  • Publication number: 20150314235
    Abstract: A cyclic process for separating CO2 from a gas stream by contacting the gas stream at a first temperature and typically at a pressure of at least 30 barg with a CO2 sorbent comprising an ionic liquid containing a potentially nucleophilic carbon atom bearing a relatively acidic hydrogen atom bonded to a potentially nucleophilic carbon atom to sorb CO2 into the solution and regenerating the ionic liquid absorbent by treating the sorbent under conditions including a second, typically higher, temperature, to cause desorption of at least a portion of the CO2 and to regenerate the ionic liquid.

  • Patent number: 9115851
    Abstract: A method is provided for enhancing the shear stability of a high-viscosity fluid-water flow system, such as a core annular flow system. The method employs a family of demulsifier additives for maintaining separation of the fluids in biphasic flow. The additive family is sodium salts of polynuclear aromatic sulfonic acids. In one aspect, the high-viscosity fluid is heavy oil. A method to flow oil through a biphasic flow system is also provided. The method includes locating an oil in the biphasic flow system; placing water within the biphasic flow system; flowing the oil through the biphasic flow system within an annular flow of water; and subjecting the water in the biphasic flow system to a salt of a polynuclear aromatic sulfonic acid additive so as to improve shear stability of the oil and water.

  • Patent number: 7128150
    Abstract: This invention is method of recovering gas from a gas-bearing subterranean formation in which gas is produced from an upper portion of the formation and a waste gas is injected into a lower portion of the formation to dispose of the waste gas. The waste gas is injected within a 3000 foot (914 m) radial distance from the production of the gas. The injection and production can be carried out using one well or a plurality of wells.

  • Patent number: 6755251
    Abstract: The invention is a method and system of separating a multi-component fluid in a wellbore. At least one fluid separation membrane comprising a feed side and a permeate side is incorporated in the wellbore. A flowing stream of the multi-component fluid obtained from a subterranean zone being in fluid communication with the wellbore is passed across the feed side of the membrane at a first pressure. A retentate stream depleted in at least one component compared to the multi-component fluid is withdrawn from the feed side of the membrane and passed to the earth's surface. A permeate stream at a second pressure is withdrawn from the permeate side, in which the permeate stream is enriched in at least one component compared with the multi-component fluid. The second pressure is controlled to maintain the second pressure below the first pressure.
