      <abstract xml:lang="ru">
        <p>Образование минеральных отложений является одной из основных причин вынужденных остановов варочных установок типа «Камюр». В настоящее время применение ингибиторов является одним из наиболее эффективных и дорогостоящих методов борьбы с солеотложениями. Именно поэтому правильный подбор ингибитора и его дозировки необходимы для достижения бесперебойной и экономически целесообразной работы оборудования. При этом требуется установление природы минеральных отложений и уровня содержания вызывающих их веществ. Результаты анализа образцов минеральных отложений варочных установок непрерывного действия типа «Камюр», отобранных на двух различных производствах действующего целлюлозно-бумажного предприятия Российской Федерации во время вынужденных остановов, подтвердили, что углекислый кальций является их основным компонентом. Преобладающим процессом, приводящим к образованию карбонатных кальциевых отложений в условиях варки целлюлозы, является взаимодействие ионов кальция и карбонат-ионов. Неустранимый источник карбонат-иона – белый щелок. Катион кальция в большем количестве поступает с древесиной (до 1,6 кг/т а.с.в), в меньшем – с белым щелоком (вследствие длительности реакции каустизации), и наименее значительно – со слабым черным щелоком, направляемым для поддержания гидромодуля варочного котла. Представлены уровни варьирования содержания карбоната натрия и катионов кальция в используемом сырье, их часовое поступление с учетом реальной производительности варочных установок и укрупненный баланс по кальцию для обследованных варочных установок непрерывного действия типа «Камюр» на производстве лиственной и хвойной сульфатной целлюлозы.</p>

        <p>Mineral deposits are one of the main causes of unplanned shutdowns of Kamyr digesters. Currently, the use of inhibitors is one of the most effective and expensive methods for dealing with salt deposits. Therefore, the correct selection of an inhibitor and its dosage is essential for ensuring the smooth and cost-effective operation of the equipment. This requires determining the nature of mineral deposits and the concentration of the substances that cause their formation. We analyzed the mineral deposit samples from the continuously working Kamur digesters selected at two different production lines of an operating pulp and paper mill in the Russian Federation during forced shutdowns. The analysis results confirmed that calcium carbonate is the main component of the deposits. The predominant process leading to the formation of calcium carbonate deposits during the pulp cooking process is the interaction of calcium ions and carbonate ions. White liquor is an unavoidable source of carbonate ions. Calcium cations are introduced in large quantities with wood (up to 1.6 kg/t of dry matter), in smaller quantities with white liquor (due to the prolonged causticization), and in even smaller quantities with weak black liquor, which is used to maintain the digester’s water level. The paper presents the variation in sodium carbonate and calcium cation content in the raw materials used, their hourly intake considering the actual performance of digesters, and a consolidated calcium balance for the examined continuously working Kamur digesters at the production of hardwood and softwood sulfate pulp.</p>
