Pulp and Paper Industry Dependable online, inline, and atline solutions for your papermaking needs. Benefits of online monitoring in the pulping process 02 The pulp and paper industry is full of difficult processes Metrohm Process Analytics offers several analytical and aggressive matrices. In order to run each part of the tech niques in many different analyzer configurations for papermaking process optimally, constant quality checks any need: titration, photometry, ion chromatography, and analyses should be performed. Analyzing crucial NIR spectroscopy, and ion­selective measurements. pro cess parameters inline, atline, or online instead of Our online process analyzers and custom sample pre ma nual offline laboratory analysis saves time and op conditioning systems are manufactured in the Netherti mizes process efficiency while reducing operation lands and supported by our local service engineers cost. Real time analysis as an integrated part of process world wide. control and automation will help you increase yields and improve production quality. Kraft Process This is the dominant pulping process with the highest boiler to the causticizing plant. Frequent, reliable online chemical recovery efficiency. Sodium hydroxide and so measurements lead to a more effective process, better dium sulfide, the main chemicals used to pulp wood quality of the white liquors for reuse in pulp production (also known as liquors) are monitored in several stages and energy savings by efficient generation of high of the cooking process from the digester to the recovery pressure steam. Sample preconditioning Online sample preconditioning systems lower maintenance costs and help analyses run more smoothly. Metrohm Applikon can provide a complete and exact solution for almost any application due to more than 40 years of experience in process analytics. Projects range from one analyzer in combination with simple sample preparation to complete turnkey packages with shelters, piping, wiring and interfacing. Settlers instal ed on­site for some of our process analyzers in pulp and paper mil s. Applications Online or atline analysis of pulping liquors 03 The Process Analyzer ADI 2045TI is suitable to analyze White, Green, Black, & Wash liquor with multiple sample lines outputting results for closed loop control. For atline analyses, the ProcessLab ADI 2045PL is typical y used for multiple sampling points and parameters that do not require fast response times or frequent analysis. • Conformity to SCAN­N 30:85 – Effective, Active, and Total Alkali in pulping liquors • Carbonate • Hydroxide • Sulfide • CE% (causticizing degree) • and many more ProcessLab ADI 2045PL Sulfate Measurement by Thermometric Titration Sulfate concentration can be easily measured with ther mometric titration. Metrohm is currently the on ly ma nufacturer on the market offering online thermo metric titration, and the 2035 Thermometric Process Analyzer is ideal for this application. Combined with the ABC titration results from the 2045TI, this gives a perfect indication for the degree of reduction and information about the recovery boiler efficiency as a reactor. • Enthalpy change of the reaction is monitored • Robust probe is resistant to aggressive samples • No sensor calibration or maintenance required • Fast and accurate results: Thermoprobe response Process Analyzer 2035 Thermometric time of 0.3 s with a resolution of 10–5 K Spectroscopic applications for papermaking For fast, reagent­free, nondestructive analyses, nearin frared spectroscopy can be used. Metrohm Applikon offers two NIRS lines: XDS and PRO. The NIRS PRO can be con fi gured for contact and noncontact measurements, while the XDS can handle up to 9 measuring points. These analyzers come with a wide portfolio of fiber optics and probes ready to handle any sample. • Kappa number • Moisture • Lignin content • Resin • Kraft pulp yield • Brightness • Tall oil • Wood species NIRS XDS Process Analyzer NIRS Analyzer PRO • Coatings • Hardwood/Softwood ratio • Component analysis (clay, TiO , fil ers, ash, etc.) 2 Other important parameters Metrohm Process Analytics offers much more than what No matter what application, our turn­key process solucan be outlined here. We also offer complete process tions from Metrohm Process Analytics are indis pensable solutions for other areas, such as analysis of Ca and when it comes to increasing throughput and saving Mg in brine in the production of Cl for bleaching. The money in your plant. 2 Process Ion Chromatograph is suitable for measuring either organic acids or sulfur species in process water or even trace impurities in steam in order to protect the turbines from excessive scaling, for example. www.metrohm.com V. witzerland ohm Applikon B. ­9100 Herisau, S G, CH ­09 ohm A Subject to change without prior notice Layout by Alyson Lanciki, Metr Printed by Metr 8.000.5221EN – 2017
