Modification of Performance Curve of Centrifugal Ammonia Compressor

DONG Hualin;LOU Lunwu;Guizhou Chitianhua Tongzi Chemical Co., Ltd.;Guizhou Xiyang Industry Co., Ltd.;  
Due to actual operating flow at the first inlet of the centrifugal ammonia compressor deviating from the design value, the designed anti-surge curve of ammonia compressor could not meet the production requirements, and the anti-surge valve was opened to maintain production. Especially when the load was low, most of the inlet gas of the first section was in the state of self-circulation, causing unnecessary energy loss. Through the measured surge point, the anti-surge curve of ammonia compressor is modified, and the economic operation of ammonia compressor was realized.
