  • Publication number: 20080022716
    Abstract: An improved apparatus and method for providing reflux to a refluxed heavies removal column of a LNG facility. The system withdraws a fraction of a predominately methane refrigerant from a methane refrigeration cycle of the LNG facility. The withdrawn methane refrigerant is then cooled in an auxiliary heat exchange system by indirect heat exchange with a refrigerant that is also used to cool the natural gas feed stream upstream of the heavies removal column. The resulting cooled predominately methane steam is then employed as reflux to the heavies removal column.

  • Patent number: 7310971
    Abstract: An improved apparatus and method for providing reflux to a refluxed heavies removal column of a LNG facility. The apparatus comprises stacked vertical core-in-kettle heat exchangers and an economizer disposed between the heat exchangers. The reflux stream originates from the methane-rich refrigerant of the methane refrigeration cycle. The liquid reflux stream generated by cooling the methane-rich stream in the vertical heat exchangers via indirect heat exchange with an upstream refrigerant.
