How to select and calculate the startup outlet temperature for a reciprocating compressor
Thread Content
Regarding reciprocating compressors, how are the outlet temperature and pressure calculated after a hot start-up? Is the ambient temperature used? We are calculating the control valves for the loop piping at its startup
When gas is compressed, heat is released; therefore, the ambient temperature cannot be used. Is there a manual? Is there no theoretical value above?
There is a discharge temperature ranging from -56 to 121 degrees Celsius, but according to the data sheet for its control valve, during the hot start cycle in case 1, the outlet temperature is 120 degrees Celsius and the pressure is 118 Kpa (the normal value being 651 KPa)； In case 2, it operates at 50% load, with an outlet temperature of 118.1°C and a pressure of 651 KPa. How is this temperature calculated?
Yeah………… an expert! The issue right now is that I don’t understand how the gas volume during the hot start of a BOG compressor is calculated, as well as the temperature and pressure
