Filed:

Jun 14, 2007

Appl. No.:

12/305636

Inventors:

Ramesh Varadaraj - Flemington NJ, US
Eugene R. Thomas - Houston TX, US

Assignee:

ExxonMobil Upstream Research Company - Houston TX

International Classification:

C09K 8/58

US Classification:

507259, 507258, 507263, 507265, 507276, 1663051

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 of transporting heavy oil through a tubular body is also provided. The method includes pumping the heavy oil through the tubular body within an annular flow of water, and subjecting the water in the tubular body to a salt of a polynuclear, aromatic sulfonic acid additive so as to improve shear stability of the heavy oil and water.

International Classification:

B01D 53/02

US Classification:

95 96, 95148, 96130

Abstract:

The present invention relates to the separation of one or more of CO, N, and HS gas components from a gas mixture containing at least a second gas using a swing adsorption process unit. The adsorbent contactors of the swing adsorption process unit are engineered structured adsorbent contactors having a plurality of flow channels wherein 20 volume percent or less of the open pore volume of the contactors is in the mesopore and macropore range.

US Classification:

95 96, 95148, 96130

Abstract:

The present invention relates the separation of a target gas from a mixture of gases through the use of engineered structured adsorbent contactors in pressure swing adsorption and thermal swing adsorption processes. Preferably, the contactors contain engineered and substantially parallel flow channels wherein 20 volume percent or less of the open pore volume of the contactor, excluding the flow channels, is in the mesopore and macropore range.

International Classification:

B01D 53/02

US Classification:

95 96, 95148, 96130

Abstract:

The separation of a target gas selected from a high pressure gas mixture containing said target gas as well as a product gas using a swing adsorption process unit. A turboexpander is used upstream of the swing adsorber to reduce the pressure of the high pressure gas mixture. A compressor is optionally used downstream of the swing adsorber to increase the pressure of the target gas-containing stream for injecting into a subterranean formation.

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.

International Classification:

C07L 4138

US Classification:

568621

Abstract:

The removal of a glycol contaminant from a mixture of polyalkylene glycol dialkyl ethers is achieved using a dual solvent extraction process. The process is particularly applicable to removing glycols which accumulate in recirculating solutions of polyalkylene glycol dialkyl ethers used for the absorption of acid gases from feedstocks such as natural gas, synthetic natural gas, refinery gas, and ammonia synthesis gas.
