Dear all,

Can anyone help me on the same question of "asma", above?

Should we use "adiabatic compressor" of the DWSIM, to simulate gas blowers in the conditions?

The blower conditions are:

Volumetric flow: 5.000 Nm3/h
Outlet pressure: 1065 mbar.
Inlet pressure: 865 mbar

Thank you all!

Hello,
I would use a compressor with a polytropic efficiency of 0.58, correspondig approx to 0.57 isentropic efficiency considering air as handled fluid.
Hope it helps.

  Hello, Luca!
  
  We are working with biogas (biomethane). Any idea about this situation?

Hi Pedro,

I would consider a blower isentropic efficiency in the range 0.55 to 0.59 and calculate the polytropic efficiency as function of gas (cp/cv) and compression ratio (see attachment).

Hope it helps.
