Olefins Removal

An important source of aromatics for petrochemical end-uses originates from high severity, continuous catalyst regeneration (CCR) reformers. The current trend towards high severity operation results in higher concentrations of undesired unsaturated hydrocarbons (diolefins, olefins, styrenes) in the reformate produced. They must be removed from downstream unit feeds and final aromatics products.

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.

Negligible aromatics losses to maximize aromatics product income

High olefins removal system availability

Low cost and seamless integration in aromatics complex
