Research and application of dissolved sulfur agent for high-sulfur gas field

The elemental sulfur deposition of high-sulfur gas field affected production directly and caused serious corrosion, which did great harm to the safe and efficient production of gas field. This paper researched the new dissolved sulfur agent system, which took DMDS as main agent and MAT as catalyst. At 50℃, 100 g agent could dissolve 50 g sulfur power in 1.25 minutes. The saturated dissolved sulfur content of agent is 241 g per 100 g, and it has a good compatibility with corrosion inhibitor. The dissolved sulfur agent field tests demonstrated that the broken down process efficient of element sulfur deposition is more than 90%.
