Patent ID: 8850818

Claim:
A system for supplying fuel to a gas turbine, the system comprising: at least one flow channel configured to provide a fuel; one or more sensing devices configured to determine one or more parameters associated with the fuel, wherein the determined one or more parameters comprise a composition of the fuel; a pressure changing device configured to receive the fuel from the at least one flow channel and reduce a pressure of the fuel to a desired pressure; a separator connected downstream of the pressure changing device and configured to remove liquids from the fuel; and at least one controller configured to (i) receive the determined one or more parameters from the one or more sensing devices, (ii) calculate, based at least in part upon the one or more parameters, the desired pressure, wherein the at least one controller is configured to calculate the desired pressure by: directing, based at least in part on the composition, a calculation of a hydrocarbon dew point analysis for the fuel; identifying, based at least in part on the hydrocarbon dew point analysis, a condensate concentration to pressure ratio for the fuel along an expansion path associated with the fuel; and calculating the desired pressure based at least in part upon the calculated condensate concentration to pressure ratio; and (iii) direct the operation of the pressure changing device to achieve the desired pressure.
