Abstract
A system and method for treating gas to fuel turbines by passing raw gas through an inlet pressure reducing valve to adjust the gas pressure and through a scrubber to capture liquids from the gas. Next, the gas is passed through a compressor to bring it to a pressure above that required by an inlet of a turbine and then to a post-compression aerial cooler that cools the gas to a temperature lower than a required dewpoint at fuel delivery pressure. Next, natural gas liquids are removed from the gas by passing it through a separator. A first portion of the cooled compressed gas is sent through a gas-to-gas heat exchanger, creating heated compressed gas, and a second portion of the cooled compressed gas passes through a backpressure valve. The heated compressed gas is blended with the second portion to create a fuel gas stream with a desired delivery temperature.
