Abstract
A cryogenic vaporization system and method are provided. A first heat exchanger heats a liquid cryogen via indirect heat exchange to output a cryogenic vapor at a first temperature. A second heat exchanger receives the cryogenic vapor at the first temperature. The second heat exchanger heats the cryogenic vapor via indirect heat exchange to a second temperature. The cryogenic vapor at the second temperature is recirculated to the first heat exchanger to heat the liquid cryogen and cool the recirculated cryogenic vapor to a third temperature. A third heat exchanger receives the cryogenic vapor at the third temperature. The third heat exchanger heats the cryogenic vapor to a fourth temperature. The third heat exchanger outputs the cryogenic vapor at the fourth temperature.
