Publication number: 20140060413Abstract: A mooring component comprises a plurality of different deformable elements formed of an elastomeric material. The component has a tensile length L and at least one of the elements has a length L?<L. As the mooring component comprises a plurality of different elastomeric elements, each having its own unique elastic (i.e. reversible) stress-strain response, the overall response of the component is a composite elastic response resulting from a combination of the responses of each of the plurality of elastomeric elements. The mooring component can form part of a mooring system for floating devices and sea-based structures such as renewable energy devices, including wave energy conversion devices, tidal turbines and tidal platforms, fish farms, oil rigs and off-shore wind farms, especially in low scope or high variability environments.Type: ApplicationFiled: March 22, 2012Publication date: March 6, 2014Inventor: Paul McEvoy

Patent number: 8661830Abstract: A hybrid multichannel porous structure for processing between two fluid streams of different compositions includes a housing and one or more structures disposed within the cavity of the housing in a shell and tube configuration. Each structure includes a body made of a porous, inorganic material and a plurality of channels for processing an optional sweep stream. Each channel is coated with a membrane layer. A feed stream introduced into the housing is in direct contact with the structures such that a gas selectively permeates through the body and into the channels. The gas combines with the sweep stream to form a permeate that exits from each channel. The remaining feed stream forms a retentate that exits from the housing. The feed stream may consist of syngas containing hydrogen gas and the sweep stream may contain nitrogen gas. A power plant that incorporates the hybrid structure is disclosed.Type: GrantFiled: November 2, 2009Date of Patent: March 4, 2014Assignee: General Electric CompanyInventors: Anthony Yu-Chung Ku, Kevin Paul McEvoy, Patrick Daniel Willson, Parag Parkash Kulkarni, Roger Allen Shisler, Anoop Muralidhara Kurup

Patent number: 8647997Abstract: A free-standing zeolite membrane and a zeolite membrane supported on a support structure are disclosed. The free-standing zeolite membrane is fabricated by mixing zeolite particles and an optional inorganic binder, forming a green body, and sintering the green body at a sufficiently low temperature so as to prevent damage to the gas selectivity properties of the zeolite particles. The supported composite zeolite membrane is fabricated by mixing a sacrificial binder, an optional inorganic binder, boehmite sol and zeolite particles to form a slurry. The slurry is then coated onto a porous support structure, dried and sintered at a sufficiently low temperature so as to prevent damage to the gas selective properties of the zeolite particles. In both membranes, the zeolite particles span the entire thickness of the membrane to provide a high selectivity path for the flow of gas to pass therethrough.Type: GrantFiled: November 30, 2010Date of Patent: February 11, 2014Assignee: General Electric CompanyInventors: Kevin Paul McEvoy, Hrishikesh Keshavan, Anthony Yu-Chung Ku, Steven Mitchell Kuznicki, Weizhu An, Lan Wu, Paul Donald Swenson

Publication number: 20120325744Abstract: In a process and apparatus for treating produced water, for example for re-use in an oil or bitumen extraction operation of for treating frac water, the produced water flows through a series of treatment units. A portion of the produced water may by-pass one or more of the treatment units but the by-pass portion may be such that the treated water is still acceptable, for example for discharge or reuse. Concentrations of oil and grease, organic carbon, silica, pH or related parameters in the produced water may be monitored and used to control the process or apparatus. Control of the process may involve one or more of altering a by-pass portion, altering the addition of chemicals, and altering the operation of a unit process. The process may be controlled to respond to upset conditions, or such that the concentration of one or more limiting contaminants is near, but not over, a specified maximum for re-use or discharge.Type: ApplicationFiled: June 22, 2011Publication date: December 27, 2012Inventors: David M.
