculation pumps, Bionomic adds.
The once through water flow pattern also enables recovery of higher vapour pressure concentrated solutions for reuse in the process.
For applications when fine mists are formed during absorption, a final coalescing filter is used to reduce overall emissions to extremely low, nearly non-detectable levels to easily meet environmental standards, the company says.
The tray scrubber is suitable for recovering and re-concentrating acids such as hydrochloric from metal pickling operations, acetic acid, ammonia and alcohols from supply and process operations including a host of other emission source compounds.
