ABSTRACT:
A vessel is mounted external to a liquid sulfur storage pit for degassing liquid sulfur at atmospheric pressure. Liquid sulfur is re-circulated from the pit to a static mixing device extending from a head space to the liquid sulfur which provides intimate contact of the liquid sulfur as it flows downwardly and sweep air flowing through the head space above the pit. Further, the static mixing device prevents free fall of liquid sulfur and the hazards of static electricity associated therewith. Use of a heat traced gas outlet induces flow of sweep gas from the system, obviating the need for a steam eductor or blower.
