Aspen Plus

Doing some preliminary chemical reactor simulations. It turns out doing the first trial simulation that the simulation returned no errors. However, it showed that all propylene reacted and there was literally 0.8ish kmol/hr of the undesired product formed. There might have been some miscalculations with converting the pre-exponential factor to the appropriate units for aspen.

Another idea is to actually employ a sensitivity analysis on the reactor plotting temperature vs. reactor volume and pressure vs reactor volume to see the result effects to get some type of idea of an ideal operating range/volume. There is a note that selectivity increases when temperature is lower but that will undoubtedly increase the size of the reactor. There seems to be some what of a balancing act and whatever we choose we have to justify such choices.
