weight of condensate that will fill shell side of reboiler, Ibm boilup, lbm/min latent heat of boiling liquid, pcu/lbm

Design experience with flooded reboilers is limited but indicates that typical time constants are of the order of 2—5 minutes. Simulation studies show that substantial improvement in response speed may be achieved by lead-lag compensations with transfer functions such as:
