ABSTRACT:
Viscous liquids, such as liquid sulfur and bitumen asphalt are contacted with gases to strip absorbed gases from the viscous liquid and/or transfer gaseous components into the viscous liquid using a shrouded impeller combination immersed in the viscous liquid. The invention has particular application to the stripping of hydrogen sulfide and hydrogen polysulfides from liquid sulfur using an oxidizing gas.
