Description: Use of diaryl disulfide (DADS) sulfur solvent was successful in removing sulfur from tubulars and flow lines at Exxon Co. USA's LaBarge field in Wyoming. Additionally, the company's experience indicates that sulfur deposition can be a concern for gases with less than 5% hydrogen sulfide and that phase behavior and well bore hydraulic models can be used to predict where, and how much, sulfur can be expected to be deposited. Deposition of elemental sulfur in tubulars and flow lines can lead to decreased production, increased corrosion, and higher filtration-water disposal costs. These problems have been seen at LaBarge field even though its 5% hydrogen sulfide concentration is below a level at which sulfur deposition is normally a concern. In its LaBarge application, Exxon found DADS to be preferable for sulfur-deposition problems because it was cheaper, less volatile, and easier to regenerate with no disposal needed, when compared with the more commonly used solvent, dimethyl disulfide.
