Viscose Preparation and Evaluation

Laboratory scale preparation of alkalicellulose is followed by aging to aspecified end point target viscosity.Xanthation of the alkali cellulose results in the formation of viscose.The viscose is dissolved in alkali withfurther aging resulting in a viscosesolution simulating that used in theproduction of rayon. Both the slurry andsheet steeping procedures may be used.• Gel Content • Photomicrographs of viscose dope• Salt index

Characterization of viscose preparationand solution includes:• Aging time • Filterability• Haze • Clarity• Ball fall viscosityIn addition, should sheet steeping beassessed, the procedures used allowfor the determination of capillary rise,sheet flotation, caustic absorption,swelling volume and density.

Cellulose Acetate Preparation andEvaluation Laboratory scale preparation of cellulose triacetate is carried out bythe catalyzed acetylation of conditionedcellulose. This is subsequently hydrolyzedto form secondary cellulose acetate.

The secondary acetate is dissolved allowing for the determination of:• Clogging constant• Plugging value• Haze• Colour• Viscosity• Acetyl value

In addition, phase contrast microscopycan be used to photograph the productand to determine the population ofun-acetylated or partially acetylatedfibers and the presence of particulateimpurities.

Fock Reactivity A micro-scale preparation of viscoseusing a 0.5g sample of pulp. Test includes: Pulp sample preparationand conditioning, alkylation/xanthation,followed by cellulose regeneration asa measure of pulp reactivity. All samples are completed in duplicate.

Econotech is experienced in the highly-specialized production and testing of dissolvingpulp grades. Our experience dates back to the founding days of Econotech, when in 1972,we acquired the lab facilities and equipment of Columbia Cellulose, a manufacturer ofdissolving pulp. Our unique skills and facilities enable us to simulate the productionof viscose or acetate grades of pulp and provide detailed information on their properties.

Sample Preparation and Chip Testing:• Disc chipper – Chipping of wood logs or bamboo

• Thickness, roundhole, Tyler sieve classifiers – Chip, sawdust or nonwood size classification

• Rot content, basic wood or bulk chip density

• Centricleaner and pulp screens – cleanup of nonwoods or contaminated pulps, removal of shives

Pulping:• 20-liter circulating liquor digester – simulates continuous or batch kraft, soda-AQ, sulfite (acid

and alkaline), kraft liner, low energy batch simulations (i.e. RDH®, SuperBatch®),

alkali profiling cooks (i.e. MCC, EMCC, LoSolids cooks), and pre-hydrolysis studies using steam,

water, or acid. Uses up to 4000g od sample per cook. Benefits include most reliable yield data,

customizability (additives may be applied during cook, separate layers in digester), and larger

pulp sample typically allows for brown and bleached strength studies.

• 6-liter and 1-liter bomb digesters – simulate batch kraft, soda-AQ, high kappa kraft, and custom

projects. 6-liter bomb uses up to 900g od sample, 1-liter K-bomb up to 120g od sample.

Benefits include multiple cooks completed simultaneously in oil bath (up to three 6-liter bombs,

and six 1-liter bombs), small sample size needed, excellent method for isolating unknown

conditions, and the sealed nature of the bomb digesters allow for very high pressures.

• 12-inch laboratory refiners – Atmospheric refiner with interchangeable plates and patterns,

available for running basic mechanical pulping studies, determining wood brightness from

chips, or breaking apart fiber bundles in high kappa cooks.

Note: All chemical pulping trials include total yield, screened yield, rejects, kappa or K# and residual EA.

How well is your lime kiln performing?To understand how well your lime kiln is working, you need to have a measure of product quality. Residual

carbonate in reburned lime is a primary indicator that can help operators tune their kilns to avoid under- or

overburning. Econotech’s RLA enables operators to regularly test and monitor residual carbonate through the

day, supporting a stable and efficient kiln operation.

Using the reliable RLA data as a critical kiln control parameter, mills have realized significant benefits:• Reduced energy/fuel costs

• Less overburning and underburning

• Stronger, more stable recausticizing operation

• Increased causticizing efficiency

• Improved white liquor quality

Large Sample. Better Results.Our RLA tests 2.00g of lime, making it easier to obtain a representative sample. Large samples also make the

results less sensitive to weighing error and produce more CO2 for better measurement accuracy.

RLA G4: Enhanced DesignEconotech’s RLA was redesigned after extensive customer consultations. The result: a practical new design,

improving on accuracy and robustness.

Improved Accuracy– Percent calcium carbonate is read directly from the RLA’s calibrated burette, which incorporates a validated offset to account for gas expansion due to heating. Consistently adding the same

amount of acid is easier with an innovative design including a simplified auto-pipette and control valve system.

Corrosion Resistant– Almost all metal has been eliminated from the updated design. Glass and polymercomponents also provide excellent corrosion resistance. Its durability gives way to a longer service life and

lower maintenance in harsh mill environments.

26 27

At the mill, every penny counts. In a highly competitive global market where energy and chemical costs are at a premium, you scrutinize every aspect of your operations to reduce costs and gain a competitive edge. The lime kiln is one of those areas. Overburning deactivates lime and wastes energy, while underburning elevates deadload and reduces recaust efficiency, again resulting in waste. Stable production of high qualitylime is key.

Easy to Use– Fewer critical testing steps mean easier operator training to achieve consistent results. The leveling bottle is attached to the stand and can be adjusted and locked into place/unlocked with one hand.

Durable screw-in reaction jars make it much easier to secure and properly seal, reducing errors and jar break-

ages.

Safer – Acid bottles are now completely secure with no loose tubing to catch on. Acid is also contained duringthe reaction, eliminating any concern of spillage.

Compact– RLA’s smaller footprint only requires about one square foot of bench space.

Confirming Correct ResultsEconotech now offers Reburned Lime Reference Material.

Each 2.0-gram sample comes with a Certificate of Analysis.

These samples provide an easy way to confirm that your

RLA is giving you correct results and is a useful tool for

training staff on the consistent operation of the analyzer.

Optimization of lime productionand quality can lower operatingcosts at the mill.

Our RLA tests 2g of lime, makingit easier to get a representativesample.
