QUA는 텍사스와 루이지애나주 경계에 위치한 대규모 액화천연가스(LNG) 플랜트에 RO 침투 폴리싱에 대한 분자 전기탈이온장치(FEDI, fractional electrodeionization)를 공급하는 계약을 체결했다.

이 프로젝트는 체니에르 에너지(Cheniere Energy)의 사빈패스(Sabine Pass) LNG 터미널에 대한 액화 서비스 구성에 물을 공급하는 3단계 확장 프로젝트로, 시간당 951㎥까지 유량을 확보함으로써 수처리 플랜트의 용량을 30% 늘릴 것으로 기대된다. FEDI는 앞선 두 단계에 설치된 바 있다.

 

 

 

QUA has won a contract to supply its fractional electrodeionization (FEDI) technology for reverse osmosis (RO) permeate polishing at a major liquified natural gas (LNG) plant on the Texas-Louisiana border.

 

The project is the third phase of expansion to supply water to Cheniere Energy's addition of liquefaction services to its Sabine Pass LNG terminal. It will add 30% to the capacity of the water plant, taking the flow rate to 951m³/hr making it one of the largest electrodeionization systems installed in the world, QUA claimed. FEDI was deployed in the previous two phases.

 

The water is used for compressor turbines for methane, propane and ethylene; wash water for gas turbines and other utility make-up uses. These processes demand that the local utility feed water to the terminal receives further treatment to produce high purity water with low conductivity and silica content.

 

"This project is a great showcase for the dual voltage fractional electrodeionization process. It really demonstrates on a large scale how well the technology can perform downstream of a single pass RO system," said QUA's director of sales and marketing, Fred Wiesler.
