ABSTRACT:
LNG facility employing one or more vertical core-in-kettle heat exchangers to cool natural gas via indirect heat exchange with a refrigerant. The vertical core-in-kettle heat exchangers save plot space and can be use to reduce the size of cold boxes employed in the LNG facility. In addition, vertical core-in-kettle heat exchangers can exhibit enhanced heat transfer efficiency due to improved refrigerant access to the core, improved refrigerant circulation around the core, and/or improved vapor/liquid disengagement above the core.
