The old adage ‘the whole is greater than the sum of its parts’ rings true for this project that demonstrated energy efficient technology at an Alberta pulp mill. The Grande Prairie Evaporator Project is the final addition to a clean energy overhaul.

This high efficiency evaporator system aimed to gather an additional 100,000 pounds of steam per hour to generate 23 megawatts of electricity. Together with the mill’s new recovery boiler and recently completed turbine, the combined project will reduce GHG emissions by more than 400,000 tonnes by 2020.

“Without the evaporator system, the combined project really isn’t efficiently compatible,” explains Wayne Roznowsky, then Manager of Public Affairs with Weyerhaeuser, who operated the facility at the time of the project.

“The ERA funding has really given us the key to unlock the whole project, as well as allow us to surpass our reduction goals.”
