This is to be expected as there are so many variables to consider when going through various options, including venturi, packed-bed, or eductor venturi wet scrubbers. Particles down to and including submicron sizes can be captured. Considering 20% safety factor, HETP = 0.8450653m For separations, requiring 15 to 25 theoritical stages, a 15% design safety factor can be applied. Venturi Meter Design Equations Calculator Fluid Mechanics Hydraulics Formulas. The small amounts of energy converted into heat within viscous boundary layers tend to lower the actual velocity of real fluids somewhat. The scrubber is a Venturi scrubber designed to recirculate water to remove fumes from a gas stream. The key feature of the Kiekens Venturi Desuperheater is that it obtains a stable conditioned desuperheated steam flow temperature handling high amount of cooling water injection in the shortest possible time. endobj Applicable Pollutants: Venturi scrubbers are primarily used to control particulate matter (PM), including PM less than or equal to 10 The open design eliminates opportunities for the solids buildup and minimizes maintenance.

Excel formulas use the ideal gas law to calculate the density of a gas for known gas molecular weight, temperature and pressure. Sourcing a wet scrubber often means a back-and-forth discussion between you and the supplier. Solving for the upstream velocity V a and multiplying by the cross-sectional area A a gives the volumetric flowrate Q, : Ideal, inviscid fluids would obey the above equation. Hence, of the conventional particulate scrubber types, a gas- atomized scrubber, such as a venturi or rod scrubber, is recommended. η = 1 – e^ (-k*R*sqrt (ψ)) ---- (1) where: η = collection efficiency of the venture scrubber, fraction.
