Apparatuses and methods for controlling the temperature of a process fluid

摘要

The present invention provides apparatuses and methods for controlling the temperature of a process fluid. An exemplary apparatus in accordance with the present invention comprises a process fluid tank, a cryogenic fluid tank, and a plurality of heat transfer plates for transferring heat from a process fluid in the process fluid tank to a cryogenic fluid in the cryogenic fluid tank. Heating devices can be used to heat a portion of one or more of the heat transfer plates to regulate the transfer of heat from a process fluid in the process fluid tank to a cryogenic fluid in the cryogenic fluid tank.
