An ethylene plant has a number of very large, very critical compressors which will cause the entire plant to shutdown if they ever trip. The cracked gas compressor increases the entire cold-side feed from around 3 psig to ~475 psig, typically through 5 stages. The two refrigeration compressors are the next biggest compressors that can also shut down the entire plant if they trip.

An Asian refiner sought to improve reliable operations around their control valves a decade ago. I caught up with Emerson’s Sumitaka Ichiki who shared the story of their journey to more reliable operations. Using the Fisher FlowScanner valve diagnostic software, they analyzed the dynamic response of many of their critical valves. Based on their findings, […]
