Abstract
Certain exemplary embodiments can provide a system, machine, device, manufacture, circuit, composition of matter, and/or user interface adapted for and/or resulting from, and/or a method and/or machine-readable medium comprising machine-implementable instructions for, activities that can comprise and/or relate to, reacting reactants comprising a ferric/ferrous chelate and a sour gas stream.
Claims24
A method comprising:
- in a substantially anaerobic treatment zone of a manmade container, reacting reactants comprising a ferric/ferrous chelate and an input gas stream, the input gas stream comprising natural gas and hydrogen sulfide, wherein:
- reaction products of the reacting comprise:
- a spent ferric/ferrous chelate that is substantially saturated with sulfide;
- and
- an output gas stream having a concentration of hydrogen sulfide of no greater than 3.5 ppm;
- a content of the treatment zone is actively maintained at a pH of between approximately 5.55 and approximately 9.25 and an oxidation-reduction potential of between approximately −31 mV and approximately −425 mV.
