PROCESS FOR PRODUCING PARA-XYLENE |
摘要 |
A process for producing a PX-rich product comprises (a) separating a feedstock containing C8 hydrocarbons to produce a C8 hydrocarbons rich stream; (b) separating at least a first portion of the C8 hydrocarbons rich stream to produce a first PX-rich stream and a first PX-depleted stream; (c) isomerizing at least a portion of the first PX-depleted stream to produce a first isomerized stream having a higher PX concentration than the first PX-depleted stream; (d) separating a second portion of the C8 hydrocarbons rich stream and/or at least a portion of the first isomerized stream to produce a second PX-rich stream and a second PX-depleted stream; (e) isomerizing at least a portion of the second PX-depleted stream to produce a second isomerized stream having a higher PX concentration than the second PX-depleted stream; (f) recovering at least a portion of at least one of the first and second PX-rich streams as PX-rich product; and (g) supplying at least a portion of at least one of the first isomerized stream, the second isomerized stream, the first PX-rich stream, and the second PX-rich stream to the separating (a).
