Abstract (en)
[origin: US2012012507A1] The invention provides a method of removing hydrogen sulfide from hydrocarbon fluids. The method involves using an alpha-amino ether as a hydrogen sulfide scavenger. This allows for the introduction of an oil soluble scavenger in lieu of water-soluble scavengers.
