Avhandlingen försvaras på svenska. © Katarina Karlström Stockholm 2009 Department of Fibre and Polymer Technology Teknikringen 56-58 SE-100 44 Stockholm Sweden Abstract Converting wood into paper is a complex process involving many different stages, one of which is pulping. Pulping involves liberating the wood fibres from each other, which can be done either chemically or mechanically. This thesis focuses on the most common chemical pulping method, the kraft cooking process, and especially on a recently developed improvement of the impregnation phase, which is the first part of a kraft cook. Extended impregnation kraft cooking (EIC) technique is demonstrated to be an improvement of the kraft pulping process and provides a way to utilize softwood to a higher degree, at higher pulp yield. We demonstrate that it is possible to produce softwood ( Picea abies ) kraft pulp using a new cooking technique, resulting in a pulp that can be defibrated without inline refining at as high lignin content as 8% on wood, measured as kappa numbers above 90. -

In this article, a comprehensive review in the area of modeling, control and diagnostics of continuous pulp digesters is conducted. The evolution of research focus within these areas is followed and discussed. Particular effort has been devoted to identifying the state-of-the-art and the research gap in a summarized way. Finally, the current and future research directions in the areas have been analyzed and discussed. To date, digester modeling following the Purdue approach, Kappa number control using model predictive controllers and health index-based diagnostic approaches by utilizing different statistical methods have dominated the field. While the rising research interest within the field is evident, we anticipate further developments in advanced sensors and integration of these sensors for improving model prediction and controller performance; and the exploration of different AI-based approaches will be at the core of future research. Keywords: Kraft pulping; pulp digester; modeling; control; diagnostics 1. Introduction With the widespread expansion of the Internet, electronic media and paperless communication, the demand for the graphic paper (i.e., newsprint and higher-value printing and writing paper) has been declining since 2000 [1]. -

Tech students Maharanapratap College of Technology, Gwalior, [email protected] [email protected] [email protected] ABSTRACT Corrugated board is widely used in the packing industry. The main advantages are lightness, recyclability and low cost. This makes the material the best choice to produce containers devoted to the shipping of goods. Furthermore examples of structure design based on corrugated boards can be found in different fields. Structural analysis of paperboard components is a crucial topic in the design of containers. It is required to investigate their strength properties because they have to protect the goods contained from lateral crushing and compression loads due to stacking. However in this paper complete and detailed information are presented. Keywords: - corrugated boards, recyclability, compression loads. Smaller flutes offer printability advantages as well as I.

Corrugated 101! ! !Corrugated Vs
Corrugated 101! ! !Corrugated vs. Cardboard! • The term "cardboard box" is commonly misused when referring to a corrugated box. The correct technical term is "corrugated fiberboard carton.”! • Cardboard boxes are really chipboard boxes, and used primarily for packaging lightweight products, such as cereal or board games.! • Corrugated fiberboard boxes are widely utilized in retail packaging, shipping cartons, product displays and many other applications ! requiring lightweight, but sturdy materials.! !Corrugated Composition! Corrugated fiberboard is comprised of linerboard and heavy paper medium. Linerboard is the flat, outer surface that adheres to the medium. The medium is the wavy, fluted paper between the liners. Both are made of a special kind of heavy paper called !containerboard. Board strength will vary depending on the various linerboard and medium combinations.! • Single Face: Medium glued to 1 linerboard; flutes exposed! • Single Wall: Medium between 2 liners! • Double Wall: Varying mediums layered between 3 liners! !• Triple Wall: Varying mediums layered between 4 liners! !Flute Facts! !Corrugated board can be created with several different flute profiles. The five most common flute profiles are:! • A-Flute: Original corrugated flute design. Contains about 33 flutes per foot.! • B-Flute: Developed primarily for packaging canned goods.

Importance of Unbleached Pulp Lignin Content
ENVIRONMENTAL FOOTPRINT COMPARISON TOOL A tool for understanding environmental decisions related to the pulp and paper industry EFFECTS OF DECREASED RELEASE OF CHLORINATED COMPOUNDS ON ENERGY USE Importance of Unbleached Pulp Lignin Content Kappa number is a measure of the amount of lignin remaining in pulp. The higher the kappa number value, the higher the use of bleaching chemicals required to brighten the pulp. The kappa numbers of pulps leaving the digester are typically about 30 for softwoods and 20 for hardwoods in bleached kraft mills that employ conventional cooking methods. Several modifications to conventional cooking, known collectively as extended cooking (EC), have enabled kappa numbers to be further reduced in the digester in ways that minimize yield and strength losses. Kappa numbers associated with EC are about 20 for softwoods and about 14 for hardwoods. Oxygen delignification (OD) is another technology that is used extensively to lower the residual lignin content prior to the bleach plant. The technology is more selective than most extended cooking processes. Lignin reductions of approximately 50% are achievable with OD, resulting in softwood kappa number in the 14-18 range. Some mills use both extended cooking and oxygen delignification to achieve very low kappa number pulps prior to bleaching, producing pulps with kappa number values in the range of 10-12, perhaps even lower. Deterioration of pulp strength properties is the limiting obstacle for kappa number reduction prior to the bleach plant. More recent strategies have been focused away from obtaining the most delignification possible in the digester and toward optimizing the fiberline as a whole based on economic, quality, and environmental factors. -

Conservation of Coated and Specialty Papers
RELACT HISTORY, TECHNOLOGY, AND TREATMENT OF SPECIALTY PAPERS FOUND IN ARCHIVES, LIBRARIES AND MUSEUMS: TRACING AND PIGMENT-COATED PAPERS By Dianne van der Reyden (Revised from the following publications: Pigment-coated papers I & II: history and technology / van der Reyden, Dianne; Mosier, Erika; Baker, Mary , In: Triennial meeting (10th), Washington, DC, 22-27 August 1993: preprints / Paris: ICOM , 1993, and Effects of aging and solvent treatments on some properties of contemporary tracing papers / van der Reyden, Dianne; Hofmann, Christa; Baker, Mary, In: Journal of the American Institute for Conservation, 1993) ABSTRACT Museums, libraries, and archives contain large collections of pigment-coated and tracing papers. These papers are produced by specially formulated compositions and manufacturing procedures that make them particularly vulnerable to damage as well as reactive to solvents used in conservation treatments. In order to evaluate the effects of solvents on such papers, several research projects were designed to consider the variables of paper composition, properties, and aging, as well as type of solvent and technique of solvent application. This paper summarizes findings for materials characterization, degradative effects of aging, and some effects of solvents used for stain reduction, and humidification and flattening, of pigment-coated and modern tracing papers. Pigment-coated papers have been used, virtually since the beginning of papermaking history, for their special properties of gloss and brightness. These properties, however, may render coated papers more susceptible to certain types of damage (surface marring, embedded grime, and stains) and more reactive to certain conservation treatments. Several research projects have been undertaken to characterize paper coating compositions (by SEM/EDS and FTIR) and appearance properties (by SEM imaging of surface structure and quantitative measurements of color and gloss) in order to evaluate changes that might occur following application of solvents used in conservation treatments. -
