Process / Technology / Feedstock

Paraxylene is separated out from the mixed xylene stream. In conven-tional paraxylene technology, isomerisation of mixed xylenes takes place through crystallisation or adsorptive separation. Alternative technologies include toluene disproportionation, which yields paraxy-lene and benzene co-product. The BP-UOP Cyclar process, in which propane and butane are converted to paraxylene and benzene, has been used in Saudi Arabia. Paraxylene is a colourless, flammable liquid with a sweet odour.
