Abstract Maximizing Compressor Performance Process engineering services monitoring compressor performance is vital to successful maintenance of plant efficiency and energy use. Process gas compression equipment is key in moving process fluids through chemical equipment as well as providing the necessary pressure to promote chemical reactions. An Ammonia plant Process Air compressor was upgraded with high efficiency impellers, diffusers and improved seal technology with resultant performance improvement monitored for three years. The compressor originally was designed employing 1970s technology, and the upgrade improved capacityabout 15%, while improving stage efficiencies by about 6% Polytropic efficiency gain. The article highlights the benefits of monitoring, improving and preserving compressor efficiency. Process gas compression equipment is essentially the Heart of plants, moving process fluids through chemical equipment as well as providing the necessary pressure to promote chemical reactions. This article highlights maintaining and improving the performance of centrifugal compressors. Centrifugal compressors by their design have inherent aerodynamic and thermodynamic performance and efficiency characteristics, dependent on size, shape and the number of impellers as well as the condition of shaft and inter-stage seals.
