QUA has been awarded a contract to supply its FEDI fractional electrodeionization (EDI) technology for the reverse osmosis permeate polishing demineralizing process to support Cheniere Energy’s addition of liquefaction services to its Sabine Pass LNG Terminal.
This project is the third phase of expansion to supply water to the facility’s liquefaction operations and will add an additional 30% capacity to the water plant. FEDI was also used in the previous two phases. This brings the total water flow rate at this plant to 4,185 gpm, making it one of the largest EDI systems installed in the world.
The water is used for injection for compressor turbines for methane, propane and ethylene; wash water for gas turbines and other utility make-up uses. The feed water to the terminal is from a local utility, and the water requires further treatment to produce high purity water with low conductivity and silica content for the plant’s uses.
