Abstract: The main air compressor is the core equipment in the large internal compression air separation unit, and its anti-surge

control and the selection of venting valve are the key to stable daily operation. This paper takes the Rikt140-4 centrifugal

compressor produced by Man Company in Germany as an example, analyzes the single valve control scheme and double valve

control scheme in detail, compares the operation of compressors using different control schemes and gives selection suggestions, and

defines the double valve control scheme or single GLBOE valve control scheme as the preferred scheme to help the compressor run
