Systems and methods for mixing and dispensing gas at a controlled temperature using cryogenic fluid

A system for mixing and dispensing fuel, comprising:

• a first temperature adjustment loop connected to a second temperature adjustment loop, the first temperature adjustment loop comprising:
• a storage tank configured to hold a fuel,
• a process heat exchanger located downstream from the storage tank and having a cold portion and a warm portion, and
• a first vaporizer having an inlet and an outlet, the inlet connected to the cold portion of the process heat exchanger and the outlet connected to the warm portion of the process heat exchanger;
• and
• the second temperature adjustment loop comprising:
• a first flow path including a second vaporizer, and
• a second flow path bypassing the second vaporizer, the first flow path and second flow path connected downstream to a third flow path, the third flow path connected to at least one dispenser.

A system for mixing and dispensing fuel, comprising:

• a first temperature adjustment loop connected to a second temperature adjustment loop, the first temperature adjustment loop comprising:
• a storage tank configured to hold a fuel,
• a process heat exchanger having a cold portion and a warm portion,
• a pump coupled to the storage tank and configured to pump fuel from the storage tank to the cold portion of the process heat exchanger,
• the cold portion of the process heat exchanger connected to an inlet of a first vaporizer, and the warm portion of the process heat exchanger connected to an outlet of the first vaporizer, the fuel passing from the cold portion of the process heat exchanger to the inlet of the first vaporizer, through the first vaporizer, and from the outlet of the first vaporizer to the warm portion of the process heat exchanger;
• and
• the second temperature adjustment loop comprising:
• a control valve having a passage, the passage having a first opening and a second opening, the first opening coupled to the warm portion of the process heat exchanger and the second opening coupled to a first flow path and a second flow path, the control valve configured to separate the fuel received from the process heat exchanger into a first stream and a second stream, the control valve controllably permitting fuel from the first temperature adjustment loop to enter the second temperature adjustment loop,
• the first flow path including a second vaporizer, and
• the second flow path bypassing the second vaporizer,
• the first flow path and the second flow path connected to a mixing valve, the mixing valve located upstream from at least one dispenser,
• the mixing valve configured to receive and mix the fuel from the first flow path and the second flow path, and
• the dispenser configured to receive and dispense the fuel after the fuel has been mixed.
