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.

Morphylane® - ParamaX® Suite

In extractive distillation, the addition of a selective solvent modifies the vapor pressures of the hydrocarbons in the feed in such a way that paraffinic and naphthenic components can be separated from the aromatics by distillation.

Morphylane® technology is the most cost effective solution for production of high purity benzene and toluene from C₇- aromatics fractions thanks to the recognized superior characteristics of its patented solvent (N-Formylmorpholine).

Arofining® - ParamaX® Suite

Arofining® innovative solution overcomes difficulties found with historical treatments such as Clay treatment, by implementing selective hydrogenation on the full reformate or any individual aromatics fraction depending on specific needs.

It either eliminates the need for activated clay or allows a major increase in clay lifetime. In both cases, it enhances aromatics complex operation and improves end-user revenue compared to non-selective solutions.

Dimersol™-X – C₄ dimerization

Axens’ Dimersol™-X process transforms butenes to octenes that are ultimately used in the manufacture of plasticizers via isononanol (isononyl alcohol), and diisononyl phthalate units.
