摘要： A method of removing hydrogen sulfide from water is provided, comprising providing water containing a first amount of hydrogen sulfide and having a first pH; adding a stripper gas to the water to form a mixture; agitating the mixture; and separating a gaseous portion from the mixture to form a water product, the water product containing a second amount of hydrogen sulfide that is less than the first amount of hydrogen sulfide.

摘要： A process and process line for treating water containing hydrogen sulfide for use as a hydraulic fracturing fluid is provided, to practice the following steps: separating a gaseous portion containing hydrogen sulfide from the water to form a first degassed water product; introducing the first degassed water product into a mechanical gas stripping unit and treating the first degassed water product with a stripper gas; recovering from the mechanical gas stripping unit at least one overhead vapor stream containing hydrogen sulfide and a stripped water stream as a bottom stream; degassing the stripped water stream in a degassing tank to produce a second degassed water product; and treating the second degassed water product with a hydrogen sulfide scavenger to produce a sweet water product having substantially reduced hydrogen sulfide.
摘要翻译： 提供了一种用于处理含硫化氢的水作为水力压裂液的方法和工艺流程，用于实施以下步骤：从水中分离含有硫化氢的气态部分以形成第一脱气水产物; 将第一脱气水产物引入机械气体提取单元并用汽提器气体处理第一脱气水产物; 从机械气体提取单元回收至少一个包含硫化氢的塔顶蒸气流和作为底部流的汽提水流; 在脱气罐中将汽提的水流脱气以产生第二脱气水产物; 并用硫化氢清除剂处理第二脱气水产物以产生具有显着减少的硫化氢的甜水产品。
