CALGARY, Alberta, June 11, 2013 /PRNewswire/ — Aquatech, a global leader in water purification technology for industrial and infrastructure markets, introduces the HEVAP™ high efficiency evaporation process for treating produced water from oil sands thermal processes such as Steam Assisted Gravity Drainage (SAGD).
"Increasingly, oil producers in Alberta are choosing to go with evaporation technology as the treatment method for reusing/recycling their produced water in thermal SAGD process because it offers a variety of benefits including higher water recovery rates (lower make-up / reduced blow down), smaller footprint, and easier operability. However, managing scaling has been a challenge with evaporation technology. Aquatech's HEVAP evaporative process addresses this issue as it has been engineered to operate in a scale-free environment while also providing other process advantages to oil producers," said Alan R. Daza, P.Eng., Vice President of Sales & Business Development for Aquatech's Infrastructure and Major Projects division.
The HEVAP evaporative process pre-conditions the feedwater by incorporating a softening step combined with additional conditioning of the feedwater prior to treatment by the evaporators. This process provides the evaporators with essentially a scale free environment in which to operate. Other advantages, which help lower operating expense (OPEX) and life cycle costs (LCC), include:
- High allowable concentration factors
- Increased recovery of high quality reusable water
- No requirement for anti-scalants
- No requirement for EDTA dosing
- No requirement for mechanical cleaning
"The HEVAP evaporative process significantly increases the level of operational reliability and availability, both of which are important requirements in any SAGD facility. As a result, we believe that this type of system offers great potential in the oil sands market," said Alan R. Daza, P.Eng., Vice President of Sales & Business Development for Aquatech's Infrastructure and Major Projects division.
