  reboiler
As a result, 38.7 mole percent of IPA at concentrator top gave the optimum value that minimized the total reboiler heat duties of the three distillation columns.
      
We determined the total reboiler heat duties as an objective function and the concentration of IPA at concentrator top as a manipulated variable.
      
The analysis of the dynamic behavior of the system showed drastic change of esterification reaction rate in the reboiler due to the difference of volatility and component boilup rate of each species.
      
For the recovery of lactic acid, two reactions, esterification and hydrolysis, are involved and hence, an apparatus with two distillation columns was developed and operated in a batch mode to ensure enough residence time in the reboiler and column.
      
Because the fractionation unit of the BTX plant has narrow ranges of boiling point and doesn't have any sidecut and side reboiler, we employed the boiling point estimation method in the modeling and simulation of the unit.

Several schemes of process condensate stripping in Hydrogen Manufacturing Unit(HMU) were analyzed and compared. For the mixed feedstock with temperature lower than the bubble point of the bot-tom condensate, the air stirpping scheme is suitable, or else steam stripping scheme is recommended. For units without proper moderate or low level heat source, it is inadequate to adopt reboiler for heating and stripping.
