| Abstract: | This paper explains the causes of surges occurring in a centrifugal compressor, and expounds the anti-surge methods and measures for the centrifugal air compressor used in the first set of home-made large air separation unit up to 40,000 m^3/h. Actual application testifies that no surge has occurred since this control was put into use. The operation is safe and reliable, which proves that this control conception is feasible and worthy to be spread. |
