| SAGD Produced Water Recycling |
 Oil Sands in-situ production is being revolutionized with the introduction of Steam Assisted Gravity Drainage (SAGD) production methods. SAGD uses horizontal well pairs to extract crude bitumen from the oil sands reservoir. In the production process, hot steam is injected into the reservoir using the upper well, and the reduced viscosity bitumen is pumped out of the reservoir from the lower well. A large amount of water is brought up to the surface with the bitumen, which must be separated from the bitumen prior to further bitumen processing. The produced water contains dissolved material that must be removed before it can be recycled as steam.
Aqua-Pure's Evaporator technology is well suited to recycle produced water directly from the skim tank so that the water can be re-used as boiler feed water to make more steam. Our compact design significantly reduces overall facility footprint reducing capital cost. Aqua-Pure’s design is also resistant to scaling and fouling.When it becomes scaled it is much easier to service than conventional shell and tube evaporator systems, improving energy efficiency and reducing downtime.
Aqua-Pure currently has two SAGD Evaporator Installations and holds a joint patent with EnCana for a MVR Evaporator with a waste heat recovery system.
