Abstract
The deposition of elemental sulfur in a conduit through which a sulfur containing gas is flowing is reduced by providing, as a novel sulfur dispersant, an ether alcohol component produced from primary alcohol and epichlorohydrin mixed with an aliphatic amine component, the dispersant being employed in the presence of liquid water. When the conduit is normally vulnerable to the corrosion caused by contact with the sulfur-containing gas, the sulfur dispersant is optionally employed in conjunction with a corrosion inhibitor.
