摘要： 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.

摘要： A method for dispensing liquefied fuel, the method including: providing a non-petroleum fuel as a liquefied fuel to a storage tank; increasing pressure of the liquefied fuel to a target pressure using a pump disposed within the storage tank, where a first portion of the liquefied fuel is bypassed around or at least partially around a heat exchanger, and a second portion of the liquefied fuel is discharged to the heat exchanger, where the heat exchanger is configured to warm the second portion of the liquefied fuel. A dispenser is provided that incorporates a control system that allows coordinated fueling of one or more vehicles simultaneously, where the heat exchanger uses only the fuel itself without external refrigeration to manage final dispensing temperature and the fueling station does not include a storage subsystem disposed between the pump and the dispenser.

摘要： An isolation mechanism for isolating a submerged pump in a storage vessel, where the isolation mechanism comprises a primary valve member and a secondary valve member, which are both biased in a fail-closed position. The isolation mechanism allows for redundancy for safety and reliability, and can be operated externally of the storage vessel. Furthermore, the isolation mechanism comprises venting and purging devices for safe operation of removal and installation of the pump in the storage vessel.
