CONSTRUCTION • PUBLIC WORKS • NATURAL RESOURCES Volume 8, Number 9 • October 2003 Welcome to InfraStructures CONSTRUCTION • TRAVAUX PUBLICS • RESSOURCES NATURELLES Volume 8 Number 9 Until recently, InfraStructures has been read mainly by French speaking October 2003 users of heavy machinery. Over the last seven years, InfraStructures has become a leader in its field. First by becoming the only magazine covering all aspects of the industry published in French in Canada. Then by being the first to publish all its editorial content on the web, and also by being the only construction magazine, published in French, having a significant readership outside the Province of Quebec. ÉDITOR / PUBLISHER Jean-François Villard For many years, we have received requests for an English version of InfraStructures. Technical limitations, and the lack of advertising revenue have prevented us from publishing such a magazine in print. Now, with the ADVERTISING extent of the use of Internet by professionals, we feel that the time as come MONTRÉAL for a portable digital file (.pdf) version of InfraStructures in English. Jean-François Villard André Charlebois While the content of the English version differs slightly from the original, most of the important news will be published in English. In the near future, QUEBEC City more and more of the content of the original will be translated into English. Gilbert Marquis (418) 651-1176 With over 500 visitors per day on average, spending over 13 minutes per visit, the website of InfraStructures in one of the most important sites of this kind. More than two thirds of the visitors come from outside Canada. -
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. -

Born As Twins - Papermaking and Recycling
1 Born as twins - papermaking and recycling Boris Fuchs, Frankenthal, Germany Abstract: It will be shown that in the year 105 AD., when the purchasing administrator at the Chinese Emperor’s Court, G-ii Ltm, invented, or better said, recorded the papermaking process, it was common practice to recycle used textile clothes, fishing nets and the hemp material of ropes to get a better and cheaper (less labour intensive) raw material for papermaking than the bark of mulberry trees, bamboo and china grass. When the art of papemaking, on its long march through the Arabian World, came to Europe, used textile rags were the only raw material, thus recycling was again closely related to papermaking, and to secure the paper-maker’s business base, it was strictly forbidden to export textile rags to other countries. Despite heavy punishments, smuggling flourished at that time. The &inking process was invented in 1774 by Julius Claproth and bleaching by Claude Louis Berthollet in 1785, but with the introduction of ground wood in 1845 by Friedrich Keller, recycling lost its preferential status in the paper manufacmring industry by the second half of the 20ti century, when economic considerations, especially in Central Europe, caused its comeback, long before ecological demands forced its reintroduction and environmental legislation was set in place. Thus recycling with papermaking is not an invention of the present time, but a twin arrangement right from the beginning. For the future, a certain balance between primary and secondary fibre input should be kept to avoid any collapse in the paper strength by too often repeated recycling., also to assist the forest industry in keeping our forests clean and healthy. -

Weichelt certifies that this is the approved version of the following dissertation: A HISTORICAL GEOGRAPHY OF THE PAPER INDUSTRY IN THE WISCONSIN RIVER VALLEY ________________________________ Chairperson Dr. James R. 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. -

PEER-REVIEWED ARTICLE bioresources.com The Influence of Different Types of Bisulfite Cooking Liquors on Pine Wood Components Raghu Deshpande,a,* Lars Sundvall,b Hans Grundberg,c and Ulf Germgård a In this laboratory study, the initial phase of a single-stage sodium bisulfite cook was observed and analyzed. The experiments were carried out using either a lab- or a mill-prepared cooking acid, and the cooking temperature used in these experiments was 154 °C. Investigated parameters were the chemical consumption, the pH profile, and the pulp yield with respect to cellulose, lignin, glucomannan, xylan, and finally extractives. Cooking was extended down to approximately 60% pulp yield and the pulp composition during the cook, with respect to carbohydrates and lignin, was summarized in a kinetic model. The mill-prepared cooking acid had a higher COD (Chemical Oxygen Demand) and TOC (Total Organic Carbon) content than the lab-prepared cooking acid and this influenced the pH and the formation of thiosulfate during the cook. It was found that the presence of dissolved carbohydrates and lignin in the bisulfite cooking liquor affected the extractives removal and the thiosulfate formation.

C. Tilgman in 1866-1867, using calcium as the base to manufacture paper pulp from wood (Rydholm 1965; Sixta 2006). The first sulfite mill was started in Bergvik, Sweden in 1874, using magnesium as the base (Sjöström 1993). -

CHANGES IN PRINT PAPER DURING THE 19TH CENTURY AJ Valente, ([email protected]), President, Paper Antiquities When the first paper mill in America, the Rittenhouse Mill, was built, Western European nations and city-states had been making paper from linen rags for nearly five hundred years. In a poem written about the Rittenhouse Mill in 1696 by John Holme it is said, “Kind friend, when they old shift is rent, Let it to the paper mill be sent.” Today we look back and can’t remember a time when paper wasn’t made from wood-pulp. Seems that somewhere along the way everything changed, and in that respect the 19th Century holds a unique place in history. The basic kinds of paper made during the 1800s were rag, straw, manila, and wood pulp. -
