Abstract: Disclosed are systems and methods for producing oil and gas while removing hydrogen sulfide from fluids produced from oil and gas reservoirs and injecting a sour gas stream containing the hydrogen sulfide into an underground formation. Hydrogen sulfide-selective membranes are used to debottleneck known systems and methods by removing hydrogen sulfide from bottlenecked plant process steps including sour gas compression, hydrogen sulfide removal and sour gas injection. Pressure ratio across the membranes can also be manipulated to provide further debottlenecking. Gas-gas eductors are also disclosed for use in leveraging relatively high-pressure streams to boost the pressure of low pressure streams. Oil production is thus increased.

Abstract: A method is provided for recovering mercury from a crude oil into an alkaline ammonium sulfide contacting solution. Soluble mercury complexes in the contacting solution are converted to particulate mercury. The particulate mercury can be recovered by filtering, and the ammonium sulfide in the contacting solution recycled to the aqueous contacting solution.

Abstract: A crude oil which contains at least 0.1 wt % unstable sulfur compounds is treated in a reaction zone at low temperature to convert at least 50 wt % of the unstable sulfur compounds contained therein. The reaction and removal of sulfur from the crude may be facilitated by contacting the crude oil with a catalytic material in the presence of a stripping fluid.

Abstract: Disclosed are methods and systems for reducing elemental sulfur production in a gas production plant that includes receiving produced fluids high in hydrogen sulfide, removing hydrogen sulfide and converting hydrogen sulfide to elemental sulfur in a Claus unit. An acid gas stream is diverted from a feed line to the Claus unit in the gas processing plant and directed to a multistage acid gas compressor. An elemental sulfur production rate is reduced without reducing a production rate of the produced fluids. The compressed acid gas stream can be injected into a subterranean formation. In some embodiments, the gas production plant is integrated with an oil processing and gas injection plant.

Abstract: Disclosed are systems and methods for producing oil and gas while removing hydrogen sulfide from fluids produced from oil and gas reservoirs. Hydrogen sulfide-selective membranes are used to remove hydrogen sulfide from bottlenecked plant process steps including hydrogen sulfide removal. In some embodiments of the present disclosure, plant processing efficiency is improved for processing of high temperature associated gas streams by using membranes while integrating heat from other existing process streams. In other embodiments of the present disclosure, plant processing efficiency is improved for processing of high temperature associated gas streams by using high temperature tolerant polymer membranes. Oil and/or gas production is increased.

Abstract: Disclosed are systems and methods for increasing oil production in an integrated oil and gas production plant including hydrogen sulfide removal and sour-gas injection into an underground formation. Hydrogen sulfide-selective membranes are used to debottleneck known systems and methods by removing hydrogen sulfide from bottlenecked plant process steps including sour gas compression, hydrogen sulfide removal and sour gas injection. A method of retrofitting an integrated plant includes adding a hydrogen sulfide-selective membrane upstream of an amine unit to remove hydrogen sulfide from an associated gas stream and form a permeate stream enriched in hydrogen sulfide and a retentate stream depleted in hydrogen sulfide and enriched in hydrocarbon gases. Less hydrogen sulfide is sent to the amine unit and oil production is higher than in the integrated plant without the hydrogen sulfide-selective membrane.

Abstract: A process for reducing total acid number (TAN), comprising: contacting, without hydrogen addition, a liquid hydrocarbon having a high initial TAN with a ternary catalyst comprising titanium-oxide, a metal promoter, and a porous support; wherein the contacting occurs over a short time or at a defined LHSV, and at a low contacting temperature, and wherein the contacting reduces the initial TAN by at least 20%. Also, a new ternary catalyst that reduces the TAN, wherein the ternary catalyst has a molar ratio of titanium to metal from the metal promoter that is greater than 3:1.
