IIoT for Pulp and Paper Manufacturing: How to Monitor Digesters, Paper Machines, and Recovery Boilers in Real Time
· 9 min read
Pulp and paper manufacturing is one of the most energy-intensive and capital-equipment-heavy industries on the planet. A single paper machine can cost $500 million, run 24/7 for years between major shutdowns, and produce 1,500+ meters of paper per minute. When it stops unexpectedly, losses mount at $50,000 to $200,000 per hour — and that's before you count the quality rejects from the restart sequence.
Yet many pulp and paper mills still rely on 20-year-old DCS systems, clipboard-based maintenance rounds, and operators who "listen to the machines" to detect problems. In an industry with razor-thin margins (typically 5-10% operating profit), the gap between reactive maintenance and predictive monitoring is the gap between profit and loss.
