Determination of the tower top temperature,
Thread Content
The light hydrocarbon separation unit sequentially removes C3, C4, and C5. I would like to ask how the top pressure/temperature of the propane removal tower, the pentane removal tower, and the butane distillation tower are determined?
Professional designers can use computer software for simulation, and tests can be conducted based on the simulation results to determine the final process conditions.
Thank you for your reply. I’m learning *simulation
Cooling is achieved using cooling water; the inlet and outlet temperatures of this cooling water are set at 30 and 40 respectively. The temperature at the top of the tower is 5 to 10 degrees higher than the outlet temperature of the cooling water
The tower top temperature agrees with coffeebean’s explanation. At the same time, this top temperature also raises the issue of the tower operating pressure; that is, once the top temperature is determined, it is possible to determine the bubble point pressure of the vapor at that temperature
Yes, it is based on this temperature, which serves as the bubble point temperature of the vapor at the top of the tower, to determine the corresponding pressure, which then becomes the pressure at the top of the tower, and calculations are carried out using this value
