Title:

SYSTEM AND METHOD FOR CONTROLLING AN EXPANSION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2009/079203

Kind Code:

A3

Abstract:

A control system includes a temperature sensor (32) communicatively coupled to an exit of an expander (18) of an expansion system and configured to detect temperature of the working fluid flowing through the exit of the expander. A pressure sensor (34) is communicatively coupled to the exit of the expander (18) and configured to detect pressure of the working fluid flowing through the exit of the expander. A controller (36) is configured to receive output signals from the temperature sensor (32) and the pressure sensor (34) and control operation of one or more components of the expansion system so as to control the thermodynamic conditions at the exit of the expander (18) while driving a quality of vapor of the working fluid at the exit of the expander towards a predetermined degree of superheat.
