MEG Energy Corp has selected GE evaporation technology for reusing steam generator water for boiler feed in a bitumen extraction project in Alberta, Canada.
The Christina Lake project uses both cogeneration and once-through steam generators (OTSGs) to drive the steam-assisted gravity drainage (SAGD) process for the production of bitumen from oil sands.
GE's evaporators will be used to recycle a significant portion of the steam generator blowdown for Phases 2B and 3A of the project rather than disposing of it by deep well injection. GE will supply fifth generation, fully modularized evaporator systems, which are designed to achieve the lowest possible project costs.
"We've witnessed industry trends of SAGD projects either installing new systems with OTSG evaporators or retrofitting existing units. As projects in Alberta's oil sands increase, more companies are turning to GE's evaporative technologies to address the critical issue of how to handle produced water," said Bill Heins, general manager, thermal systems--water and process technologies for GE Power & Water
