Abstract: A gradual fiber cladding light stripper and its manufacturing method is disclosed to include an optical fiber that has a core, a cladding outside the core and an outer coating outside the cladding, the outer coating being removed by a preset cutting fixture to form a pre-stripping section, and a recoating section coated on the surface of the pre-stripping section at one time with a covering glue, the covering glue being irradiated and cured through a preset light curing device to form the recoating section with a gradual light stripping rate. The recoating section has a laser light input terminal with a relatively lower light stripping rate, and a laser light output terminal with a relatively higher light stripping rate.

Abstract: The disclosure relates to systems and methods to photolytically cleave hydrogen sulfide (H2S) present in a gas mixture produced by a hydrocarbon producing well and/or a gas treatment unit, thereby converting the hydrogen sulfide to hydrogen gas (H2) and a sulfur species (e.g., elemental sulfur, polysulfides, and/or organosulfur compounds). This reduces the amount of hydrogen sulfide present in the gas mixture. The systems and methods can be implemented in a component of a hydrocarbon producing well (e.g., a wellhead, a flow line, a production casing, a production tubing), a component used to transport the gas mixture produced by the well (e.g., a transportation pipeline, an inlet to a gas-oil separation plant), and/or a gas treatment unit (e.g., a tail gas treatment unit). The gas mixture is disposed in an annular space of the component(s), and an ultraviolet (UV) light source delivers UV light to the gas mixture to photolytically cleave the hydrogen sulfide.
