Design a distillation column for styrene Production

(tars are negligible in calculations)

-calculate dew point & bubble points

-calculate wt% leaving at top and bottom of the column

-calculate the relative volatility of top and bottom values, as well as an average value of each

-calculate number of actual trays ( minimum amount and actual amount)

-calculate reflux ratio(underwood)

-calculate a reflux ration and number of trays that work efficiently

-calculate total height to Column

-calculate the column diameter

-calculate the number of plates at rectifying and stripping section

-calculate plate diameter (after deciding which plate is most efficient

-calculate cost approximation of the column and trays ( give separate amounts and a combined total equipment cost)

IF ANYTHING ELSE REQUIRED THEN PLEASE ASK

The penultimate separation process, the ethylbenzene column is fed from the previously mentioned stream H and fed out of the column into streams, and J. The parameters for this ethylbenzene column in context are 56C at 0.075 bar. The primary use of the ethylbenzene is to remove unreacted ethylbenzene to be reutilised for the purpose of greater efficiency and to meet the required amount of styrene that needs to be produced. Below the relevant streams along with their compositions have been detailed Input Stream H (Fig 1.3) Compound Kmol Ethylbenzene 82.354 Methylbenzene 0.002 Styrene 113.05 Tars/Polymers 2.336 Mole % 42.15 0.00 57.85 0.00 Kg 8729.603 0.234 11757.28 2.336 Mass% 42.61 0.00 57.38 0.01 Output Stream (Fig 1.4) Compound Knol h Ethylbenzene 82.107 Methylbenzene 0.002 Styrene 1.689 Mole % 97.98 0.00 2.02 Kg h 8703.415 0.234 175.742 Mass % 98.02 0.00 1.98 kg h Output Stream ) (Fig 1.5) Compound Kmolh Ethylbenzene 0.247 Styrene 110.965 Tars/Polymers 2.73 Mole % 0.22 97.39 2.39 26.188 11540.39 2.73 Mass % 0.23 99.75 0.02
