HOUSTON, Sept. 5 -- Syncrude Canada Ltd. has introduced bitumen feed into Coker 8-3 at its Mildred Lake oil sands plant in Alberta in a phased-restart of Stage 3 operations.
Canadian Oil Sands Trust, a partner, said production would increase in phases to allow for testing of a flue gas desulfurization (FGD) unit that had to be shut down because of odorous emissions during start-up in May (OGJ Online, July 10, 2006).
Ammonia produced on site for the FGD unit was found to contain impurities and to be responsible for the odors. Syncrude is now using imported ammonia.
