Abstract

A fluid bypass method for controlling the temperature of a non-petroleum fuel, the fluid bypass method includes: providing a fuel at a pressure sufficient to effect a desired flow rate to a vehicle, the fuel being at a liquid or substantially supercritical thermodynamic state requiring further heat addition in a vaporizer; and diverting a bypass stream with partial or no vaporization to a heat exchanger as a cold fluid on a cold side of the heat exchanger. The method further includes providing a remainder stream of the fuel to the vaporizer; mixing the remainder stream outflowed from the vaporizer with the cold fluid outflowed from the cold side of the heat exchanger to form a combined fuel stream; and providing the combined fuel stream to the heat exchanger as a warm fluid on a warm side of the heat exchanger.
