A Vancouver-based consortium is proposing a $10-billion refinery for Canada’s West Coast, the second such plan aimed at winning support for processing and exporting petroleum products manufactured from the bitumen in Alberta’s oil sands.

A group called Pacific Future Energy wants to build a massive plant that could eventually process one million barrels a day, constructed in 200,000-barrel-a-day modules. The $10-billion price tag would cover just the first phase, which could be located in Kitimat, B.C., although proponents prefer Prince Rupert, to the north.
