APPARATUSES AND METHODS FOR ISOLATING C8 AROMATICS

摘要

Apparatuses and methods are provided for isolating C8 aromatics from hydrocarbon streams. In one embodiment, a method for separating C8 aromatics from a hydrocarbon stream includes introducing the hydrocarbon stream to a fractionation column at a feed point. Further, the method includes fractionating the hydrocarbon stream in the fractionation column. Also, the method includes withdrawing a sidedraw fraction from the fractionation column at a draw point located above the feed point, wherein the sidedraw fraction includes C8 aromatics.
