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. -

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. -

Shortridge Date approved: April 18, 2016 ii Abstract The paper industry, which has played a vital social, economic, and cultural role throughout the Wisconsin River valley, has been under pressure in recent decades. Technology has lowered demand for paper and Asian producers are now competing with North American mills. As a result, many mills throughout the valley have been closed or purchased by nonlocal corporations. Such economic disruption is not new to this region. Indeed, paper manufacture itself emerged when local businessmen diversified their investments following the decline of the timber industry. New technology in the late nineteenth century enabled paper to be made from wood pulp, rather than rags. The area’s scrub trees, bypassed by earlier loggers, produced quality pulp, and the river provided a reliable power source for new factories. By the early decades of the twentieth century, a chain of paper mills dotted the banks of the Wisconsin River. -

Abstract Many manuscripts and historical books contain a form of deterioration known as foxing or fox spots, a brownish stain which has the effect of altering aesthetic and visual appeal. The aim of this work is to study the role of the extracts of Water Cantaloupe (CE) and Water melon (WE) separately as natural products in removing foxing spots in various modern and old papers. Old papers and three types of modern papers made from cotton, linen and a mixture of cotton, linen and wood (1:1:1) were used for this purpose. Each type was divided into two groups, one of them was infected with foxing and the other was left as control (uninfected). Infected papers were treated with CE, WE and 2% sodium hypochlorite (as a traditional chemical bleaching) separately. Fourier Transform Infrared Spectroscopy (FTIR), Atomic Absorption Spectroscopy, Scanning Electron Microscopy equipped with Energy-Dispersive X-ray spectroscopy (SEM-EDX) in addition to some optical and mechanical properties were carried out to evaluate the Cantaloupe Extracts (CE) and Water Melon Extracts (WE) use in removing foxing stains compared to sodium hypochlorite. The results showed that CE removed foxing in different studied papers at pH = 7.4.
