Appl. No.:

10/652609

Inventors:

Gordon T. Rivers - Houston TX, US
Daniel L. Crosby - Sugar Land TX, US

Assignee:

Baker Hughes Incorporated - Houston TX

International Classification:

C07C 9/00

US Classification:

585 15, 585950, 95153, 166310, 166371, 137 3, 137 13, 507 90

Abstract:

A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule involves adding a reaction product to the mixtures in an effective amount to inhibit formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the reaction product. The product is made by the reaction of first reactant that is an amine or polyamine, or alcohol or polyalcohol, with a second, aldehyde reactant and a third reactant that is an alcohol or polyalcohol or, an amide or polyamide. Preferably, if the first and third reactants are both an alcohol or both a polyalcohol, they are not the same. A non-limiting example of a suitable amine would be a fatty alkyl amine, while formaldehyde would be a non-limiting of a suitable aldehyde and polyacrylamide would be a suitable third reactant.

Abstract:

A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule has been discovered that involves adding a composition to the mixtures in an amount that is effective in inhibiting formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the reaction product. The composition includes at least one dendrimeric compound having a number average molecular weight of at least 1,000 atomic mass units (amu); and at least one small molecular weight species having less than 1,000 amu, selected from the group consisting of polyalkyleneimine, polyallylamine, starch, sugars, and polymers or copolymers of vinyl alcohol or allyl alcohol; and, optionally, at least one surfactant.

International Classification:

C07C009/00

US Classification:

585015000

Abstract:

A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule involves adding an ion pair to the mixtures in an amount effective to inhibit formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the ion pair. In one non-limiting embodiment of the invention the ion pair includes a cationic component that may be a quaternary ammonium compound or an onium compound and a non-cationic counter-ion component that could be an anionic compound, a non-ionic compound and/or an amphoteric compound. Two specific, suitable non-cationic counter-ion components include sodium dodecyl sulfate and ammonium alkyl ether sulfate.

International Classification:

E03F 1/00
E03F 5/10

Abstract:

An example system includes a valve between a suction pipe extending into a sewage pit and a vacuum pipe connected to a sewer system. The vacuum pipe has vacuum pressure. The valve is controllable to open to allow content to flow from the sewage pit, through the suction pipe, and into the vacuum pipe. A sensor is configured to detect the vacuum pressure in the vacuum pipe. The valve is controllable to open for a duration that is based, at least in part, on the vacuum pressure in the vacuum pipe.

Abstract:

An example apparatus is for use in a system that includes a sewage pit, a suction pipe in the sewage pit, and a valve between the suction pipe and a vacuum pipe that connects to a sewer system. The apparatus includes a controller configured to perform operations that include: detecting a vacuum pressure in the vacuum pipe, determining that the vacuum pressure in the vacuum pipe is below a predefined pressure, and preventing the valve from opening in response to determining that the vacuum pressure in the vacuum pipe is below the predefined pressure.
