Our first step was to provide an onsite audit of the existing controls of their recycled paper process. We then designed an automated control system for the paper machine. The Quad Plus engineers specified and procured the instrumentation and control devices. Our design included a Siemens PLC system, flow and pressure transmitters, control valves, consistency transmitter, and a gauging system for basis weight measurement. We then developed the control software and provided a Wonderware SCADA system.
The result for the customer was the ability to control the paper machine through the visualization system using a single operator. The customer was also able to ensure a consistent paper grade, which reduced the raw materials consumed during production.
