  • Basics of Kraft Pulping
    Lignin Wood is composed of many chemical components, primarily extractives, carbohydrates, and lignin, which are distributed nonuniformly as the result of anatomical structure. Lignin is derived from the Latin term lignum, which means wood.1 Anselme Payen (1838) was the first to recognize the composite nature of wood and referred to a carbon- rich substance as the “encrusting material” which embedded cellulose in the wood. Schulze (1865) later defined this encrusting material as lignin. Lignin has been described as a random, three-dimensional network polymer comprised of variously linked phenylpropane units.2 Lignin is the second most abundant biological material on the planet, exceeded only by cellulose and hemicellulose, and comprises 15-25% of the dry weight of woody plants. This macromolecule plays a vital role in providing mechanical support to bind plant fibers together. Lignin also decreases the permeation of water through the cell walls of the xylem, thereby playing an intricate role in the transport of water and nutrients. Finally, lignin plays an important function in a plant’s natural defense against degradation by impeding penetration of destructive enzymes through the cell wall. Although lignin is necessary to trees, it is undesirable in most chemical papermaking fibers and is removed by pulping and bleaching processes. 1.1.1 Biosynthesis Plant lignins can be broadly divided into three classes: softwood (gymnosperm), hardwood (angiosperm) and grass or annual plant (graminaceous) lignin.3 Three different phenylpropane units, or monolignols, are responsible for lignin biosynthesis.4 Guaiacyl lignin is composed principally of coniferyl alcohol units, while guaiacyl-syringyl lignin contains monomeric units from coniferyl and sinapyl alcohol.

Washington, DC 20460 Re: Reguest for Full Exemption of Four Pulping Chemicals from the TSCA Chemical Data Reporting Rule Reguirements Dear Administrator McCarthy: The American Forest & Paper Association (AF&PA) hereby petitions EPA to amend the Chemical Data Reporting rule (CDR), 40 C.F.R. Part 711, to exempt from all CDR requirements four pulping chemicals involved in the manufacture of paper and other pulp-based products. The four pulping chemicals are complex mixtures used in the kraft pulping process: • Sulfite Liquors and Cooking Liquors, white (CAS No. 68131-33-9) (white liquor) • Sulfite Liquors and Cooking Liquors, spent (CAS No. 66071-92-9) (black liquor) • Sulfite Liquors and Cooking Liquors, spent, oxidized (CAS No. 68514-09-0) (black liquor, oxidized) • Sulfite Liquors and Cooking Liquors, green (CAS No. 68131-30-6) (green liquor) Each of these substances is manufactured and recycled onsite in a continuous closed loop. EPA has an enormous amount of information about these pulping chemicals and little current interest in them, as their potential risks are well understood and adequately managed. 1101 K Street, N.W., Suite 700 • Was hington, D.C.20005 • (202) 463•2700 •afandpa.org May 6, 2015 Page 2 This petition first identifies the four pulping chemicals in greater detail and explains why the kraft chemical regeneration process has led to inflated production volumes for these pulping chemicals in CDR data.

  • A Dynamic Na/S Balance of a Kraft Pulp Mill
    A dynamic Na/S balance of a kraft pulp mill Modeling and simulation of a kraft pulp mill using WinGEMS En dynamisk Na/S balans av ett sulfatbruk Modellering och simulering av ett sulfatbruk i WinGEMS Per Andersson Faculty of Health, Science and Technology Department of Engineering and Chemical Science, Chemical Engineering, Karlstad University Master theisis, 30 credits Supervisors: Niklas Kvarnström (KAU), Maria Björk (Stora Enso), Rickard Wadsborn (Stora Enso) Examinat or: Lars Järnström (KAU) 2014 -01-08 Version : 2.0 Abstract The main scope of this thesis was to create a simulation model of a kraft pulp mill and produce a dynamic Na/S balance. The model was made in WinGEMS 5.3 and the method consisted of implementing a static Na/S balance from the mill and created a model that described this chemical balance. Input data from the mill was collected and implemented in the model. A number of different cases were simulated to predict the effects of different process changes over time, dynamic balances. The result from the static balance showed that the model can describes the mill case. The result from the dynamic simulation showed that the model can be used to predict the effect of process changes over shorter periods of time. Executive Summary In the kraft mill the chemical balance is of interest to minimize the production cost. Normally there is an excess of sulfur and low levels of sodium, compared to what the process requires. In the future, the pulp mill will most likely produce other products than just pulp. These new production processes will also most likely affect the sodium and sulfur balance and there is a need to be able to predict this change.

  • Flow Sheet Pulp and Paper Green Liquor / White Liquor Circuit
    WesTech’s Continuous Rotary Drum Filters provide a wide range of liquid-solids separation for many types of industrial processing flow sheets. They offer the operating flexibility to handle dewatering, washing, and filtration applications. Working with the customer, WesTech provides laboratory test data to assess process optimization, design, and sizing of the equipment supplied. WesTech Drum Filters are available up to 13.5 feet in diameter and 36 feet in length and are built for ease of operation as well as to meet demanding customer specifications. Pulp and Paper Dregs The most common process for making paper is called The dregs from the green liquor clarifier are sent to the Kraft or Kraft Mill process. In this process, wood a rotary vacuum filter called the “dregs filter.” Here chips are “cooked” at 150 - 165o C, under pressure the dregs are washed to remove residual chemicals in a liquid solution containing caustic (NaOH) and and are dewatered prior to disposal. The liquids are sodium sulphide (Na2S) to pulp the wood. recycled to the green liquor stabilization tank.

  • Resin Profile in a Bleached Kraft Pulp Process
    Resin Profile in a Bleached Kraft Pulp Process Jennie Berglund May 2012 Degree Project in Polymeric Materials, First Level Department of Fibre and Polymer Technology Royal Institute of Technology Stockholm, Sweden Abstract The aim with this project was to investigate how the amount and composition of resins varied during the process producing bleached birch pulp at the mill SCA Packaging Munksund. A literature study about how the resin removal can be improved has also been included. Problems with resins in the process are common at pulp and paper mills, especially when birch is used as a raw material. The resin can cause deposits on the equipment leading to process stops, but also lowered mechanical properties and spots on the paper products. The addition of tall oil to the digester is one way of improving the removal of resins, seasoning of wood, and a good debarking are other ones. Also the different washing and bleaching steps can affect the amount of resin remaining in the pulp. In this study pulp samples from eight different positions in the process were analyzed. To extract the samples a Soxtec device was used. Results showed that the most effective resin removal happened during the washing in their first washing step after the digester, a DD-washer. Here 77 % of the resin was removed, of totally 88 % during the whole process. Another step which was effective was the final washing step, the PO-press. About 36 % of the remaining resins in the pulp which entered the PO-press were washed out here. The extracts were analyzed with GC-FID and GC-MS to identify and quantify the substances, and determine how the composition varied over the manufacturing process.

  • GPI West Monroe Digester Optimization Project Valmet Inc
    Kari Lampela, Solution Manager, Valmet Danny Zuver, APC Engineer, Valmet Dennis Carwile, Sr. Manager-Manufacturing Services/Pulp Leader, Graphic Packaging GPI West Monroe digester optimization project Valmet Inc. and Graphic Packaging Intl. (GPI) collaborated on continuous digester optimization projects that included three digesters in West Monroe, Louisiana. Graphic Packaging is one of the world’s largest manufacturers of folding cartons, unbleached paperboard, coated recycled board, microwave packaging and machinery. The West Monroe facility manufactures combined folding carton for use in beverage and other product packaging. Kraft pulp digester operation plays a critical role in the whole pulp mill economy. Furthermore, high and steady pulp quality results in additional bottom line profits for the paper mill. The key to pulp production and quality optimization is to ensure selective delignification, which can be accomplished by precise and strategic management and control of optimum cooking conditions. Accurate and reliable pulp quality measurements are essential elements of an advanced control package. Continuous cooking alkali profile management has become an increasingly important factor to maintain quality targets. Information about the cooking liquor composition within the process can be utilized to determine the alkali profile in the digester and to optimize the addition of cooking chemicals into the process. Cooking liquor measurements give indirect information about the extent of the cooking degree. Typical variation of the white liquor strength is generally 5 %, or greater after production breaks. If this variation is not measured and controlled, it will have a significant effect on cooking conditions and pulp quality. Kappa and residual alkali measurements provide an accurate estimate of pulp yield and with enhanced control of delignification and alkali profile, the mill can increase pulp yield while maintaining steady blow Kappa level.

  • Crude Tall Oil Low ILUC Risk Assessment Comparing Global Supply and Demand
    Crude tall oil low ILUC risk assessment Comparing global supply and demand Crude tall oil low ILUC risk assessment Comparing global supply and demand By: Daan Peters, Viktorija Stojcheva Date: 24 April 2017 Project number: SISNL17494 © Ecofys 2017 by order of: UPM ECOFYS Netherlands B.V. | Kanaalweg 15G | 3526 KL Utrecht| T +31 (0)30 662-3300 | F +31 (0)30 662-3301 | E [email protected] | I www.ecofys.com Chamber of Commerce 30161191 Executive Summary UPM produces renewable diesel and naphtha from crude tall oil (CTO) in its biorefinery in Lappeenranta, Finland from early 2015 onwards. Because the company wanted clarity on the status and sustainability of its feedstock, UPM asked Ecofys in 2013 to assess whether CTO can be regarded as a residue and whether the feedstock would be low ILUC risk, meaning its use for biofuels would not lead to displace- ment effects of existing other uses. The current report is an updated version of the 2013 report. An important change since the previous report is that biofuel production at UPM has started, so any effects of CTO usage for biofuels has on the CTO market would be visible. Ecofys studies the following questions in this report: 1. Can CTO be defined as a residue based on biofuel legislation 2. Does the feedstock create an additional demand for land (is it a low ILUC risk feed stock?) 3. Does the use of the feedstock for biofuel production cause significant distortive effects on markets? The second and third question are closely interlinked. CTO in itself is a non-land using feedstock.
