TOL/A9+ ENERGY EFFICIENT FRACTIONATION PROCESS FOR SEPARATING THE REACTOR EFFLUENT FROM TOL/A9+ TRANSLAKYLATION PROCESSES

摘要

Processes and apparatus for energy efficient separation of effluents from TOL / A9 + transalkylation reactors are disclosed. The apparatus comprises: 1) an overhead stream comprising unreacted toluene, 2) a stream comprising unreacted C9 + aromatics, a portion of the stream may be recycled to the reactor, and 3) the recovery of the para-xylene product And a side draw tower, which produces a side draw stream comprising C8 aromatics that may be directed to the crystallization or selective adsorption para-xylene separation unit for RTI ID = 0.0 a / RTI
