MVC Evaporator Technology To Treat And Reuse Produced Water From A SAGD Facility

Source: Aquatech International Corporation

The SAGD Facility is called “Orion” and consists of 4 major processes: Steam Generation, Injection/Recovery Wells, Deoiling and Water Purification, for recovery of oil.

SAGD (Steam Assisted Gravity Drainage) is a technique to recover bitumen from the oil sands formation. The oil is recovered by further processing and upgrading the recovered bitumen. These formations are called Oil Sands as the bituminous resource is mixed with sand in the formation.

The liquid that is pumped to the surface is a mixture of oil and water. The mixture is separated to a predominantly oil and water fractions in the deoiling process. From there, the oil fraction is sent to Upgrader and refineries for conversion into a saleable product. The water fraction is sent to the Aquatech system for purification and reuse in the facility. Once purified, the water is used as feed to the boiler for generation of Steam for injection into the formation and the cycle continues.
