1. A method for removing elemental mercury from a natural gas condensate feed comprising:
introducing the natural gas condensate feed into a stabilizer column;
operating the stabilizer column at conditions in which mercury is transferred from a stabilized condensate phase to an overhead gas phase;
compressing the overhead gas phase having the transferred mercury; and
recycling the compressed overhead gas phase with the transferred mercury to one or more gas-phase mercury removal units located upstream of one or more liquefaction units.
