This report reviews current and developing technologies for xylenes production. Cost estimates have been developed for para-xylene production via a number of processes (e.g., EB Isomerization & Dealkylation, TDP & Selective TDP/Crystallization, PxMaxSM/Crystallization, Toluene Alkylation, C9 Transalkylation/Adsorption/Isomerization, Hydrotreating/Reforming) and meta-xylene production via UOP MX Sorbex technology. Commercial end-use applications; global and regional supply/demand/trade forecasts are included.
