Mills run continuously under high temperatures, extreme pressures, corrosive chemicals, and abrasive slurries. We build the evaporators, exchangers, vessels and tanks that carry that duty.
Harris Thermal has a long history of fabricating heat-transfer and process equipment for the pulp and paper industry. That experience remains valuable for mills maintaining, repairing, or replacing aging equipment as well as for new capital projects.
Harris Thermal fabricates evaporator and heat-transfer equipment used in black-liquor concentration and chemical-recovery applications.
The stream gets more viscous, more scaling and more corrosive as it concentrates, so the material and the evaporator configuration follow where in the train the equipment sits. Our article on choosing an industrial evaporator works through that decision.
Yes, and it is a large part of the pulp and paper work. Replacement heat exchangers built to existing envelope and nozzle geometry, replacement tube bundles for sound shells, vessels, and evaporator components built around the interfaces already in the mill. We work from existing drawings, field measurements or reverse-engineered specifications.
Black-liquor evaporators, falling-film and multi-effect evaporator equipment, condensers, shell-and-tube heat exchangers, replacement bundles, digesters, ASME pressure vessels, columns and towers, cyclones, washer vessels, and mixing vessels and tanks.
Harris Thermal fabricates evaporator and heat-transfer equipment used in black-liquor concentration and chemical-recovery applications, along with the condensers, exchangers and vessels that run with them. Black liquor is a scaling, corrosive, increasingly viscous stream, so material selection and evaporator configuration follow where in the concentration train the equipment sits.
