Occasionally in high H2S pipelines, elemental sulphur physically precipitates as micro particles with an average size of 30 microns or less. These particles precipitate in the pipeline, thus causing under deposit corrosion.
Solvents to remove this are generally very flammable, toxic and expensive. This elemental sulphur can instead be most efficiently removed from the gas/liquid stream by using Burza's vortex cyclone skid to separate and collect these particles.
