5 anti-surge control parameters
Thread Content
The anti-surge control of the centrifugal compressor has flow rate on the horizontal axis and pressure ratio on the vertical axis, with 5 parameters for control. The inlet has three parameters: flow rate of 47,000 m3/h, 50,000 m3/h after compensation, temperature of 35°C, and pressure of 0.5 MPa. Two parameters for export: temperature 105°C, pressure 0.5 MPa. Ultimately, a command is sent to the anti-surge valve. Discussion: 1. How is the flow rate calculated after temperature and pressure compensation? 2. The inlet flow rate, inlet pressure, and outlet pressure are easy to understand in terms of their role in anti-surge control; it’s not clear why the outlet temperature is involved in this control as well I would appreciate it if colleagues at HaiChuan could help answer my questions or recommend books or article titles so that I can search for them.
Temperature causes gases to expand, leading to changes in flow rate and pressure. For details, see the ideal gas law
1. Why are the inlet and outlet pressures of your compressor the same? 2. Except for mass flowmeters, temperature and pressure corrections are required for gas flow measurement
