Innovative Chemistry Solutions from Pruszynski Paper Chemistry, LLC

Over 30 years of industrial experience Przem participated in the projects on 150+ paper machines in all regions of the world in the following major areas:

• Selection and optimization of chemical applications: retention and drainage, pitch and stickies control, internal sizing, strength control
• Troubleshooting runnability and quality problems - holes, breaks, defects, deposits, printability 
• Optimizing system-wide chemical applications and transforming them into simple, cost-effective, finely tuned chemical program
•  Focusing on the compatibility of all applications and optimal chemical conditions in the system 
• Assisting with all chemistry aspects of new grade development - defining needs, selecting programs, training personnel
•  Brightness development, brightness preservation of mechanical pulps - reducing cost and impact on wet end chemistry of the system
• Mill closure and its impact on wet end applications
• · Introduction or increasing content of market mechanical pulps in the furnish 

• Machine efficiency increased by 6% through redesigning pitch/stickies control program after neutral pH conversion
•  Assisted mill in the wet end chemistry stabilization for the hydrogen peroxide bleached TMP system resulting in 5% efficiency improvement and reaching new grades specifications
• AKD persisting press deposition reduced significantly through fine-tuning addition point and improving colloidal retention
• Developing a chemical program for newsprint mill converting to packaging grade
• Troublesome deposits of rosin acids on the offset printing machine eliminated through introduction of pitch control program including organic fixatives and inorganic adsorbent
• Missing dots problem in SCA+ roto product eliminated through improved filler retention
• High level of troublesome sulfites reduced by 60% by optimization of hydrosulfite bleaching of mechanical pulp
• Filler retention in the highly contaminated furnish increased, and retention program costs reduced by innovative filler pre-treatment strategy
