In a competitive environment, profitability of chemical units is critical. To reach expected outputs ratios, production units' availability and reliability are keys. Lubrizol France improve reliability of agitators and pumps on batch units to secure production and outputs while batches running. Thanks to vibration monitoring solution and associated services, Lubrizol team anticipated several mechanical damages, saved more than 400k€ and improve global reliability of production unit. With a Return of Investment (ROI) lower than 2 months on first pilot, Lubrizol deployed predictive maintenance and vibration monitoring on 29 essential assets in France. Currently Lubrizol is quantifying real and concrete gains made for 1 year and took decision for standardizing MHM for all Lubrizol sites.
