Patent number: 10093868Abstract: Treatment of hydrocarbon streams, e.g. gasoline, with basic ionic liquids (ILs), results in reduction of the sulfur compounds such as H2S thiophenes, disulfides, thioethers, and/or mercaptans that are present to remove these compounds. The IL is a quaternary ammonium compound having the formula R4N+ X? or X? R3N+R?N+R3 X?, where R is independently an alkyl group, an alkylbenzyl group, a hydroxyalkyl group, or a hydroxyalkylbenzyl group, and R is straight or branched and has 1-22 carbon atoms, R? is a straight or branched alkylene or oxyalkylene having 1 to 10 carbon atoms, and where X? can be hydroxide, carbonate, alkylcarbonate, bicarbonate or alkoxide, where the alkyl group of the alkylcarbonate or alkoxide, if present, is straight or branched and has 1 to 8 carbon atoms. The ILs can be used in applications where liquid or gaseous hydrocarbon fluids are treated by direct injection or by extraction.Type: GrantFiled: November 15, 2017Date of Patent: October 9, 2018Assignee: Baker Hughes, a GE company, LLCInventors: Jerry J. Weers, Henry Nguyen, Weldon J. Cappel, Kimchi T. Phan

Patent number: 8523994Abstract: Hydrogen sulfide evolution from asphalt may be reduced or eliminated using an additive to act as a scavenger. Zinc oxide, when present in the form of nano-particles is an effective component is preventing or mitigating the evolution of hydrogen sulfide from asphalt. Zinc sulfonate may also be used. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).Type: GrantFiled: December 9, 2008Date of Patent: September 3, 2013Assignee: Baker Hughes IncorporatedInventors: Jennifer D. Draper, Mark R. Williams, Weldon J. Cappel, Jerry J. Weers

Patent number: 6887447Abstract: The present invention provides a method for inhibiting the evolution of H2S from sulfhydryl compounds in molten sulfur by using scavenging agents such as anhydrides and polymers thereof, conjugated ketones, carbonates, epoxides, monoesters and diesters of unsaturated dicarboxylic acids and polymers of these esters, and the like and mixtures thereof. In one embodiment, it is preferred that the scavenging agent is in liquid form at contact temperature with the molten sulfur. In another embodiment, the scavenging agent may be atomized into the vapor space over the molten sulfur to contact the sulfur with the agent.Type: GrantFiled: October 17, 2003Date of Patent: May 3, 2005Assignee: Baker Hughes IncorporatedInventors: John A. Schield, Weldon J. Cappel, Jerry J. Weers, Glenn L. Roof
