QUA’s FEDI Chosen for LNG Refinery

Project Background: A large LNG refinery in the United States required a membrane desalination solution to cater to its extensive process water needs in order to produce a large amount of liquefied natural gas for export.

The customer decided that a reverse osmosis (RO) desalination solution, followed by a demineralization step, would best suit their intended system designed to operate on single pass RO feed water.

Since single pass RO water is a challenging applicationfor conventional EDI systems, the customer carefully evaluated options for RO permeate polishing.

QUA’s FEDI was chosen due to its design advantages that include reduced hardness scaling.
