WET END ANALYZERS: NEW GENERATION OF ANALYZERS
MONTREAL, QC — BTG launched Particle Charge Titrator (PCT) 20, a new on-line analyzer for enhanced wet end control, to paper mills that wish to optimize performance and enhance wet end chemical efficiency.
The PCT 20 provides a new tool for controlling charge in the wet end. Commonly, it is used for controlling the incoming furnish charge demand with coagulant or fixing agents, so that other downstream additives are applied more efficiently and economically. Optional modules for the measurement of turbidity in filtrate, pH and conductivity provide additional information necessary for coagulant and process monitoring.
VALVES: BUTTERFLY VALVES FOR PERFORMANCE
MINNEAPOLIS, MN — DeZURIK Intelli-Seal HP Butterfly Valves is a four-inch, high performance valves that control the flow of a heat transfer fluid used to alternately heat and cool a reactor of tall oil — a type of pine oil by-product from pulp and paper manufacturing.
Conventional ball valves previously used in the heat transfer fluid system leaked under 300C, differential across the valves in the system. Tight shutoff was an important characteristic of valves needed for this application. In on/off or isolation applications, butterfly valves with high performance seats are often the better choice over ball valves when tight shutoff is a requirement.
PAPER DUST EXTRACTION: DUST-FREE PAPER
WINDSOR, CT — Krber PaperLink’s subsidiary, E.H.C. Will, and the Swiss Patent Consulting and Development, are cooperating in the area of paper dust extraction. The patented SCHNEIDER XT400 from Switzerland allows paper to be made dust-free by creating a vacuum on the paper surface. A precise curve on the dust extraction head is used to control the airflow such that the dust-laden air is channeled away via the air duct into the vacuum.
