Processes for maximizing high-value aromatics production utilizing stabilized crude benzene withdrawal
Abstract:
Processes for maximizing high-value aromatics production utilizing stabilized crude benzene withdrawal are provided. Aromatic reactor effluent comprising a C5− fraction and a C6 to C10 fraction is separated into a benzene-rich stream and liquid and vapor streams depleted in benzene, one of the liquid streams depleted in benzene being a benzene-depleted C6− fraction. At least a portion of the C5− fraction from the benzene-rich stream is removed.
