CR Clean Air - High Energy Venturi Scrubber
From Products
The High Energy Venturi Scrubber is ideally suited to the capture of small particles less than 3 microns in size. It is effective as well in the submicron range and requires little or no maintenance. For applications where variations in gas flow require throat gas velocity compensation to maintain specified scrubbing efficiencies, the Clean Air Group, 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 available.
CR Clean Air
Meeting the Challenge
The California site of the TRW Strategic Defense Initiative (SDI) laser project is one of the world's largest vacuum and air pollution control installations. Ejectors manufactured by Croll Reynolds simulate the atmosphere of space for the testing of a hydrogen/fluorine laser. Gases produced during laser generation are removed by a CR Clean Air custom-designed Packed Tower Scrubber.
For over 50 years now, CR Clean Air has provided solutions to those faced with the challenge of efficient resource utilization and the responsibility for meeting stringent emission standards.
Current and proposed regulations call for swift compliance, while the recovery and reuse of valuable process vapor has become standard operating procedure throughout the world.
Regardless of the air pollutant or industrial source. CR Clean Air has the engineering know-how and application experience to design and manufacture a system to meet the most demanding performance requirements.

Specialized Applications
ETO/PO Scrubbers
Ethylene Oxide gas (EtO) is used to reduce or tender inactive microbial populations in sterilization processes. Propylene Oxide (PO) and Ethylene Oxide are also utilized as precursors in the production of a number of critical chemicals.
CR Clean Air's 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 99.99% can be 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. CR Clean Air's patented 'Surface Active' media effetely overcomes those limitations -without the need tor 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 NO2.
Air Pollution Control Systems
Wet Scrubbers
CR Clean Air's Jet-Venturi Scrubber is one of (tie most economical answers to the growing problem of air pollution. It is an efficient means for minimizing smoke and undesirable odors, cleaning and purifying air and other gases as well as reclaiming valuable product which may be exhausted to the atmosphere. It can also be used as a concentrator by having the motivating fluid adsorb the fume for recirculation until a desired concentration is reached. And the Fume Scrubber can do all this with a minimum of maintenance since there are no moving parts and because it operates at low velocities.
Packed Tower Scrubber
CR Clean Air's Packed Tower Scrubber utilizes a vertical countercurrent design for highly efficient absorption of a variety of toxic gases. In addition to its extensive use in air pollution control, the Packed Tower can serve as a gas/liquid contactor in a number of process applications. Efficiencies of 99.99% and greater are not unusual for many scrubbing applications. During operation, gas flows upward through a packed bed while scrubbing liquid flows down (by gravity) over the packing material. The counter-flow design principle offers optimal mass transfer. CR Clean Air supplies cross flow and co-current flow Packed Tower designs as well.
High Energy Venturi Scrubber
The High Energy Venturi Scrubber is ideally suited to the capture of small particles less than 3 microns in size. It is effective as well in the submicron range and requires little or no maintenance.
For applications where variations in gas flow require throat gas velocity compensation to maintain specified scrubbing efficiencies, CR Clean Air 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 available.
Jet Venturi Scrubber
The Jet Venturi Scrubber utilizes a liquid motivated ejector design lo 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 makes the Jet Venturi one of the most flexible designs available. It is often used as a first stage in a multi-stage air pollution control system.
Jet Venturi Scrubber
Motivating fluid exits the nozzle in a hollow cone spray pattern, creating a draft. Contact between the scrubbing liquid and the gas results in high gas mass transfer and/or particulate capture. This mixture discharges into a CR Clean Air designed separator.
Packed Tower Scrubber
Utilizing the most modern packing designs to provide contact between gas and liquid streams, the Packed Tower Scrubber achieves the extremely low toxic gas discharge limits required to meet emission standards.
High Energy Venturi Scrubber
Energy from a high-velocity, dust laden gas stream is used to atomize a liquid stream. Cyclonic gas flow in the separator drives the dust laden liquid to the outside wall. The liquid is collected and returned to the sump.
