Wet End Monitoring and Control
Fiber, Ash Retention and Charge Control in the Wet End
Paper Machine wet end performance is important to create the best board, tissue and papermaking conditions. Controlling wet end stability is becoming more difficult as the number and complexity of chemicals in the wet end increases. Conmark’s Wet End Analyzer includes Retention and Charge measurements with controls that can help bring the wet end under complete control. Conmark’s wet end analyzer helps to create the best conditions for stabilizing consistencies, ash content, charge and chemical balance. Using the benefits of our proven analyzer produces improvements in quality, runnability and overall efficiency. Automatic charge control will stabilize wet end retention and provide online cationic/anionic charge measurement. Retention measurement for fibers and ash is a well known technology that utilizes multi-wavelength LED technology to measure ash and fiber consistencies in the headbox and wire pit. Combining this optical technology with streaming current measurement techniques of the charge analysis, for reliable methods of measuring process charge and determining cationic demand. This wet end charge measurement has been successfully used in many paper mill applications to help optimize additive usage and resolve runnability problems.
Pro-Eye™100 Applications
Pro-Eye™100 Remote Touchscreen Monitor (RTM) allows the user to select from the menu the applications they want to utilize with the transmitter. There are options for Consistency, Freeness, Fiber Length, Ash Content, HW/SW Ratio, Kappa, DShives, Retention, Viscosity, Brtightness, etc. The RTM can be installed 50 ft or more from the sensor location. There are 4 binary inputs, 4 relay outputs and two 4-20ma outputs. All connections are active. Intuitive, menu driven programming with 7” color touch screen makes set-up, calibration and troubleshooting simple. The RTM runs on a Windows 11 operating system which makes for easy interface.
Controls
Lower basis weights and use of cheaper raw materials is a growing trend in paper making. To improve production paper machine speeds have been increased. Retention control is critical to papermaking. First-pass retention (Retention) is the measure of the amount of solids remaining in the paper sheet when compared to the amount leaving the headbox. Retention is considered the best indicator of the runnability of the paper making process.
The ProEye 100 Retention Analyzer provides a real-time retention measurement for Fiber and Ash. The addition of a Charge Analyzer makes automatic control of the Wet End simpler. Paper machine performance is improved dramatically.
The Wet End Charge Analyzer pr vides a tool to optimize wet-end chemistry and control anionic trash. The Charge Analyzer helps quantify the effect of various additives on system charge and is a useful tool for assessing and improving process efficiency. Manufactured to require low maintenance and produce excellent reliability, the online Wet End Charge analyzer is well known technology for this measurement. The analyzer is used in process control as well as information source. Also, no chemicals are needed for measurement and all the materials are 316SS.
