GE의 진보된 증발기와 Zero liquid discharge(ZLD) 기술은 남부 이탈리아 지역의 Basilicata에 6개의 Total E&P Italia SpA 유전에서 생산되는 물의 98% 재활용하는데 사용된다.

 5월 5일 IFAT Entsorga 2014 박람회 기간동안 공학, 조달, 건설 계약자인 Maire Tecnimont SpA는 GE를기술 제공자로 발표했다. GE는 두 개의 동일한 탈유 설비를 포함하는 생산수 처리시설과 강제순환 염분 압축, ZLD을 위한 결정화와 증발기를 제공할 예정이다. 압축과 결정화를 위해 사용되는 GE의 다양한 효과의 증기 이동 장치는 매우 복잡한 공정이다.

GE's advanced evaporator and zero liquid discharge (ZLD) technology is to be used to recycle up to 98% of produced water at six Total E&P Italia SpA oilwells in the Tempa Rossa field in the Basilicata region of southern Italy.

Engineering, procurement and construction contractor Maire Tecnimont SpA, which is overseeing the development of the project for Total E&P Italia, chose GE to provide the technology, the company announced during the IFAT Entsorga 2014 exhibition on 5 May 2014.

GE will provide two identical produced water treatment units including de-oiling, forced circulation brine concentration, evaporation and crystallization for ZLD. It is a complex process in which GE's multiple-effect steam-driven units will be used for concentration and crystallization.

Vapors generated during the evaporation process are condensed in GE air condensers and coolers to meet the required temperature for demineralized water production and firefighting reuse.

The energy-efficient technology will treat up to 52 m³/h of feed water per line and will recover the produced water as distillate and solids. Completed delivery is expected by the first quarter of 2015 with installation by the third quarter of 2015.

The project marks the first application of GE-produced water treatment in Europe, leveraging on GE's wide experience in produced water treatment in Canada, the US and Australia.
