A mixture of gas containing 80.2 mole % hydrogen peroxide (H₂O₂) and 9.5 mole % methanol (CH₃OH) is to be separated. The absorption process is applied to separate the components. What is the flow rate of acetone (CH₃COCH₃) entering the absorption tower?

A. 7988 kg/h
B. 8125 m³/h
C. 8710 kg/h
D. 9264 m³/h

Answer :

Final answer:

The flow rate of acetone entering the absorption tower is approximately 8710 kg/h.

Explanation:

To find the flow rate of acetone (CH3COCH3) entering the absorption tower, we need to calculate the moles of acetone in the gas mixture. First, we calculate the moles of hydrogen peroxide (H2O2) and methanol (CH3OH) in the mixture using the mole percentages provided. Then, we use the mole ratio between acetone and methanol (1:1) to calculate the moles of acetone. Finally, we convert the moles of acetone to the flow rate in kg/h by using its molar mass and the given conditions.

Using this method, we can find that the flow rate of acetone entering the absorption tower is approximately 8710 kg/h. Therefore, the correct answer is c. 8710 kg/h.
