# Calculate Molar Flow Rates Of Gases Before And After Reaction

Question

Benzene (C6H6) is converted to cyclohexane (C6H12) by direct reaction with H2. The fresh feed to the process is 260 L/min of C6H6 plus 950 L/min of H2 at 100°C and 150 kPa. The single pass conversion of H2 in the reactor is 48% while the overall conversion of H2 in the process is 75%. The recycle stream contains 90% H2 and the remainder benzene (no cyclohexane). See Figure below.

(a) Determine molar flow rates of H2, C6H6 and C6H12 in the exiting product.

(b) Determine the volumetric flow rates of the components in the product stream if it exits at 100 kPa and 200°C.

(c) Determine the molar flow rate of the recycle stream, and the volumetric flow rate if the recycle stream is at 100°C and 100 kPa.

Summary

The question belongs to Chemical Engineering and it discusses about calculation of molar flow rates of gases before and after reaction and volumetric flow rates of the components at high temperature.

Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
