ABSTRACT:
Enabling a transalkylation process to handle both C10alkylaromatics and unextracted toluene permits the following improvements to be realized. No longer extracting toluene allows a reformate-splitter column to be eliminated. The extraction unit can be moved to the overhead of a benzene column and integrated together with the transalkylation unit to reduce costs. No longer requiring a rigorous split between C9and C10alkylaromatics allows a heavy aromatics column to be eliminated. Such an enabled transalkylation process requires stabilization of a transalkylation catalyst through the introduction of a metal function. These improvements result in an aromatics complex apparatus with savings on inside battery limits curve costs and an improvement on the return on investment in such a complex.
