Simulation of tributyl phosphate distillation column design

Thread Content

I am currently working with tributyl phosphate (TBP). The main components in the crude product of the reaction are: tributyl phosphate (42%, wt%), butanol (40%, wt%), and hydrogen chloride (18%, wt%); the hydrogen chloride generated as a byproduct is dissolved in butanol. Design requirements: Design a tributyl phosphate separation tower that operates using continuous distillation; the top of the tower is operated under negative pressure, with a condenser and a reboiler installed at the top and bottom of the tower respectively. The crude tributyl phosphate is pumped into the distillation tower using a pump (flow rate: 1 m3/h, temperature: 35 °C). It is required that the butanol content at the bottom of the tower be <0.01% (wt), and the tributyl phosphate content at the top of the tower also be <0.01% (wt). The distilled n-butanol is reused (the lower the hydrogen chloride content, the better). Help, experts: I want to simulate the design of a separation tower
