Filed:

Jun 6, 2012

Appl. No.:

13/489708

Inventors:

Timothy Dyer - San Leandro CA, US
Mark Richter - Orinda CA, US
Rafael Andres Bañados Contreras - San Leandro CA, US
Chester L. Sandberg - Palo Alto CA, US

International Classification:

F01D 15/10

US Classification:

290 52

Abstract:

Systems and methods for combined flow control and electricity generation are described. Various embodiments may comprise an energy recovery device adapted to produce an electric current. At least a portion of the electric current may be used to power a pump. A control system may be adapted to adjust operating parameters of the system to stabilize or maximize the efficiency of the energy recovery device.

B01D 53/18

US Classification:

423210, 422187, 422113

Abstract:

A system includes a solvent gas processing system having a high pressure reaction vessel configured to remove an acid gas from an untreated feed gas using a solvent in a lean solvent fluid stream. The system includes a high pressure reaction vessel is configured to output a treated clean gas and a first flow of a high pressure fluid stream via a first flow path. The system includes a turbine having a main nozzle, an auxiliary nozzle, and an outlet. The main nozzle is configured to receive a second flow of the high pressure fluid stream from the first flow path via a main flow path. The system includes an auxiliary nozzle valve disposed along an auxiliary flow path. The auxiliary nozzle valve is configured to control a third flow of the high pressure fluid stream into the auxiliary nozzle of the turbine.
