Tissue360 - Spring/Summer 2018 - 40

Tissue making at the La Riba mill has been going strong since 1950. Recycled fiber helps GomàCamps differentiate its value-added products like napkins, tablecloths, and specialties.

Intern Ander Arregui Biera and Jordi Gomà-Camps Travé proudly show the "clear" performance of their
wastewater facility. Water is returned to the Brugent river at a high level of cleanliness Water usage per
tonne of tissue is as little as four to five liters, and no more than seven liters for recycled grades.

Then Kadant added a complementary device
to boost performance even higher. In addition
to fiber loss savings, now energy costs dropped
and fiber quality increased. We now have two
Boostek™ units, which paid for themselves
in less than six months. They run non-stop
without any need for attention."
According to Stephan Pottier, product R&D
manager, Kadant Lamort, "Gomà-Camps is
ideal as a pioneering partner for optimizing industrial performance. Some years ago
they switched from five screens to just one.
That was a leap of faith for management and
production. The same is true for their recent
advances in deinking and cleaning. Mutual
trust and frequent exchange of ideas are the
basis for success of the Boostek invention."

ACHIEVING FIBER AND ENERGY GAINS
Kadant's latest screen performance enhancer,
known as the Boostek performance pack,
goes beyond the traditional boundaries for
pressure screens.  Typically, a boost in fiber
yield occurs, while reducing stickies and
energy consumption.  
The Boostek technology utilizes system
pressure to amplify the breakdown of stock
mats that form on, and ultimately block, the
screen cylinder. At Gomà-Camps, the unit is
connected to the third accept of the ScreenOne
three-stage fine screening system, where
cleaning occurs. There is never a need to clean
with the rotor. A lower rotor speed results in
less energy consumption, while the quality of
the accepts is also improved.

A secondary, smaller Boostek performance
pack is connected to the reject line, which creates another macro-pulsation. Working with a
small flow on the reject line means less fiber loss.
Says Gomà-Camps Travé, "Boostek is so
simple that it just works without any need for
attention. There are no negative effects on the
process. Payback has happened much sooner
than we had anticipated."
Pau Valencia, deinking line leader, says that
the stock preparation Boostek units work well,
in part because they reduce the speed of the
reject lines. "There are only three positions that
matter. The first one blocks the inlet flow. The
second one runs all the time, blocking nothing.
The third position blocks the outlet."
Gomà-Camps Travé notes that much of the
confidence in Boostek technology came from
its successful conversion of five screens to one
screen back in 2009. "Quality increased and
capacity doubled. Stickies were no longer an
issue. Power consumption was reduced by 250
kW. Adding to this, the Boostek system recently
gave us another savings of 100 kW with more
quality gains, too."
Comments Marga Biera, sales & technical
support for Kadant in Iberia, "Gomà-Camps
plays an important role in tissuemaking
because of their flexibility to try new solutions.
They are willing to take calculated risks. Now,
the Boostek technology is fully commercialized
and has been proven at a dozen other mills. It's
even available on a skid for rent."
POTENTIAL BENEFITS OF THE
BOOSTEK PERFORMANCE PACK
* Capacity increase up to 25 percent
* Energy savings up to 50 percent
* Reduction of fiber losses up to 65 percent
* Reduction of rejects up to 50 percent in weight
* Low installation cost and rapid payback
Valencia notes that a major challenge is dealing with a wide range in raw material quality.
"We have achieved flexibility to make fast production changes because of many small upgrades
over the years, and many of those from Kadant."
PRECIOUS WATER
Water is more frequently reused throughout the
mill. A fundamental change was the installation
of a membrane bioreactor in the biological water
treatment plant back in 2011. Gomà-Camps
Travé notes that using only five to seven liters
of water per tonne of tissue paper puts the mill
in the forefront. "Our goal is to protect water in
this scenic, arid part of Spain. Sustainability is
part of our nature."
