Hydrodealkylation (HDA)

Axens Thermal Hydrodealkylation (HDA) is a non-catalytic process that achieves nearly theoretical benzene yields. Axens’ proprietary know-how plug-flow reactor minimizes side reactions and results efficient in both yield and energy consumption.

EMTAM℠ - ParamaX® Suite

Paraxylene yield can be increased thanks to the incorporation inexpensive methanol to toluene in the EMTAM℠ process. EMTAM℠ enables unique product slate flexibility from zero to conventional benzene co-production for greatest resilience to changing market conditions.

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.

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.

LPI (Liquid Phase Isomerization) - ParamaX® Suite

Liquid phase isomerization offers unique market performances with excellent savings in CAPEX & OPEX. It is also the technology of choice for isomerization of ethylbenzene-depleted C8 aromatics streams.

Ethyl-Benzene Isomerizing - Oparis® - ParamaX® Suite

Oparis® harnesses chemistry to maximize paraxylene selectivity thanks to ethylbenzene (EB) to xylene isomerization while restoring the xylene equilibrium of paraxylene-depleted raffinate streams.

Ethyl-Benzene Dealkylating - XyMax℠ - ParamaX® Suite

XyMax℠ efficiently converts ethylbenzene (EB) to valuable benzene while restoring xylenes to an equilibrium mixture in paraxylene-depleted raffinate streams.

Eluxyl® - ParamaX® Suite

Eluxyl® technology employs a state of-the-art, simulated counter-current adsorption concept for paraxylene purification and production from a C8 aromatics stream.

Eluxyl® is an innovative technology enabling the end user to capitalize on future process and molecular sieve improvements.

Aromizing™ - ParamaX® Suite

Aromizing™ is Axens' continuous catalyst regeneration (CCR) reforming process expressly designed for aromatics production.

Thanks to an advanced catalyst formulation affording unrivaled BTX aromatics and hydrogen yields, the Aromizing™ technology drives performance of aromatics complex, while offering low investment, low operating costs and an exceptional on-stream factor.

This technology exhibits:

• Side-by-side reactor arrangement
• Continuous Catalyst Regeneration
• Advanced Regenerator: RegenC-2

Sulfolane - ParamaX® Suite

Liquid Liquid Extraction process uses solvent which forms a separate liquid phase. Aromatics are considerably more soluble than non-aromatics in the Sulfolane solvent. This most up-to-date technology has many outstanding features, among which is the ability to design for a wide spectrum of feedstocks along with high BTX recovery, product purity and operating efficiency.
