Xylenes Production

As part of aromatic complexes, aromatics re-arrangement technologies enable to increase xylene and high purity benzene production from other aromatics. Toluene & A9 transalkylation, toluene disproportionation and toluene methylation will be selected depending on context and objectives.

TransPlus℠ - ParamaX® Suite

The TransPlus℠ process is the low-cost, high-conversion solution to eﬀectively upgrade C₉+ heavy aromatics and toluene/benzene to higher-value products (mixed xylenes and high-purity benzene).

TransPlus℠ is capable of handling the largest feed spectrum, from very light feeds with benzene up to heavy ones composed of C₁₀+ aromatics. This presents exceptional opportunities for profit maximization by offering the possibility to valorize C₉+ aromatics to chemicals and transportation fuels or by upgrading benzene to mixed xylenes when economically attractive.

High conversion per pass

Very low aromatic ring loss & highest tolerance to heavy aromatics

Upgrade low aromatics value to petrochemical intermediates

Para-Selective - PxMax℠ - ParamaX® Suite

PxMax℠ process is the industry benchmark selective toluene disproportionation (STDP) process. The STDP enables rearrangement of aromatics to boost the production of benzene & xylenes from toluene. Produced xylenes are significantly enriched in paraxylene.

Ultra high PX selectivity

Significantly reduced paraxylene cost of production

Longest demonstrated catalyst cycle > 15 years

Equilibrium - MTDP-3 - ParamaX® Suite

MTDP-3 is an alternative to PxMax℠. This technology efficiently upgrades toluene into xylenes at equilibrium and on specification benzene. With a higher conversion per pass, it is ideal when no paraxylene separation facilities are foreseen.

Very high conversion per pass

> 20 years successfully operated at multiple licensees' sites
