Acetaldehyde ( C_2H_4O ) is produced by oxidation of ethane (C_2H_6): C_2 H_6 +

Question

Acetaldehyde ( C_2H_4O ) is produced by oxidation of ethane (C_2H_6): C_2 H_6 + O_2 rightarrow CH_3CHO + H_2O Hence air is supplied at 20% excess, two side reactions occur: 2C_2H_6 + 7O_2 rightarrow 4CO_2 + 6H_2O 2CH_3CHO + O_2 rightarrow 2CH_3COOH (acetic acid) a process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO_2. Calculate the Solar composition of the product stream and the fractional selectivity of ethane to acetaldehyde. Assume that air is composed of 70 mol% N_2 and 21 mol% O_2.

Explanation / Answer

Acetaldehyde ( C_2H_4O ) is produced by oxidation of ethane (C_2H_6): C_2 H_6 +
