Is it feasible to use ethylene cracking C9 as feed for the heavy aromatics column in an aromatic complex, with AC9 being separated out as a material for disproportionation? : 1. Disproportionation feedstocks (C7A+C9A), among which C9A is insufficient. 2. The hydrogenation C9 unit of the ethylene gasoline hydrogenation plant is integrated with an aromatic reforming unit (xylene column or heavy aromatic column) to separate C9A for disproportionation. Options such as using unhydrogenated C9 as raw material for resins, and using hydrogenated C9 in catalytic processes to produce gasoline, are not being considered for now. Could I please get some advice from everyone?
Ethylene cracking gasoline must be passed through an aromatic extraction unit to remove non-aromatic compounds and separate benzene and toluene before it can be fed into the aromatic complex.
