Once-Through Flash™

Home»Innovations»Once-Through Flash™

Good on water, good for oil.

Produced water management is essential for the sustainable development of oil and gas resources. Enhanced oil recovery projects that use Once-Through Steam Generators (OTSG’s) for steam production are often left with high volumes of disposal brine. Aquatech’s Once-Through Flash technology is designed to be paired with the OTSG’s to convert their blowdown water back into feed water.  Not only is the blowdown water recycled, but the thermal energy inherent in the blowdown water is also beneficially used to self-induce water recovery through evaporation.  As a result, the Once-Through Flash Evaporator Systems operate at power consumptions of 20-40% less than conventional evaporators.

Advantages

  • Maximizes OTSG Blowdown water recovery
  • Reduces operating expenses (OPEX) by 40%
  • No Steam required for ZLD applications
  • Satisfies Alberta Energy Regulator’s Directive 081
  • Lowers brackish & fresh water consumption
