APPARATUS FOR REDUCING THE HYDROGEN SULPHIDE AND HYDROGEN POLYSULPHIDE CONTENT OF LIQUID SULPHUR

摘要

Apparatus for reducing the hydrogen sulphide and hydrogen polysulphide content of liquid sulphur wherein the liquid sulphur is aged and agitated by passage through a storage tank and scrubber where the surface area of the liquid sulphur is increased and the dissolved hydrogen sulphide is allowed to escape. The apparatus also enables the more thermally stable polysulphides to break down into hydrogen sulphide gas and liquid sulphur. By repeated recycling the hydrogen sulphide and polysulphide content of the liquid sulphur can be reduced to negligible amounts.
