Abstract
Processes and apparatuses for para-xylene separation. A stream of para-xylene is separated from a toluene stream in a fractionation column. An overhead stream of the fractionation column is compressed and then passed to a heat recovery zone to transfer heat from the overhead stream to another process stream in, for example, a heat exchanger. The fractionation column may be separating an effluent from a toluene methylation reactor.
