Axial Compressors For Pipeline Compression Stations

摘要

This article highlights new developments and lessons learned from recent experiences in the pipeline industry in relation to 1) the selection, 2) the design, 3) the manufacturing, 4) the anti-surge systems and 4) the operation of axial compressors. Axial-flow compressors are advanced turbo-compressors used for high capacities. They considerably reduce the weight, the size and the cost of the compressor package. They offer a very compact and modern compressor solution. The axial flow is highly sensitive to the profile shape/design of rotating and static components of an axial compressor. Another important factor is the rotor stability towards (near) stall/surge conditions, which is directly linked to the axial compressor operating range.
