Consistency Measurement and Basic Tenets of Loop Design (PC6.4)

A strong consistency measurement and control is considered by some to be a lost art as many pulp and paper mills struggle with good a Consistency Measurement Program.  The challenges are usually based on improper sensor selection, location, and sampling techniques.

This presentation will address current measurement technology and proper selection based on specific application and mill requirements.  Attendees will gain insight into proper sampling and sample data analysis to achieve the highest accuracy and repeatability possible. Additionally, basic consistency control loop guidelines, such as dilution systems, agitation, and dilution valve selection will be reviewed.

Measurement of S and Na Distribution in Impregnated Wood Chip by XRF (PC8.2)

With increased demand to replace plastics, especially as packaging material, with renewable, easy to recycle and compostable materials, there is a greater need to improve the fundamental scientific understanding of pulp and paper manufacturing systems. This has resulted in a renewed focus on high yield pulping (HYP) processes, such as CTMP, for packaging material as well as manufacturing of hygiene paper.

A key unit operation when producing CTMP is the pre-treatment of wood chips before defibration. In order to separate the wood to individual fibers with minimum amount of electricity it is necessary soften the lignin. The lignin is softened by means of a combination of sulphonation at high pH and elevated temperatures in the preheater and in the refiner, where the fiber separation occurs.

It is challenging to create a process technology that gives an even distribution across the wood chips of the sodium sulphite containing liquid used for impregnation.

This presentation highlights a new methodology that measures the sulphonation degree on a detailed level, thus improving the impregnation technology.

Keit Spectrometers

An Online and Real-time Process Analyser for Closed-loop Control in Pulp & Paper Manufacturing (PC5.2)

Real time analysis of manufacturing is an area of intense interest at the moment due to Industry 4.0 and recent developments in technology. Whilst online parametric measurements – such as pH, temperature, color measurements and conductivity – allow for some limited control through inferential models, it is spectroscopy based analyzers that show real, long-term potential.

Near infrared spectroscopy (NIR) has been trialed extensively in various industries, but it suffers from poor sensitivity and very poor chemical specificity and selectivity. Mid infrared (also called FTIR) offers significantly better performance but traditional FTIR instruments need fragile fiber optic cables and probes that make the instruments wholly unsuitable for manufacturing environments.

This presentation highlights a static optics FTIR spectrometer with a fiber-free probe that gives the performance of FTIR spectrometers with the reliability and robustness of NIR. Attendees will learn how it performs using a range of chemicals and about its potential use in lignocellulosic processing to improve savings in the higher value aspect of the pulp and paper manufacturing as well as the core processes.

Future of MES - Towards Autonomous Mills (M5A-PC3.2)

The fiber-based industry is transforming as mills look toward data solutions to increase efficiency and maintain flexibility. Obtaining a seamless combination of the automation world and the IT world moves digital information of the shop-floor to a new level. Manufacturing Execution Systems (MES) act as a multiplier of efficiency for asset intensive production. With more autonomous mills, leading producers can create the best possible context for data-driven decisions – automatically balancing both customer satisfaction and profitability.

Today's MES must capitalize on data-based learning models and run pulp and paper mills semi-autonomous for years to come.  More data has increased the demand for seamless integration resulting in greater optimization and flexibility.

This presentation will highlight the evolving role of MES and the future needs of a practical solution architecture enabling autonomous mills.

Analysis of Roughness Measurements of Coated Cardboards (PC5.1)

A popular method to measure the roughness of paper and cardboards is presented in the ISO 8791-4:2007. This specification is for “coated and uncoated papers and paperboards which are intended to be printed by contacting printing processes.” Consequently, the adaptability of Parker Print Surf (PPS) for digital printings has to be analyzed closer.

This study focuses on profile roughness and area roughness analyses by means of a 3D laser scan microscope. One aim is to understand how these both methods differ of each other and from PPS measurements. In addition, it is of interest whether roughness shows a correlation on density and remission values of pigment and dye based inkjet inks. The measurements were correlated, using Pearson, Coefficient of determination r2 and Spearmen.
