Scrubber Basics - Engineering ToolBox

Venturi scrubbers - air or gas velocity is increased through a venturi shape - increased turbulence atomize the water droplets ; Fiber-bed scrubbers - air passes through wet-laden fiber mats where mists are collected. Not suited if solid particles are present in the air since the fiber mats may plug; Mechanical scrubbers - a mechanical driven rotor produces the fine water droplets in the air ...

Mechanical filter - Wikipedia

A mechanical filter is a signal processing filter usually used in place of an electronic filter at radio frequencies. Its purpose is the same as that of a normal electronic filter: to pass a range of signal frequencies, but to block others. The filter acts on mechanical vibrations which are the analogue of the electrical signal. At the input and output of the filter, transducers convert the ...

Gas scrubbing - general | EMIS

The liquid-gas ratio (L/G) in a scrubber is the relationship between the scrubbing liquid flow rate and the gas stream flow rate. For dimensioning purposes, and to evaluate the workings of a scrubber, it is important to know how much liquid is required per m³ to realise the required residual emission. The L/G ratio is not only determined by the required residual emission, but is also partly ...

How CO2 Scrubbing Works | HowStuffWorks

­­ Even taking into account its own energy usage and emissions, though, CO 2 scrubbing still removes a net amount of 80 to 90 percent of the carbon dioxide from flue gas [source: GreenFacts]. That's a good thing, since some scientists estimate our emissions of CO 2 may need to be reduced by 60 to 80 percent to avoid catastrophic climate changes [source: Marion ].
