white liquor production. The most recent
white liquor plant installations have been
predominantly in Brazil. These installations
are often large single line processes with lime
kilns producing greater than 1000 metric tpd
of lime.
Approximately 100 people attended the
event, with a one-third split between mill
personnel, suppliers, and others. This meant
superb opportunities for learning on a wide
range of lime kiln-related topics. My own
presentation was well-received, and I heard
plenty of ideas from participants related to our
kiln ringing issues. The meeting organizers
and TAPPI staff were excellent hosts, making
me feel extremely welcome.

One of the most rewarding and enjoyable parts of my career in the pulp and paper
industry has been the opportunity to investigate and solve problems. The problem-solving process means that you are discovering,
adapting, and generating new information
to address the problem at hand. In simple
terms, you are acquiring knowledge in the
pursuit of a solution. However, sometimes
this problem-solving process does not find
a solution easily.
This has been the case for a persistent lime
kiln ringing problem at Australian Paper's
Maryvale mill. In fact, problem-solving of this
issue has not reached a successful conclusion
after several years of investigations.
Problem-solving can be a solitary task,
but in my experience it is best approached
by taking input from more minds than just my
own. Relevant information may be available
in textbooks, seminars, published papers, or
on the web; however, when it comes to complex mill issues-like kiln ringing-nothing
beats face-to-face discussions and the ability
to actually observe in person. The issue for us
Down Under is that the critical mass of pulp
and paper mills, and therefore the majority
of knowledge, is nowhere near us-it's locked
up on the other side of the world.

JULY/AUGUST 2017

Fortunately, in June 2016 I was able to
bridge that gap and meet my need for information and experience on this difficult and
persistent problem. I attended and presented
at TAPPI KilnCon 2016, and then visited the
Daishowa Marubeni International (DMI)
Peace River mill in Alberta, Canada. Partial
funding for the trip came from prize money
I had won during the Best Mill Paper awards
at the annual Appita conference (Appita
is the Australian pulp and paper industry
technical association.)
FIRST STOP: KILNCON
KilnCon 2016 was held in Destin, FL,
and was hosted by TAPPI's Gulf Coast and
Southeastern Local Sections. This annual
meeting has found a niche where the focus
is solely on lime kiln operations in the pulp
and paper industry. It was an ideal event in
my quest for extra knowledge and experience
related to lime kilns, and specifically about
kiln ringing. The event included three technical seminars and a full-day technical conference where I was privileged to be a presenter.
Major suppliers such as Valmet and Andritz
made presentations on the latest technology,
including their offerings of external mud
dryers, coolers, burners, and equipment for

STOP 2: DMI PEACE RIVER
The next stop on the trip was the DMI
Peace River mill. Getting to the mill was a
long journey from Florida, but well worth
it. This mill is a purpose-built, single line
market pulp mill producing both hardwood
and softwood bleached market pulp. Built in
1990, the mill is virtually enclosed inside due
to the cold weather conditions in this part
of Canada. The mill is 50 percent owned by
Nippon Paper Industries (NPI), the owner of
Australian Paper, which meant that gaining
access for my visit was straightforward.
I was able to spend a whole day discussing
and observing the Peace River operations-in
particular, their lime kiln. They operate a
kiln of size and design very similar to that at
Maryvale. They, too, have had ringing issues
in the past, so my need for practical knowledge
and experience with ringing was well-supplied. Many thanks to my hosts Joe Fawcett,
power and recovery manager; and Moise Dion,
power and recovery process specialist.
KilnCon and the Peace River mill visit were
invaluable in terms of helping our problemsolving process for kiln ringing. In addition,
the trip provided context and understanding
about how other people manage this issue.
Several ideas will be added to our investigations as a result of this trip, including how we
handle purchased lime, avoiding intermittent sump pump surges in lime mud washer
