Reciprocating Compressor Pulsations Effect on Compressor Surge Margins

摘要

Pressure suction/discharge pulsations in pressure and flow can move a centrifugal compressor into surge and affect its performance. In mixed pipeline compressor stations where centrifugal compressors operate in series or parallel with reciprocating compressors, this is of special concern for operational range and safety reasons and must be considered during the design process. Thus, testing of reciprocating and centrifugal compressor mixed operation was performed in an air loop at the SwRI compressor laboratory.
