Abstract:
Methods and apparatuses for reducing the effects of motion in a core-in-shell type heat exchanger are provided. One apparatus includes: (a) a heat exchanger, wherein the heat exchanger includes an internal volume defined within a shell and a plurality of spaced apart cores disposed within the internal volume of the shell, wherein the internal volume is flooded with a vaporizing fluid; and (b) a separation vessel connected to the heat exchanger, wherein the separation vessel is located at higher elevation than the heat exchanger, wherein the separation vessel is connected to the heat exchanger in such a manner so as to deliver a hot feed stream to heat exchanger and the receive a non-vaporizing stream from the heat exchanger.
Abstract:
Apparatuses and methods for suppressing slosh in a core-in-shell type heat exchanger are provided. One embodiments provides a heat exchanger including: (a) an internal volume defined within a shell; (b) a plurality of spaced apart cores disposed within the internal volume of the shell, and (c) slosh suppressing baffles disposed within the internal volume to separate the plurality of spaced apart cores, wherein each core is partially submerged in a liquid shell-side fluid, wherein the slosh suppressing baffles allow limited distribution of the liquid shell-side fluid between each core, wherein the slosh suppressing baffles can withstand cryogenic temperatures, wherein the slosh suppressing baffles can withstand and divert the flow of the liquid shell-side fluid between each core.
