Method and apparatus for reducing the impact of motion in a core-in-shell heat exchanger

A method for reducing the impact of motion in a heat exchanger comprising:

• a. flooding the heat exchanger with a vaporizing fluid, 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;
• b. introducing a hot process feed stream to a separation vessel, wherein the separation vessel is located above the heat exchanger, wherein the separation vessel is connected to the heat exchanger via a plurality of external pipes;
• c. delivering the hot process feed stream to a core within the internal volume of the shell via the external pipes, wherein the hot process feed stream undergoes indirect heat exchange with the vaporizing fluid thereby producing a warm liquid stream and a non-vaporized stream, wherein the non-vaporized stream is a mixture of vapor and liquid;
• and
• d. delivering the non-vaporized stream to the separation vessel to undergo separation.

• b. introducing a hot process feed stream to a separation vessel, wherein the separation vessel is located at an elevation higher than the heat exchanger, wherein the separation vessel includes a liquid outlet and a vapor inlet;
• c. delivering the hot feed stream to a core within the internal volume of the shell at or near the top of the core via the liquid outlet, wherein the hot feed stream undergoes indirect heat exchange with the vaporizing fluid thereby producing a warm liquid stream and a non-vaporized stream, wherein the non-vaporized stream is a mixture of vapor and liquid;
• and
• d. delivering the non-vaporized stream to the separation vessel to undergo separation.
