Problem Your job is to design a sieve tray column to distill a mixture of benzene, toluene, and ethylbenzene. The feed is a saturated liquid at a flow rate of moleshr Under the operating conditions used, the following data is available for the bottom tray in the column.
Temperature bar
Liquid flow rate kmo
Vapor flow rate kmo
Liquid Data:
Mass flow rate
Liquid density
Surface tension
Viscosity
Vapor Data:
Mass flow rate
Vapor density
Use and a tray spacing of inches. You can assume the column operates at of flooding. Calculate the following based on conditions at the bottom of the column.
a
b Uflood
c Anet
d diameter of the column before and after rounding
Report the diameter in units of feet and round up diameter to nearest half foot. Be careful with units. Remember that
Problem Repeat Problem except determine the diameter of a packed column that has a vapor flow rate that is at of flooding. Use plastic Flexirings for packing. Report the diameter in units of feet and round up diameter to nearest half foot. Show the values of flooding, Area, and the diameter of the column before and after rounding. For use the density of saturated water at the same temperature assume pressure has little effect on density
