The mechanics, factors and prevention of size press orange peel

A common problem on film metering size presses is orange peel. Orange peel is caused when the coating film splits away from the coated sheet in the immobilized coating layer at the exit of the size press nip.

Common ways an OEM partner helps mills achieve their goals

Maintaining a strong relationship with a trusted OEM partner lets producers learn from the industry’s manufacturing legacy and keep operations moving forward.

Reel primary arm synchronization avoids bottom jumbo reel losses

If you suspect that you are losing excessive paper on the bottoms of your jumbo rolls, the primary arms may be the culprit. Primary arm synchronization is critical for the reel to function properly during turn-up situations.

Recovery boiler selective catalytic reduction - a retrofit case

SCR – Selective Catalytic Reduction is a well-established and widely used technology for NOx removal from power boiler flue gases. Target emission levels are decreasing and SCR will soon be needed for recovery boilers. This article is an abstract of a white paper which presents a study for a retrofit case using SCR to lower NOx from 200 to 100 mg/m3 (6% O2, dry gas), including implementation of some high power features.

Six problems in the evaporator stage and possible solutions

Evaporators are used to evaporate black liquor from approximately 15% dry solids to 70-85% dry solids. Operating issues include scaling, corrosion, liquor carry-over, vacuum, condensate segregation and foaming liquor. Each can be mitigated with process and technology changes.
