Cost‐Saving Through early Recognition of Abnormal Wear Conditions Introduction Residual abrasive contaminants in new process units can cause rapid wear of rider bands in reciprocating compressors. Those abnormal wear conditions can be detected at an early stage by continuously monitoring the proximity measures with the help of a PROGNOST®‐NT monitoring [...]
Early Failure Detection and Shutdown of a Compressor Due to Crosshead Fracture Timely Shutdown Ensured with Modern Monitoring and Machine Protction Systems A PROGNOST Systems customer in Germany operates four, four-cylinder reciprocating compressors at a natural gas production facility in Northern Germany. This case study describes the detection of critical [...]
Enhancing Reliability of a Hydraulically-Driven Hyper Compressor By Mirko Graf from Innospec Leuna GmbH Client Overview Innospec Leuna GmbH, part of the global specialty chemicals company Innospec Inc., operates a plant in Leuna, Germany, producing EVA-based products such as FLEXAREN® and VISCOWAX®. The plant includes a hydraulically-driven Hyper Compressor commissioned [...]
Proximity measurement to detect a fractured piston rod Successful avoidance of major consequential damages using proximity measurements to detect a partially fractured piston rod By Uwe Ladwig One day, the online monitoring system at the Yara Brunsbüttel (Germany) urea plant site avoided compressor damage by detecting a cracked piston rod [...]
H2 compressors at refinery show abnormal wear conditions Residual abrasive contaminants in new process units can cause rapid wear of rider bands in reciprocating compressors. Those abnormal wear conditions can be detected at an early stage by continuously monitoring the proximity measures with the help of a PROGNOST®‐NT monitoring system. [...]
Impact Versus Impact - Comparison of Different Filter Modes for Vibration Measurement Watch the case study on YouTube: https://youtu.be/SHe9j08Fprw?si=sYBMldNDd_23rlJa Root cause analysis, impact detection and verification for reciprocating machinery such as piston and hyper compressors are always challenging. When talking about condition monitoring of reciprocating machines, vibration signals are an [...]
Effective Vibration Monitoring For Reciprocating Compressors Modern standards require frame sensors and more Download the case study Effective Vibration Monitoring for Reciprocating Compressors Reciprocating compressors show the highest number of damages while being process-critical at the same time. The reasons why are partially based on the higher number of [...]
