Calculate the propylene oxide specific consumption (PO/SM) for co-oxidation method
Thread Content
CNOOC Shell produces styrene as a by-product of propylene oxide production; does anyone who is familiar with this topic know anything about this process? What was found online is that for every ton of PO consumed, 0.8 tons of propylene and 3.2 tons of ethylbenzene are used, while 2.6 tons of styrene are produced. Why is it that 3.2 tons of ethylbenzene result in only 2.6 tons of styrene?
I don’t know; even those who work at Shell probably wouldn’t know how to explain it
Upstairs, important things really need to be said three times
The selectivity for the dehydration of ethylbenzene to styrene is just a little over 80%. . It may be due to the selectivity of the reactions, as there are several reactions involved: oxidation of ethylbenzene, cyclization of propylene, and dehydration of phenylethanol.
This set of processes relies mainly on foreign technology; it is highly confidential, and few people are aware of it!
