BIONOMIC RotaBed™ Fluidized Bed Scrubber System for Ultra High Efficiency Gas Absorption and Particulate Removal Overview The Bionomic RotaBed12 Gas Scrubber represents a major technological breakthrough designed to provide ultra high efficiency gas absorption or particulate removal. The key to the RotaBed’s superior performance is a unique, swirl-induced Coriolis effect created in the scrubber’s turbulent, high mass transfer bed.This effect provides superior stability and turndown capability over less advanced designs. Combined with a “packless”, highly plug-resistant grid cross section that is 99% open in the fluidized contact/scrubbing zone, RotaBed delivers exceptionally high gas throughput capacity (4-6 times greater than packed towers or tray scrubbers) that results in maximum scrubbing efficiency at lower costs. RotaBed Scrubbers are available in all materials of construction with standard models from 130-122,900 acfm and larger sizes on a custom basis. A cost-effective skid-mounted ScrubPac™ version comes prepackaged with all auxiliary piping, pumps, instrumentation, and other necessary components for slide-it-in, hook-it-up operation. Pilot rental units are also available for on- I site testing and are backed by complete process and engineering support.

Operating Principle During operation, contaminated gas and particulate matter enter the scrubber’s gas inlet and flow upward while scrubbing liquid is introduced via the liquid scrubbing distributor. A stationary Coriolis swirl inducer, with gas turning vanes and liquid drain s l e eve, imparts an angular component to the upflowing gas and a vortex swirl to the draining liquid to rotate the bed.The scrubber’s open, “packless” plug-resistant grid creates and defines the fluidized scrubbing zone. Fully open, straight pipe liquid inlets devoid of spray nozzles that can plug or blind are used...
