Design Performances

Usually compressor performances p2, T2,

are known in design conditions

But during the operation the compressor works with actual inlet

conditions that may be different from design ones

Cmap allows to calculate

compressor performances in new

operative conditions, i.e. with

actual gas mix composition, actual

inlet pressure, actual inlet

temperature.

Cmap allows also to analyze

performances

in new operating condition and compare

expected performaces to field measurements

Analisys Tool

Analisys Tool calculates:

• Expected discharge pressure in actual

condition

• Expected discharge temperature in actual

conditions

• Expected efficiency in actual conditions

• Expected head in actual condition

• Measured efficiency

• Measured head

• and more…
