Oil sands produced water evaporator blowdown (waste) volume reduction and solidification

R&d program integrating ide's unique horizontal evaporator technology with saltworks expertise in volume reduction and solidification of highly impaired water. The combined evaporation-solidification process will increase water re-use and decrease disposal volumes in sagd production process.

Alberta's Oil Sands Steam Assisted Gravity Drainage (SAGD) Produced water treatment is highly challenging due to the quality of the water, the requirement for recycling more than 90% of the water for re-use, and the limited disposal options on-site. Developing a more reliable, sustainable and cost effective water treatment process is one of the key market goals. MVC evaporators are a critical step in the SAGD water treatment process, recovering ~95% of the water and providing boiler feed water quality. Currently, the options for volume reduction and solidification of the evaporator blowdown (waste) stream are limited and not reliable. Many SAGD sites cannot dispose of the evaporator waste on-site, and have to pay millions of dollars per year to "truck" (transport) the waste stream to a dedicated disposal well. The objective of this R&D project is to develop and validate a cost-effective combined evaporation-evaporation waste treatment process that will increase the overall water recovery and decrease the disposal volumes in SAGD production. The joint development will focus on optimizing a zero liquid discharge (ZLD) process, treating produced water all the way to solids, while achieving maximal availability and reliability of each step and insuring minimal downtime. The design project will include the use of an evaporator developed by IDE, which can operate either on electrical power (MVC), or on steam (MED), which provides significant energy savings. Saltworks will develop a Saltmaker unit, which includes corrosion resistant non-stick engineered plastics, intelligent self cleaning operation, and reliable solids extraction. The R&D project will include a six months bench-scale Piloting program at the Alberta Innovates Technology Futures (AITF) applied research facility in Edmonton, starting March, 2015.
