Evaluation of LNG Train Operation Resulting from Refrigeration Compressor Re-wheel
Abstract
• In an LNG production plant, multiple propane (PR)
refrigeration compressor failures since commissioning led to
re-wheeling
• PR refrigeration system was not considered to be the main
bottleneck, nevertheless improved production rates were
realized
• Full refrigeration system machinery evaluation highlighted
the main uplift to be a result of improvement in the Mixed
Refrigerant (MR) system
• Thermodynamic coupling of upgraded PR loop with MR loop
resulted in added capacity to MR loop
