  • Hydrogen sulfide scavenger for use in hydrocarbons
    Patent number: 9394396
    Abstract: An effective hydrogen sulfide scavenger that produces little corrosion may be prepared by reacting glyoxal with a compound having at least two primary or secondary amine groups. The subject hydrogen sulfide scavengers may be used with both the production of crude oil and natural gas, and the refining of same.
    Type: Grant
    Filed: June 19, 2012
    Date of Patent: July 19, 2016
    Assignee: Baker Hughes Incorporated
    Inventors: Joseph L. Stark, Robert A. Steele, Ksenija Babić-Samard{hacek over (z)}ija, John A. Schield, Weldon J. Cappel, Matthew T. Barnes
  • Non-nitrogen sulfide sweeteners
    Patent number: 8357306
    Abstract: A process for removing a sulfur species from a stream selected from the group consisting of a hydrocarbon stream, an aqueous stream, and mixtures thereof is disclosed herein, which may include introducing a treating mixture into the stream. The treating mixture may include a compound of the general formula selected from the group consisting of: or combinations of compound (I) or compound (II). R1 may be a C1-C30 hydrocarbyl group that is saturated, unsaturated, cyclic or branched, or may contain a heteroatom. ‘A’ may be an oxygen atom or a methylene group. R2 may be a C1-C30 hydrocarbyl group that may be saturated, unsaturated, cyclic or branched, or may contain a heteroatom(s) other than C and H. The treating mixture may reduce the reactive sulfur species in the stream. The sulfur species reduced from the stream may be hydrogen sulfide, mercaptans, polysulfides, or combinations thereof.
