Abstract
A system for removing a contaminant from a refrigerant stream employed in a closed-loop refrigeration cycle of an LNG facility. The system employs a distillation column to separate the refrigerant stream into a contaminant-rich and a contaminant-depleted stream, wherein the contaminant-depleted stream is subsequently returned to the closed-loop refrigeration cycle. The distillation column can include a reboiler and/or condenser. The reboiler and condenser can utilize one or more process streams from within the LNG facility to provide heating and/or cooling to the distillation column.
