Reboiler heat load calculation
Thread Content
There has always been a question: based on the process parameters, how is the heat load of the reboiler calculated? For example: the bottom temperature of the catalytic distillation column is 130 degrees, and the steam we use has a pressure of 0.8 Mpa and a temperature of 180 degrees.
Hehe, I guess I need to study the principles of chemical engineering too
Since it is a reboiler, there should be one key parameter: that is the vapor flow rate at the bottom of the tower. This is the most important factor; other parameters include the liquid reflux flow rate and the flow rate of the product leaving the bottom of the tower. With these values, it becomes possible to calculate the heat load.
