Three-shell cryogenic fluid heater

摘要

Systems and methods for heating a cryogenic fluid are provided. A cryogenic fluid can be heated to provide a partially cryogenic vaporized fluid having a first temperature. The partially vaporized cryogenic fluid can be partially vaporized to provide a second partially vaporized fluid having a second temperature. At least a portion of the second, partially vaporized, cryogenic fluid can be used to heat the cryogenic fluid to the first temperature. The second, partially vaporized, cryogenic fluid can be partially vaporized to provide a substantially vaporized cryogenic fluid having a third temperature.

1. A method for vaporizing a fluid, comprising:
heating a fluid to a first temperature sufficient to at least partially vaporize the fluid and produce a partially vaporized fluid at the first temperature; heating the partially vaporized fluid at the first temperature to a second temperature of about −165° C. to about −50° C. to increase the vapor content of the partially vaporized fluid; recycling a first portion of the partially vaporized fluid at the second temperature, comprising:
heating the fluid to the first temperature with heat from the first portion of the partially vaporized fluid; andcooling the first portion of the partially vaporized fluid to produce a cooled fluid; and heating a second portion of the partially vaporized fluid at the second temperature and the cooled fluid to a third temperature, which is greater than the second temperature, to produce a substantially vaporized fluid at the third temperature, wherein the first portion of the partially vaporized fluid at the second temperature has the same composition as the partially vaporized fluid at the first temperature and the second portion of the partially vaporized fluid at the second temperature.
