Case:
A mixture containing 45% benzene (b) and 55% toluene (t) by massis fed to a distillation column. an overhead stream of 95 wt% b isproduced, and 8% of the benzene fed to the column leaves in thebottom stream, the feed rate is 2000 kg/h.
ENGINEERING MATERIALS
1. Suggest the Suitable Material to fabricatethe Distillation column.
2. Identify the corrosive behavior of chemicalsto the selected material and calculate the corrosion allowances forthickness of the column.
3. Explain the suitable maintenance procedureinvolved in distillation column.
PROCESS CALCULATION
1. Write the hypothesis for the abovedistillation column calculations.
2. Determine the overhead flow rate and themass flow rates of benzene and toluene in the bottom stream.
3. Draw the flowsheet and investigate therequired output streams.
TECHNICAL MATHEMATICS
Draw the graph for Temperature Vs Vapor pressure Benzene andVapor pressure of toluene.
Vapor pressure data of benzene and toluene
Temperature | Benzene (mmHg) | Toluene(mmHg) |
80.1 | 760 | - |
85 | 877 | 345 |
90 | 1016 | 405 |
95 | 1168 | 475 |
100 | 1344 | 557 |
105 | 1532 | 645 |
Assume Feed (F) is directly proportional to theDistillate(3 + 4 = 7 Marks)
                       F=f (D)
f (D)= 4D3 5D2 + 2D + 8.
Determine the interval for which the distillate is increases,decreases and constant.
Show that whether the feed F is max, min or neither. Alsodetermine the possible value of F.
