(335c) Liquid Droplet Measurements Using a Laser Scattering Technique

Wet gas requires a strict purification degree in order to obtain dry gas and be in the specification to be sold. The regular purification equipment is a scrubber, where droplets are removed form the gas stream. To carry on this process, several steps are taking place inside the scrubber; one of them is a mesh pad that will remove big droplets by coalescence with mesh's wires.

The knowledge of the droplet size distribution before and after the mesh pad is of high relevance due to the fact that this information is a way to evaluate the performance and efficiency of the separation equipment.

In this work it was used a light scattering technique of a laser in order to measure droplet size distribution of air-liquid system. Distilled water, regular sink water, glycerol, acetone and ethanol have been tested. Their results have been compared and a tendency correlation has been obtained.

It was found that the technique was accurate and its accuracy was checked with an optical/visual technique of high speed cameras' measurements.
