Operational Data Helps
Mills Meet Challenges
MARIANA SANDIN

In a digital world, the paper industry
has been forced to reinvent itself to remain
relevant. However, that reinvention means
mills must get more creative. That ingenuity is breathing hope into the industry: many
mills are thriving because they're optimizing operations to improve profit margins, or
even reinventing uses for wood to meet new
demands. With no precedent or subject matter
experts to help them navigate these changes,
they're turning to insights from real-time
operational data.
It's more important than ever for mills to
continue to produce a high-quality product as
quickly and efficiently as possible. Equipment,
energy, and mill operator proficiency all
contribute to the bottom line, and there are
multiple potential points of failure in this
complex network of machinery, employees,
and equipment. Even small changes in equipment functionality can indicate that a catastrophic failure is imminent, or a slight tweak
in a seemingly innocuous setting can increase
energy use or result in a poor-quality product.
We'll look at the different approaches four
mills have taken to using real-time data.
CONVERTING A MILL:
FORTRESS SPECIALTY CELLULOSE
For some mills, uncovering new business
opportunities has proven to be more effective
than optimizing existing production methods.
Fortress Specialty Cellulose's mill in Thurso,
Quebec, opted to convert its equipment to produce dissolving pulp. Converting an entire
mill is an expensive, labor-intensive process
and, given the efforts, puts the mill at financial risk; yet, when done correctly, it can have
long-term benefits.
The original mill had closed in 2009, but
was purchased by Fortress in 2010. In 2011,
Fortress embarked on a complex and ambitious journey: Rather than remaining a standard kraft pulp production mill, Fortress opted
to convert the mill to a dissolving pulp production facility. Dissolving pulp is manufactured

Fortress was experiencing as many as 100 water hammer incidents per day; daily notifications helped
reduce incidents by 97 percent.

The PI System helped Fortress reduce the number of mill shutdowns.

in the mill and is then sent to textile customers
where it is converted to rayon.
Producing pulp that can be successfully
converted to rayon requires a different level of
quality than the traditional paper approach.

NOVEMBER/DECEMBER 2017

Paper grade quality is determined by strength
and optical properties; in textiles, quality is
measured by viscosity, purity, and reactivity.
For dissolving pulp, it is imperative that the
lignin and the cellulose be separated during
