Diesel control temperature
Thread Content
I would like to ask the experts: why is it necessary to control diesel using the vapor phase temperature rather than the liquid phase temperature?
Controlling the gas phase temperature of the diesel extraction layer is equivalent to controlling the diesel extraction temperature; it is only within this temperature range that the diesel components can be distilled out.
Can it be understood as a lag in the liquid phase temperature?
I’m not very familiar with the process, but I think what was said on the third floor makes sense: \"Controlling the vapor temperature in the diesel extraction layer is equivalent to controlling the temperature at which diesel is extracted; it is only within this temperature range that the diesel components can be distilled out.\" ”
I’ve learned it – at which point is the vapor phase temperature most accurate? Or they’re more or less the same
Considering the feeding characteristics of the fractionation tower, controlling the 95% point of diesel using the gas phase temperature below the stripping tray is more effective
