Abstract
The present invention is directed to a method for removing elemental mercury from liquid natural gas comprising changing the stabilizer column operating conditions to beneficially transfer mercury from the stabilized condensate phase to the overhead gas phase, where it may be compressed and recycled with the gas going to the existing feed gas mercury removal units.
Claims7
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.
