Abstract:
One exemplary embodiment can include an aromatic production apparatus. The aromatic production apparatus can include a first fractionation zone, a second fractionation zone, and a third fractionation zone. Generally, the first fractionation zone can provide a stream rich in an aromatic C8− and a stream rich in an aromatic C9, the second fractionation zone can separate at least one of benzene and optionally toluene from a transalkylation zone effluent and provide a feed to the first fractionation zone, and the third fractionation zone can receive the stream rich in the aromatic C8− from the first fractionation zone. An effluent from the third fractionation zone can be directly comprised in a para-xylene-separation zone feed to a para-xylene-separation zone.
