Dear Experts,
I'm working to a refinery optimization model, investigating the economics for the introduction of a new Cumene unit (from Benzene and Propylene).
At present stage (screening study) it is not possible to obtain the attention of the Licensors.
Other than this site (https://www.cheresou...mene/?hl=cumene), I've already consulted various sources but the available data appears very very confused.
It seems that the most utilized processes are based on zeolite catalysts, with fixed beds reactors (for alkylation and trans-alkylation); the major Licensors of these technologies (process plus catalytic systems) are Honeywell/UOP and Badger/Exxon: the two alternatives appear quite similar.
There are no reliable data relevant to the following important aspects:
- operating conditions for the two reactors;
- specific quantities of the catalysts;
- yields.
I've started with the following guesses:
- alkylation reactor: 25 barg, 100°C, 100% benzene excess, 95% conversion to cumene, 2% yield of PIBPs;
- transalkylation reactor: 15 barg, 70°C, 50% conversion of PIBPs to cumene;
- no idea of the required catalyst quantities.
I would be very happy if someone could kindly comment/improve the above data on the base of his/her experience and knowledge.
Thanks and kind regards,
gegio
