Need to Design reactor for ethanol decomposition: C_2H5CH(g) rightarrow C_2H4(g)

Question

Need to Design reactor for ethanol decomposition: C_2H5CH(g) rightarrow C_2H4(g) + H_2O(g) to Me reaction Conversion is 97%, the Feed is 100 mole Assuming there is no side reaction, the temperature require for these reaction to take place is 240 degree C, its continues reaction, Assume its isobaric reaction: Find the type of Reactor or these Conditions (with explanation) Calculate the heat of reaction Find the pressure Suited For these Conditions do mass balance the temperature out of the Reactor with detailed steps) do energy balance (with detailed steps) Find the size Reactor (with detailed steps) Find the Cost estimation For this Reactor (with detailed Steps)

Explanation / Answer

a) For Ethanol Decomposition, Variable Pressure Flow Reactor (VPFR) is used.

d) for the reaction with 97% conversion,

C2H5OH = C2H4 + H2O + C2H5OH

initial no. of mols 100 0 0 0

final of mols 0 97 97 3

The mass balance is

To calculate rest of the part of the questions, enthalpies of reactants and products or some other relevent data need to be provided

Components No. of moles (mol) Molecular waight (g/mol) Mass (g) = No.mols*mol. wt Reactant C2H5OH 100 46 4600 Products C2H4 97 28 2716 H2O 97 18 1746 C2H5OH 3 46 138
