Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to an integrated desulfurization device for sulfur-containing gas field water. Background Art

[0002] Sulphur-containing gas field water is produced water brought out of the formation during the mining process; Sulphur-containing gas field water is highly corrosive and contains highly toxic sulfides. Once problems occur in the production links such as drilling and completion, underground gathering and transportation, and natural gas purification, serious environmental and safety accidents will occur. Therefore, it is necessary to desulfurize the sour gas field water;

[0003] Most of the existing desulfurization methods use air oxidation, which mainly uses oxygen in the air to oxidize and remove sulfides in sewage. At the same time, when the air escapes, it carries out some sulfides in the sewage in the form of hydrogen sulfide. This technology generally does not completely treat the sulfides in sewage. The low treatment efficiency leads to large equipment size and high cost. The treatment process pollutes the environment or corrosive to pipelines / equipment, and safety cannot be guaranteed. For this reason, we propose an integrated desulfurization device for sulfur-containing gas field water. Utility Model Content
