While the Industrial Internet of Things (IIoT), augmented reality and digital twin technologies have engineers dreaming of future possibilities, it is important that plants not disregard the fundamental issues—i.e., enhancing productivity and reducing unscheduled downtime—that have been around for decades. New, imaginative technologies could provide operators better visibility into asset health and improve production uptime. And, while the possibilities of these technologies are certainly worth waiting for, advancements in industrial wireless technologies can deliver many of these benefits today. While some industrial wireless technologies have existed for more than a decade, chemical plants have been slow to adopt them because of concerns regarding connectivity, reliability and security. In fact, at most chemical plants, fewer than 20 percent of pumps have any instrumentation at all. Most of the instrumentation that does exist is not wireless and is only used to monitor critical assets such as turbines, compressors and other large rotating equipment. How do these plants monitor their remaining assets? They rely on third-party service providers to inspect their equipment manually. Technicians or contractors walk the plant with handheld devices to collect vibration data on each piece of rotating equipment. Given that an average chemical plant has an installed base of 5,000 pumps, third-party providers manually collect data on 4,500 pumps monthly. Assuming a technician can check 60 pumps in a day, it would take about three full-time employees 30 days each to collect data on all 4,500 pumps. Most chemical plants inspect pumps once or twice a month.

This data can be stored on the plant’s network so the control center continuously monitors assets and notifies technicians of problems. Reliability engineers can proactively access data 24/7, which enables them to set parameter thresholds with automatic alerts as soon as an anomaly is detected rather than waiting on a call from the control center. Both control center notification and proactive access to data are effective methods of addressing an anomaly.
Daily reports can be provided to vibration analysts for a detailed analysis and suggested corrective actions. By focusing efforts on the equipment that needs attention, plants can improve asset reliability while also improving the productivity of their reliability and maintenance engineers.
