Jet Venturi Scrubbers
The Jet Venturi Scrubber utilizes a liquid motivated ejector design to entrain contaminated gases, generally without the need for a blower. The relatively high liquid-to-gas ratio, liquid atomization, and open internal design provide effective scrubbing of heavily contaminated gases with minimal maintenance and virtually unlimited turndown capabilities. Its ability to handle wide ranging conditions while removing both toxic gases and particulate matter makes the Jet Venturi one of the most flexible designs available. It is often used as a first stage in a multi-stage pollution control system.
 High Energy Venturi Scrubbers
The High Energy Venturi Scrubber is ideally suited to the capture of small particles between 0.5 and 3 microns. It's effectiveness in the submicron range is critically dependent on gas-side pressure drop. This design requires little or no maintenance.
For applications where variation in flow require throat velocity compensation to maintain specified scrubbing efficiencies, The Clean Air Group, Croll-Reynolds LLC offers automatic and manually variable throat designs. The automatic throat is used where flow conditions vary widely and frequent adjustments are required. When occasional variations occur, a manually-controlled throat is generally sufficient.
Packed Tower Wet Scrubbers
Packed tower wet scrubbers are ideal for ultra high removal efficiencies of acid or basic gases and water soluble VOC's . From ppm to high vol% concentrations of the contaminant, the packed tower can be designed to achieve desired effluent stream limits. Removal efficiencies of 99.99+% can be achieved by proper selection of packing type, size, packing bed height and liquid to gas recycle rate. The packed tower is compact and simple in operation, requiring generally only a recycle pump and ID fan. Occasionally an in line heat exchanger is required to dissipate large exothermic heats of reaction resulting from the chemical reactions of the contaminant with the scrubber liquor. Exhaust gases containing solid particulate must be pretreated to remove the solids to avoid plugging the packing. The packed tower comes in a variety of diameters, heights and materials of construction making it a most versatile unit for most all scrubbing applications.
EtO/PO Scrubbers
Ethylene Oxide gas (EtO) is used to reduce or render inactive microbial populations in sterilization processes. EtO sterilizes materials and products that would be damaged by conventional sterilization techniques which employ heat, moisture, or radiation. Propylene Oxide (PO) and Ethylene Oxide are also used as precursors in the production of a number of critical chemicals.
The Clean Air Group, Croll-Reynolds LLC proprietary EtO/PO scrubbing systems utilize absorption and hydrolysis of these oxides to glycols to effectively treat EtO and PO contaminated gases. Efficiencies greater than 99.9% are guaranteed. Fully automated systems are available.
NOx Scrubbers
Conventional scrubbers are limited to low NOx removal efficiencies due to the nature of the aqueous absorption chemistry involved. The Clean Air Group, Croll-Reynolds LLC patented "Surface Active" media effectively overcomes those limitations -- without the need for exotic or expensive chemicals or a costly and complex operational scheme.
This technology is particularly well suited for applications where the infamous "orange" plume is produced by high levels of NOx.
The Clean Air Group, Croll-Reynolds LLC can supply the scrubber alone or as a complete systems with auxiliary instrumentation and controls.
Mercury Scrubbers
Specialized scrubbing systems are available for mercury removal and separation for complete recovery. This patented process utilizes new developments in high voltage technology to achieve complete recovery of mercury.
