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 The withdrawn methane refrigerant is then cooled in an auxiliary heat exchange system by indirect heat exchange with a refrigerant that is also used to cool the natural gas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.
