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. -
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. -
Odorless Pulp Mill in Operation
Published May 26, 2017 Odorless Pulp Mill Odorless pulp mill in successful operation Executive Summary The sulphur in the cooking process can result in bad odor in the surroundings of a Kraft pulp mill. Together with the odor, sulphur compounds can also be an environmental problem since they are released to the atmosphere. Although emissions are becoming lower as mills are upgraded, odors have continued to be a problem for people living close to the mills, because of the very low odor threshold of sulphur compounds. Valmet has delivered a unique, practically odorless mill to CMPC Riograndese Ltda in Guaíba, Brazil. The design guidelines were to not vent odorous gases and to aim for zero smells. The gas handling system collects and controls odors from more than 100 sources and all process areas are included. Incineration of non-condensable gases is ensured through multiple, simultaneously available incineration locations. According to CMPC it can be said that the system availability is practically 100% and there is always a system ready to handle NCG and prevent gases from being emitted to the atmosphere. This paper describes the emphasis CMPC placed in the concept of the odorless mill in Guaíba and its surroundings and outlines the chosen technical solutions to achieve this target. The paper emphasizes the necessity of ensuring that odorous gases are treated also in shutdown and emergency situations, and explains how this has been achieved at the mill. © Valmet Page | 1 Published May 26, 2017 Odorless Pulp Mill Background No venting of odorous gases and a "zero smell" pulp mill. -

PULP AND PAPER MILLS 33 PULP AND PAPER MILLS The two common forms of chemical pulping are 1) the dominant “alkaline” or “kraft” process, and Processes 2) the “acid pulping” or “sulphite” process.

Systematic Review on Isolation Processes for Technical Lignin
processes Review Systematic Review on Isolation Processes for Technical Lignin Marlene Kienberger *, Silvia Maitz, Thomas Pichler and Paul Demmelmayer Institute of Chemical Engineering and Environmental Technology, Graz University of Technology, Inffeldgasse 25c, A-8010 Graz, Austria; [email protected] (S.M.); [email protected] (T.P.); [email protected] (P.D.) * Correspondence: [email protected]; Tel.: +43-031-6873-7484 Abstract: Technologies for the isolation of lignin from pulping process streams are reviewed in this article. Based on published data, the WestVaco process, the LignoBoost process, the LigoForce SystemTM and the SLRP process are reviewed and discussed for the isolation of lignin from Kraft black liquor. The three new processes that have now joined the WestVaco process are compared from the perspective of product quality. Further, isolation processes of lignosulfonates from spent sulfite liquor are reviewed. The limitation for this review is that data are only available from lab scale and pilot scale experiments and not from industrial processes. Key output of this paper is a technology summary of the state of the art processes for technical lignins, showing the pros and cons of each process.
