Pulping and Bleaching Studies
Contact: Sabrina Burkhardt
[email protected]
604.529.2804
Sample Preparation
Whole logs, woodchips and non-wood samples can be processed. Whole logs are used in specific
species studies. Logs are manually debarked and chipped in our disk chipper. Pure species chips
can be evaluated or mixed in specified proportions to produce a new mill chip blend for evaluation.
Mill chip samples or lab produced chips can be further modified using thickness or roundhole chip
screening to determine the impact of chip screening improvements on pulping operations.
Wood and Chip Testing
Chip samples can be classified using thickness or roundhole
screens. Tyler sieve classifiers are available for sawdust
samples. Chip or sawdust samples can also be analyzed for
bark or rot content. The basic wood density of the samples can
be determined or the bulk chip packing density can also be
measured.
Lab Pulping
Kraft cooks can be performed in 6-L bomb digesters or in a 20-L
circulating liquor digester. Bomb cooks are used to evaluate
benefits of anthraquinone, surfactants and deresinating agents.
Because of the small volume (6-L) in our bomb digesters,
overthick chips and chip fines are removed from the chips to
reduce variability in pulping results. One bomb digester cook
produces sufficient pulp for an unbleached strength evaluation.
Bomb cooks are also used to evaluate sawdust samples.
The 20-L circulating liquor digester can cook up to 3000 grams
O.D. for accurate yield determinations. Multiple furnishes can be
evaluated in using the same pulping conditions for layered
cooks. The 20-L digester produces enough pulp for unbleached
and bleached pulp evaluations. We report total yield, screened
yield, rejects, knots and residual EA for all cooks.

Pulping and Bleaching Studies
Contact: Sabrina Burkhardt
[email protected]
604.529.2804
Lab Pulping (continued)
Many pulping processes are simulated in our 20-L digester including kraft, kraft/AQ, sulfite (acid and
alkaline), NSSC medium, kraft liner and chemical pulping. A laboratory refiner is used in the
linerboard and medium studies. Low energy batch simulations, (i.e. RDH®, SuperBatch®) and alkali
profiling cooks can be run (i.e. MCC, EMCC, LoSolids cooks). Pre-hydrolysis by steam, water, or
acid can also be run.
Two atmospheric refiners are available for running mechanical pulping studies or determining chip
brightness after refining.
Bleaching
Bleaching is performed in polyethylene bags or in pressurized reactors. We can simulate any
bleaching process using chlorine dioxide, oxygen, ozone, hydrosulfite, peroxide, hypochlorite or
chlorine. Most of our studies involve the ODEopDED or DEopDED sequences. Enzyme or xylanase
pretreatment can be studied in our laboratory to determine chlorine dioxide savings. Our equipment
is scaled to use 300 g of brown stock, which provides sufficient fully bleached pulp for pulp strength
testing. We can generate 5 to 10 kg of fully bleached pulp for our customer evaluations.

Contaminant Identification
General microscopic examinations identify common pulp and
paper contaminants like shives, bark, sclereids and foreign
material like plastic or synthetic fibers. Chemical identification is
further available by FTIR techniques. Photomicrographs are
often a useful addition.
Photomicrographs
A digital camera specially mounted onto microscopes with 10X through 400X magnification allows
for detailed photographs of your sample. Very helpful in demonstrating what has been observed at
the microscopic level. Many applications including general pulp or fiber qualities, embedded
contaminants, physical materials or debris, general print quality, etc.
Particle Size by Microscopic Methodology
Projecting a high-magnification microscopic image of your solid or liquid sample onto a video
monitor allows for the measurement of particle diameters into any size categories you choose.
Detection limit is 1µm.

Viscose Preparation and Evaluation
Laboratory scale preparation of alkali cellulose is followed by aging to a specified end point target
viscosity. Xanthation of the alkali cellulose results in the formation of cellulose xanthate or viscose.
The viscose is dissolved in alkali with further aging resulting in a viscose solution simulating that
used in the production of rayon. Both the slurry and sheet steeping procedures may be used.
Characterization of viscose preparation and solution includes:
Aging time
Filterability
Haze
Clarity
Ball fall viscosity
In addition, should sheet steeping be assessed, the procedures used allow for the determination of
capillary rise, sheet flotation, caustic absorption, swelling volume and density.
Cellulose Acetate Preparation and Evaluation
Laboratory scale preparation of cellulose triacetate is carried out by the catalyzed acetylation of
conditioned cellulose. This is subsequently hydrolyzed to form secondary cellulose acetate. The
secondary acetate is dissolved allowing for the determination of:
Clogging constant
Plugging value
Haze
Colour
Viscosity
In addition, phase contrast microscopy can be used to photograph the product and to determine the
population of un-acetylated or partially acetylated fibers and the presence of particulate impurities.
Chemical properties such as the Acetyl value may also be determined.
