Optimize cracked-gas compressors with smart-automation technology
Machine health monitors can provide critical information to avoid unit and plant-wide shutdowns
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 tripswhether the trip is caused by excess vibration, a surge, an instrument malfunction or other problemstheir entire ethylene process may be halted for up to a week.

Compressor operation must be fine-tuned to maximize performance and reduce spurious trips tha
