Harmac Pacific operates a Northern Bleached Softwood Kraft (NBSK) pulp mill located on the east coast of Vancouver Island near Nanaimo, British Columbia.
Allnorth provided detailed engineering services for the upgrade of the no. 1 pulp machine fourdrinier table. New Uhle boxes were also installed on the first, second and third presses. As part of the Grade 20 CCE design work, Allnorth completed a vacuum system audit to determine if the existing system had the capacity to support the new fourdrinier table equipment. The four existing vacuum pumps were replaced with three new ones and there were numerous piping changes. The vacuum audit determined the couch low vacuum zone was not required for normal operation.
The use of laser point cloud scanning of the existing area enabled the design of new piping and equipment in a very congested area without piping or equipment interference.
