Hi, I'm dealing with a fired heater data sheet and I'm stuck with the table showing temperature and pressure varying properties: what "Crit Temp - TC" and "Crit Press - PC" are referring to in this table? My only understanding is that I'm not dealing with a pure substance, having a single couple of pressure and temperature values in the p-T phase diagram when liquid and vapour phases coexist: could anyone please help me?
