Title: Power of spectroscopy for chemical recovery & stickies monitoring

Presented by: Dr. Jonathon Speed, CCHem, Product & Applications Manager

Overview: Spectroscopy has the power to directly observe chemicals present in a sample. Monitoring chemical concentrations from on-line analysis is recognized as having the potential for significant impact on a range of pulp & paper processes; for example, improving chemical recovery efficiencies, or enabling real-time stickies monitoring. However, not all spectroscopies are the same. The most robust techniques – such as NIR – can be used on-line but tend to have low information levels. The more informative – such as FTIR – are unfortunately more fragile and need to be lab based inhibiting the ability for real-time measurements. A third option, the IRmadillo on-line FTIR, crosses the robustness of NIR with lab-based performance of an FTIR. 

Here we’ll talk about the power behind spectroscopy, what makes each method different, the chemistry involved with monitoring reduction efficiency and stickie formation and efforts to analyze them on-line. More importantly, you’ll learn how advancement in analytical technology enables process optimization with real-time measurement.

Learning Outcomes:
1. Understand the current top challenges with capturing on-line chemical concentration analysis in pulp and paper manufacturing
2. Describe the fundamentals of spectroscopy to enable process optimization in pulp and paper manufacturing
3. Distinguish strengths and weaknesses of near-infrared (NIR) and mid-infrared (FTIR) spectroscopies as in-process analytical techniques
4. Examine the basic chemistry involved in monitoring reduction efficiency and stickies formation
5. Assess how the IRmadillo and on-line spectroscopy can address analytical issues with real-time information for improved chemical recovery, monitoring the formation of stickies and overall process optimization
