엔카나(Encana) 원유·가스기업이 와이오밍주(Wyoming) 모네타 구역에서의 오일샌드 유전으로부터 생산된 물을 처리하기 위한 RO 담수화 플랜트를 설계했다. 넵튠(Neptune) 수처리 플랜트는 엔카나가 보유한 모네타 구역에서 운영되는 300개의 원전 중 몇 곳에서 발생한 하루 4천㎥의 생산수를 처리한다.

 

 

 

Encana Oil and Gas has designed and commissioned a reverse osmosis (RO) desalination plant to treat produced water from its oil sand wells in the Moneta Divide, Wyoming. It has since sold the plant along with all its Moneta Divide assets to Aethon Energy.

 

The Neptune Water Treatment Plant has the capacity to treat 4,000 m3/d) of produced water, from some of the company's 300 wells operating in the Moneta Divide tight sands play.

 

GE Water & Process Technologies provided sand filters and the RO system with membranes from Dow Water and Process Solutions which provided also ion exchange resin and its Optipore hydrocarbon adsorbent.

 

GE said the system will handle feedwater total dissolved solids (TDS) at 7,500 mg/l to 13,500 mg/l with total suspended solids (TSS) at 10 mg/l to 500 mg/l to provide a 90% recovery. Treated water with a TDS below 250 mg/l is reused in the filed while the rest is piped to the Boysen reservoir.
