05 CC Off Designe Operating Overview

The document discusses compressor operation off design conditions. Compressors are designed for specific inlet conditions but may experience different actual inlet conditions during operation. This can change the inlet pressure, temperature, or gas molecular weight. When inlet conditions vary from design, the compressor must operate off design. Examples given of factors pushing operation off design include fouling, which decreases efficiency, and internal leakage or recirculation, which also decreases efficiency.
