Modeling of Kraft Mill Chemical Balance
… on sodium (Na) and sulfur (S) balances in the kraft pulping process. In order to maintain a proper balance of Na and S, kraft mills may need to adopt different makeup strategies. For this purpose, a dynamic model was developed to predict the Na and S balance in the kraft recovery cycle, as well …

Ordens kraft : Politiska eder i Sverige 1520-1718
Political oaths were widespread in medieval times, but all over Europe their use dwindled in the early modern period, resulting in the institution being dismantled in many states. In previous research, this decay has been explained by pointing to the emergence of the state in this period, through …

Numerical Simulation of Kraft Recovery Boiler Sootblower Jets
The fouling of heat transfer surfaces in kraft recovery boilers is a significant concern for the pulp and paper industry. The usual approach to controlling fouling is the use of so-called ``sootblowers,'' that utilize boiler steam to generate supersonic steam jets that are literally used to knock …

On site measurements of kraft pulp pump system efficiency
With increasing energy costs and competitive pressures, interest has increased in surveying installed pumps for potential energy savings. Field pump efficiency tests are required to assess pumping performance and help to identify improvement opportunities. This work concerns the on-site …

Die Alternative für Deutschland - eine parlamentarische Kraft wie jede andere?
… AfD eben nicht wie jede andere parlamentarische Kraft thematisiert werden kann. Dies ergibt sich aus dem Ergebnis der Analyse. Nach einem Überblick über das öffentliche Gebaren namhafter Vertreter/innen der Partei sowie einer groben ideologischen Einordnung anhand der AfD-Programme folgt eine …

Kraft lignin as a fuel for the rotary lime kiln
For many kraft pulp mills the chemical recovery boiler, in which concentrated black liquor is burned, represents the principal obstacle to increased production. However, studies have shown that the removal of even a small portion of the lignin from the black liquor would permit an incremental …

Alum treatment of caustic wash from chlorine bleached kraft pulp
… treatment of caustic wash from chlorine bleached kraft pulp, to determine if a double tray Dorr thickener could be used to settle the coagulated waste, and to determine if a centrifugal separator could be used to dewater the sludge from the Dorr underflow. Approximately 5000 gallons of caustic …

Ageing Assessment of Power Transformer Kraft Paper Insulation Using Optical Speckle
… in electric networks. Copper windings wrapped in kraft paper and immersed in a tank of mineral oil are their main composition. Oil-impregnated paper is a very common insulator in power transforms, due to its durability and endurance. Kraft paper, a wood-based fiber from cellulose, can gradually …

Changes in accessibility of cellulose for kraft pulps measured by deuterium exchange
… the chemical refining of wood, including kraft pulping, bleaching, drying, and further processing of the pulp. The characteristic physicochemical conditions in each subprocess were simulated with laboratory setups. In part, the analysis was based solely on literature. Cellulose …
