Abstract
The disclosure provides a system for removal of hydrogen sulfide from oil and gas by the reaction of H2S with hydrocarbons in the presence of a UV light source to produce easy to remove organosulfur compounds.
Claims14
A method for removing H2S from reservoir fluids, said system comprising:
- a) separating a produced reservoir fluid into a produced water stream, a crude oil stream and a sour gas stream, said sour gas stream comprising >20 ppm H2S and one or more alkane(s) or alkene(s) or both;
- b) exposing said sour gas stream to sufficient ultraviolet (UV) to convert said H2S and said one or more alkane(s) or alkene(s) or both to an organosulfur compound and a sweet gas with zero or trace H2S;
- c) optionally removing said organosulfur compound and said zero or trace H2S from said sweet gas;
- and
- d) storing, distributing or liquifying said sweet gas.
2 more elements
A system for removing H2S from reservoir fluids, said system comprising:
- a) a separator for separating a produced reservoir fluid into a produced water stream, a crude oil stream and a sour gas stream, said sour gas stream comprising >20 ppm H2S and one or more alkane(s) or alkene(s);
- b) a UV reactor unit comprising a UV transparent piping fluidly connected to said sour-gas stream and having one or more UV lights adjacent said piping and configured to emit sufficient UV light to an interior of said piping to convert said sour gas to an organosulfur compound and a clean gas stream;
- c) said organosulfur compound and clean gas stream fluidly connected to a storage or distribution system.
