The following is a series of mini‐case histories representative of our experience:

The emergency plan at a specialty chemical plant located in the Midwest relies on aThe Clean Air Group, LLC Packed Tower. In the unlikely event of a catastrophic release of ammonia from the plant’s refrigeration system due to an unexpected rupture, our once‐through tower would remove ammonia at an efficiency of 99% for a single valve release, and well over 90% over the entire range of operation.


Wet-ScrubbersA local chemical provider has never had a serious spill of phosphorus oxychloride (POC13), but its dedicated unloading facility is prepared for the worst case scenario. The stand-by emergency scrubbing protocol relies on a two-stageThe Clean Air Group, LLC system consisting of a 1st stage jet venturifume scrubber followed by a 2nd stage counter current packed tower to handle both POC13 and HCL emissions.

Speaking of HCL, we have a long history in providing HCL emission control systems to meet regulatory requirements while recovering byproduct for sale. This schematic below shows venturis and a heat exchanger for HCL recovery, as well as packed towers for tail gas scrubbing. Overall emissions from this system are typically 2 ppm or less.


In a tightened economy, it’s more important than ever to specify a pollution control system that serves your precise needs with the removal rate your local regulations demand. Overdesign increases purchase price and operating costs… under design results in an inadequate system, not capable of doing the job you require and possibly incurring fines for non‐performance.

The Clean Air Group, LLC ’s application engineers have years of experience in designing and optimizing units and systems. We do not deal in “standard” off‐the‐shelf models that “come close” to meeting the customer’s needs.
