You could run a parametric study to check the effect of temperature on separation by a single flash.

propylene = -47.6 C
propane = -42 C
benzene = 80.1 C
cumene = 152.4 C
DIPB = 204 C
l wanted to vaporise the liquid so that only propane and propylene are condensed and eliminated as vapour in the separator. I then entered 0.0259 as this is the mole flow fraction of pentane and propylene divided by the total stream flow of stream 18. But the heavy components become condensed too, see stream 19.

I then assumed the reaction is in series and computed the conversion thereafter, but using these conversions l could not obtain the required selectivity given in the spec. My question is, is there a way to handle complex reactions in COCO, or assumptions that can be made to be able to handle it since the series reaction failed. if not, if l have inputs and outputs to a reactor is there any unit operation l can use to represent my reactor. Thank you

The paper gives us the conversion, was wondering if this is the overall conversion of propylene consumption in two reactions. Also we are given selectivity, how do l implement selectivity in COCO?
