  • Isolation valve for pressurized tank
    Patent number: 11149703
    Abstract: 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.
    Type: Grant
    Filed: September 9, 2019
    Date of Patent: October 19, 2021
    Assignees: China Energy Investment Corporation Limited, National Institute of Clean-and-Low-Carbon Energy
    Inventors: Kenneth William Kratschmar, Xianming Jimmy Li, Cullen Hall, Edward Youn, Jeff Allen
  • Method and system of dispensing liquefied gas
    Patent number: 11009185
    Abstract: 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.
