Engineering >> Chemical & Biomedical EngineeringThe Volume and Conversions of n-Butanol Reactorsby Mariah Greer-Short
Submitted : Fall 2020
The volume (dm^3) of 3 continuous n-butanol reactors (two continuous stirred tank reactors (CSTR) and one plug glow reactor (PFR)) and the amount the kmol/hr of reacted and non-reacted n-butanol. For the first CSTR reactor the volume is calculated by multiplying the original molar flow rate by the percent reacted n-butanol after the first reactions and then dividing by the rate of reaction for that reactor. The 2nd CSTR (last reactor overall) follows a similar process except the original molar flow rate is multiplied by the difference between percent of reacted n-butanol in last reactor and the percent of reacted n-butanol in the 2nd reactor. With an initial molar flow rate of 120 kmol/hr these calculations a produced a volume of 192.8 dm^3 in the 1st CSTR reactor and a volume of 185.7 dm^3 in the 2nd CSTR reactor. The PFR (2nd reactor) reactors volume was found by integrating the initial molar flow rate over the rate of reaction between the 0.2 and 0.6(percent of reacted material from the 1st CSTR to the PFR reactor). The same volume, 901.1 dm^3, could also found by using Simpson’s 1/3 rule.
