Mechanical Vapour Recompression System (Evaporator)
Evaporation in SAGD produced water treatment.
Evaporation technology is an accepted method of treating oilfield produced water from SAGD (steam assisted gravity drainage) operations. This thermal process provides high-quality distillate as feed water for steam generation and allows the flexibility of using either traditional OTSGs (once-through steam generator) or drum-type boilers.
This produced water treatment system consists of Induced Gas Flotation (IGF) and Oil Removal Filter (ORF) technologies for the secondary de-oiling process. Our evaporators will then process the de-oiled produced water to provide high-quality water to the Once-Through Steam Generators (OTSG) as well as treat the resulting blow down.
The produced water treatment system is an example of the adoption of technologies and directives by APEC to minimize the impact of the Taiga Project on the surrounding environment. The evaporator system will recover over 93% of the water from SAGD operations for re-use in the process. More importantly, We will use no freshwater in the extraction process; instead using high salinity water for makeup demand for steam generation.
