Is it possible that refiners could be overlooking some practical solutions to increasing FCC olefins yields, such as in the gas plant/recovery section?

For C3s, propylene splitters are well-established solutions that most units concerned with C3= recovery have likely investigated. For C4s, most units interested in olefin recovery have at least conducted a paper study to determine if a separations solution would be economical. An opportunity for optimisation could be for customers to pay closer attention to ‘lost’ olefins.
A potential opportunity for further recovery efforts could be that of ethylene. Many feel that FCCs do not produce enough C2= for it to be worth recovering. A future shift in product economics could lead to more attention being paid to fuel gas olefinicity.
