TREATMENT OF WATER FOR USE IN HYDRAULIC FRACTURE STIMULATION |
摘要 |
<p>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.</p> |
