Abstract: Methods and systems of operating an integrated gasification combined cycle system are provided. The method includes coupling a non-fuel fluid conduit to a fuel conduit, warming a flow of non-fuel fluid, and channeling the warmed non-fuel fluid through the fuel conduit such that heat from the warmed non-fuel fluid heats the fuel conduit to a predetermined temperature.

Abstract: The present invention provides a much safer solution to pressurizing oxygen-containing gas feed lines at the start up of an oxygen-containing gas using process unit. All piping downstream of the main oxygen-containing gas block valve is pressurized with inert nitrogen prior to introducing the oxygen-containing gas into the piping. By equalizing with nitrogen it removes the hazard of slowly pressurizing the piping with the oxygen-containing gas and exposing the oxygen-containing gas to the substantial pressure drop associated with pressurizing piping to a high pressure.
