Norampac mill's black liquor gasification system in full operation

Jan 26, 2007 - A black liquor gasification project at Norampac's Trenton, Ontario mill has achieved a major milestone in transitioning from commissioning to full commercial operation. The mill also recently completed air emissions testing at the facility, as mandated by the Ontario Ministry of Environment.

According to ThermoChem Recovery International (TRI), the company that provided gasification technology to the mill, the Trenton mill is the world's first commercial low temperature black liquor gasification system, and has achieved over 18,000 hours of operation.

"This is an important milestone for the technology and for the Trenton mill," said JJ Davis, general manager of the mill. "We continue to be committed to spent liquor gasification at Trenton and are working with TRI to gain even more steam production and energy savings."

The project at Trenton utilizes TRI's low temperature biomass gasification technology to recover chemicals and energy from the spent pulping liquor the mill produces in the manufacture of corrugating medium, TRI said.

The project meets the total spent liquor requirements of the mill, and supplies cooking liquor and process steam back to the mill to support the pulp and paper making operation, TRI added.
