Systems and methods for dispensing cryogenic liquid fuel as a gas at controlled temperature using cryogenic fluid

A system for mixing and dispensing fuel, comprising:

• a temperature adjustment loop connected to a mixing loop, the temperature adjustment loop comprising:
• a storage tank configured to hold a fuel,
• a first flow path configured to flow a first fuel stream of the fuel, the first flow path coupled upstream to the storage tank and coupled downstream to a warm portion of a process heat exchanger, the first flow path having a first vaporizer, and
• a second flow path configured to flow a second fuel stream of the fuel, the second flow path coupled upstream to the storage tank and coupled downstream to a cold portion of the process heat exchanger, the second flow path bypassing the first vaporizer;
• and
• the mixing loop comprising:
• a third flow path coupled upstream to the warm portion of the process heat exchanger and coupled downstream to a mixing point wherein the third flow path is configured to receive the first fuel stream from the warm portion;
• and
• a fourth flow path coupled upstream to the cold portion of the process heat exchanger and coupled downstream to the mixing point, wherein the fourth flow path is configured to receive the second fuel stream from the cold portion;
• wherein the first fuel stream and the second fuel stream are configured to be initially mixed at the mixing point to form a dispensing fuel stream, and
• a terminal flow path coupled upstream to the mixing point and coupled downstream to at least one dispenser.

A system for mixing and dispensing fuel, comprising:

• a temperature adjustment loop connected to a mixing loop, the temperature adjustment loop comprising:
• a storage tank configured to hold a fuel,
• a pump coupled to the storage tank and configured to pump fuel from the storage tank to a first flow path and a second flow path, the first flow path having a first vaporizer and the second flow path bypassing the first vaporizer, and
• a process heat exchanger having a warm portion and a cold portion, the first flow path coupled to the warm portion and the second flow path coupled to the cold portion to permit the fuel flowing through the first flow path to exchange heat with the fuel flowing through the second flow path;
• and
• the mixing loop comprising:
• a third flow path coupled upstream to the warm portion of the process heat exchanger and coupled downstream to a terminal flow path, the fuel flowing along the third flow path to the terminal flow path to mix with the fuel from the fourth flow path, and
• a fourth flow path coupled upstream to the cold portion of the process heat exchanger and coupled downstream to a terminal flow path, the fuel flowing along the fourth flow path to the terminal flow path to mix with the fuel from the third flow path;
• and
• the terminal flow path coupled downstream to at least one dispenser for dispensing the fuel.
