Maintenance: Pursuing Improvements in Rotating Machinery

By Kirill Grebinnyk and Bob Krusemark, Sulzer |

The variety of rotating equipment used in chemical manufacturing creates the need for diverse maintenance methods. Using new techniques can greatly improve the reliability and performance of all types of rotating machines The processes that are required to manufacture chemicals on an industrial scale rely on a large variety of rotating equipment to deliver the end product. From steam turbines and electric motors to compressors, expanders and pumps, every machine has a vital role to play. Keeping the manufacturing process running requires dedicated maintenance teams and expert knowledge to deliver reliability and performance. Installed pieces of rotating equipment are operated for numerous years — decades in many cases — and at some point, will begin showing signs of age. In some cases, the original equipment manufacturer (OEM) may no longer support the older models or may even have ceased to exist. In other situations, the lead time for a major overhaul may not match the expectations of the plant owner. Whatever the case, modern design and manufacturing processes can be applied to time-served equipment and deliver cost-effective improvements.   Managing power and efficiency From onsite generators to the numerous electric…
