Pulp and Paper System Integrator Offering Automation Services
Increase Productivity for Your Pulping and Papermaking Processes
You have to respond to the challenges of the pulp and paper industry: tightening competition, operations and raw material price increases, and compliance with strict environmental and safety regulations. It is important for you to automate and optimize your paper and pulping processes, extend your current equipment’s lifespan, while keeping improvement costs and shutdown time to a minimum.
What is necessary to maximize safety and increase productivity while reducing energy and lifecycle costs? Seamless engineering solutions. Quad Plus can meet the demands of your pulp and paper production processes.
Why Quad Plus?
Even though you need to maximize operating time, you also should implement changes to increase efficiency on your existing paper machine or winder. How do you do this? By working with a trusted partner that will precisely evaluate your current processes and capture efficiencies through process performance and control automation improvements.
Quad Plus has the paper production process experience to assess your current operations and provide customized solutions to reach your specific paper mill productivity targets. During the design phase, we utilize advanced process control technologies to model and verify system behavior before implementation to mitigate shutdown time. The same engineers that design your solution then perform onsite installation and commissioning of the entire system. This consistency ensures that newer technology and controls work as intended with your existing equipment.
Pulp and Paper Application Challenges
Pulp and Paper Line Optimization
You’ve already optimized a section of your line hoping to increase capacity, but then begin experiencing a bottleneck or slow down of subsequent segments. To resolve these unintended consequences, the entirety of the web handling process should be evaluated to determine where improvements must be made.
The evaluation starts with an understanding of all current control systems and process capabilities, new technology potential, and the different characteristics of the product as it feeds through the machine. Then, using advanced process control modeling, solutions can be designed to mitigate control speed differentials that accrue at different sections. The result is to maximize the efficiency of paper manufacturing without causing unforeseen issues further down the line.
Motor and coordinated drive systems should be selected and designed for each section based on normal running load (NRL) and recommended drive capacity (RDC) calculations. Sectional motors load-sharing capabilities also contribute to determining the power required to account for speed differentials in other sections.
Control systems must monitor, process, and respond to operating condition variations in each section. Removing slowdowns and bottlenecks to the winder is critical to optimize performance. High speeds, adjusting motion control, precision tension, and efficient control communication are necessary capabilities. These allow for rapid, dynamic changes to speed and torque while ensuring the product is unwound from parent rolls, slit, trimmed, and rewound without damage.
Pulp and Paper Process Design and Automation
Implementing new process control methodologies can address inefficient actions throughout the entire papermaking process. The results can include extending the life of your existing equipment while reducing changeover times, increasing speed, capacity, and productivity, and stabilizing product quality control.
Automating paper grade and parent reel changes, slitter adjustments, and blade changes can have a significant impact. Plus, rebuilding inefficient sections of the line can supply measurable returns on your investment. Automating risky manual processes also increases overall safety. Your personnel can manage recipes, paper grade changes, and slitter adjustments from outside the paper machine and winder.
Online Paper Profile Measurements
Web gauging system integration allows for real-time, continuous measurement of paper thickness, basis weight, moisture, machine direction (MD) and cross-machine direction (CD) tension profiles at critical points. Monitoring and correcting profile and quality disturbances improve wet end stability, reduce product variances, chemical usage, and paper web breaks resulting in increased productivity and capacity.
As the quality measurements are scanned, data is stored in a database for further reporting and analysis after production. The reporting tools allow identification and comparison of product qualities to determine the root cause of issues.
