Assignee:

Energent Corporation - Santa Ana CA

International Classification:

F25D 900

US Classification:

62402, 62498, 62467, 62 87

Abstract:

A process employing a rotary axial turbine, and a nozzle, that includes providing a working fluid expansible from a characteristic supercritical region into the wet region, expanding the fluid from said supercritical region into the wet region via the nozzle and turbine blades, and providing an output shaft driven by the turbine.

Appl. No.:

10/087917

Inventors:

Emilio Castano Graff - Torrance CA
Lance G. Hays - Placentia CA

Assignee:

Energent Corporation - Santa Ana CA

International Classification:

B01D 4514

US Classification:

95 35, 95270, 55343, 55345, 55394, 55404, 55406, 96314

Abstract:

A gas centrifuge operating to separate gases of differing chemical composition and molecular weight by a centrifugal force field. Such a centrifuge is operable to separate methane and carbon dioxide, and to produce torque, and a cascade of such centrifuges is operable to concentrate produced streams of carbon dioxide and methane, and to produce torque. A compact centrifugal gas processing system incorporating the gas centrifuge with other centrifugal components, is also provided.

Duane Bergmann - Big Bear CA

Assignee:

Energent Corporation - Santa Ana CA

International Classification:

F01K 2304

US Classification:

60655, 60670, 60682

Abstract:

A waste heat recovery system comprising ducting to which hot gas is communicated, means to supply lower temperature diluent gas to the ducting, to mix with the hot gas, and produce a reduced temperature mixed gas stream, a vaporizer in communication with the ducting, to receive the stream and to transfer heat from the stream to a working fluid in the vaporizer to vaporize said fluid, and a blower operating to displace the stream through the vaporizer.

Appl. No.:

10/424897

Inventors:

Lance Hays - Tustin CA, US
Ross Brown - Murrieta GA, US
Ronald Franz - Rancho Santa Margarita CA, US

Assignee:

Energent Corporation - Santa Ana CA

International Classification:

B01D005/00

US Classification:

95153, 95217, 95219, 95226

Abstract:

A separation process, the steps that include: providing an expansion zone, flowing a gaseous fluid into and through the expansion zone, flowing a spray of liquid droplets into the expansion zone to mix with the gaseous fluid and produce nucleation sites, then expanding the flow of mixed gaseous fluid and liquid droplets to cause condensation of gas onto the liquid droplets, and then centrifuging liquid droplets into a separation layer.

Appl. No.:

10/196263

Inventors:

Lance G. Hays - Placentia CA, US

Assignee:

Energent Corporation - Santa Ana CA

International Classification:

F28F027/00

US Classification:

165274, 62197, 622386, 60651, 60653, 60655

Abstract:

A high temperature heat pump comprising a low temperature heat exchanger to produce vapor of a first fluid from heat transferred from a second fluid to a mixture of liquid and vapor of the first fluid; a compressor to increase the pressure and temperature of the produced vapor; a high temperature heat exchanger to heat the second fluid to useful, high temperatures from the condensation of the first fluid; and an expander to lower the pressure and temperature of the first fluid producing a mixture of vapor and liquid.

Dicran Sahabian - Los Angeles CA, US

Assignee:

Energent Corporation - Santa Ana CA

International Classification:

G01F 1/05

US Classification:

Appl. No.:

11/013073

Inventors:

Lance G. Hays - Tustin CA, US

Assignee:

Energent Corporation - Santa Ana CA

International Classification:

F01D 1/06
F01D 3/00

US Classification:

415 84, 415106, 4151731, 4151735

Abstract:

A turbine, including a rotor on a shaft, and having in combination stationary nozzles discharging steam at a first pressure or pressures thereby producing impulse forces on the rotor; internal passages in the rotor producing a pressure head increase in the discharged steam, while simultaneously accelerating the steam, the steam discharged to a second pressure lower than the first pressure, producing reaction forces on the rotor; seal means between the stationary nozzles and the rotor, maintaining the pressure difference between the first pressure and the second pressure while minimizing steam leakage past the internal passages, turbine operations producing shaft power.
