Drop Size Measurements in a Laboratory Scale Venturi Scrubber

Performance of Venturi Scrubber

In this article we have made an attempt to survey some results on performance of jet ejector. The literature is also reviewed to pursue further work in this area. Key wordsHEVS, EVS, jet ejector, performance of venture scrubber, characteristics of jet ejector, efficiency

Droplet Dispersion Angle Measurements on a Pease-antony Venturi Scrubber

A Pease-Anthony Venturi scrubber is a gas cleaning device that uses liquid, injected in the equipment as jets, to remove contaminants from the gas. The liquid jet is atomized into droplets, which are dispersed throughout the equipment due to the turbulence. The performance of the scrubber is affected by the spatial distribution of the droplets. Although CFD models have been used to predict the ...

Mean Drop Size and Drop Size Distribution in a Hanson Mixer-Settler Extraction Column

Particle collection efficiency in a venturi scrubber: comparison of experiments with theory.

Particle collection efficiencies in 23 size intervals covering a diameter range of 0.32-2.8 pm were measured for venturi scrubbers with throat diameters of 3.2,5.4, and 7.6 cm. Each scrubber was operated with four types of liquid injection, throat gas velocities from 21 to 160 m/s, and liquid-to-gas volume ratios from 0.000 19 to 0.0043. Results were compared to three widely used theoretical mo...

Small-Scale Drop-Size Variability: Empirical Models for Drop-Size-Dependent Clustering in Clouds

By analyzing aircraft measurements of individual drop sizes in clouds, it has been shown in a companion paper that the probability of finding a drop of radius r at a linear scale l decreases as l, where 0 D(r) 1. This paper shows striking examples of the spatial distribution of large cloud drops using models that simulate the observed power laws. In contrast to currently used models that assume...
