Abstract
The invention relates to a process for removing sulfur particles from an aqueous catalyst solution used to remove hydrogen sulfide from a gas stream (), comprising the steps of directing a flow of a suspension () comprising reduced catalyst solution and sulfur particles to an oxidizer zone (), where the catalyst solution is regenerated by contacting said suspension with a gas () containing oxygen; and removing sulfur from said suspension at least by gravity sedimentation at a bottom () of said oxidizer zone (). According to the invention a flow deflecting means () is disposed at least at an outlet () for the oxidized catalyst solution leaving said oxidizer zone () such as to prevent any turbulent state caused at least by a stream of oxidized catalyst solution leaving said oxidizer zone ().
