Gas pressure reduction generator

摘要

Gas Pressure Reduction Generator (GPRG) systems and methods for implementing a GPRG system are provided, where the GPRG systems comprise a gas inlet configured to receive a pressurized gas flow, at least one expander in gas flow receiving communication with the gas inlet wherein the expander is operable to convert the pressurized gas flow into mechanical energy and a depressurized gas flow, and a generator configured to convert the mechanical energy into electrical energy.

1. A gas pressure reduction generator system comprising in combination:
A. a pressurized gas flow inlet; B. at least one lubricated pressurized gas expander having (i) a pressurized gas expander inlet in pressurized gas flow communication with the pressurized gas flow inlet and (ii) a reduced pressure gas outlet; C. a lubrication oil separator/reservoir in lubrication oil receiving communication with the reduced pressure gas outlet; D. a lubrication oil pump in lubrication oil receiving communication with the lubrication oil separator/reservoir and in lubrication oil sending communication with the expander; E. one or more lubrication oil heaters interposed (i) between the reduced pressure gas outlet and the lubrication oil separator/reservoir, (ii) between the lubrication oil separator/reservoir and the lubrication oil pump, or (iii) between the reduced pressure gas outlet and the lubrication oil separator/reservoir and between the lubrication oil separator/reservoir and the oil pump, wherein the temperature of the lubrication oil is increased upon passage through at least one lubrication oil heater; and F. a power generating generator in rotational generator driving communication with the pressurized gas expander.
