While recovering sulfur in an SRU depends on condensation of sulfur, its unintended condensation and accumulation can present problems. The paper analyses areas where this may be expected and presents case histories of sulfur build-up in SRU equipment, such as waste heat boilers, reheaters, sulfur condensers and coalescers.
The risks involved in accumulation of sulfur are discussed, both for the operation of Claus plants and for the operation of SUPERCLAUS® plants, for which liquid sulfur may pose extra risks. Ways are discussed to prevent accumulation and minimize the risks
