Optimize cracked-gas compressors with smart-automation technology

Machine health monitors can provide critical information to avoid unit and plant-wide shutdowns

Keywords: [olefins] [ethylene] [compressors] [maintenance] [cracked-gas compressors] [valves]

The cracked-gas compressor (CGC) is the single most critical piece of equipment in an ethylene plant (Fig. 1). This asset can cost as much as $50 million and operates 24/7 under demanding conditions. Because it has no backup, ethylene producers know that if their CGC trips—whether the trip is caused by excess vibration, a surge, an instrument malfunction or other problems—their entire ethylene process may be halted for up to a week.
