BECO WET SCRUBBERS

As a chemical engineering group, Beco Engineering is thoroughly conversant with countercurrent packed and plate scrubber design and technology. However, there are many challenging emission control problems that cannot be met by conventional scrubbing equipment. Beco has repeatedly met these challenges by new and innovative scrubber designs that utilize novel applications of fundamental fluid dynamics. These include:

The "Smoke-Ring" Vortex Scrubber

This scrubber design generates a series of stable standing vortices, or inverted "Smoke-Rings". Atomized spray droplets are injected into the gas flow and are trapped in the closed-ring rotational flows, creating a series of high-density droplet concentration zones. The "Smoke-Ring" scrubber offers exceptional mass transfer capabilities, but its principal application has been in ultra-low energy particulate scrubbing. Over 4,000,000 ACFM of "Smoke-Ring" scrubber capacity is now in service on fume scrubbing in the fertilizer industry alone.

The Multi-MicroVenturi (MMV) Scrubber

The MMV combines the principles of repeated venturi flow with multiple target impingements. Utilizing a 4-row bank of cylindrical elements separated by connecting partitions, the MMV generates successive micro-venturi flows and impingement stages in gas traversing the array. Injecting water spray upstream of the MMV array yields a unique and effective mass transfer unit or particulate scrubber. The MMV has seen broad application for dust removal in the explosives industry and acid gas/particulate removal in the aluminum, steel and chemical industries.

The Venturi Recycle Tray (VRT) Scrubber

The VRT is a radically different gas-liquid contact tray. The most distinctive property of the VRT is that, at 2" W.C. pressure drop, it automatically generates a directed high liquid recycle flow around the tray without the use of a pump. Because of the gas venturi lift action, tray liquid recycle depends only on the gas flow rate, and is entirely independent of the liquid throughput. Sustained tray liquid recycle ratios as high as 50 times tray liquid throughputs can easily be achieved. The virtually unlimited liquid/gas ratios available from a VRT provide extraordinary versatility and efficiency in mass transfer applications. VRT's are in service on many waste incinerator flue gas scrubbers, as well as in acid gas and odor removal applications.

Brush-Pack & e-PackŪ Scrubbers

The unique properties of the e-PackŪ and "Brush-Pack" mist eliminators have led to their use in dedicated scrubbers. While e-PackŪ has been extensively used for oil mist elimination, its ability to tolerate solids has been used in wet scrubbers for dust/mist removal. Similarly, "Brush-Pack" has been used as in packed bed scrubbers for fine particulates, including black powder, TNT, detergent powder, lime and foundry dusts and pitch.
