Process Technologies

AdvAmine™

AdvAmine™ solutions rely on a unique and long-term cooperation between:

• TotalEnergies, the initial developer of the AdvAmine™ technology portfolio
• IFP Energies nouvelles, an innovative R&I center
• Axens, a recognized licensor.

The Advamine™ series of processes, designed to be suitable for all applications: gas plants, LNG plants, refineries, shale gas, syngas, etc.., enables to treat any type of feed gas composition and to achieve the most stringent specifications. Process configurations are adapted to operator specific cases with tailor-made solvent composition formulation, using open market chemicals in order to reduce solvent costs.

HySWEET™

HySWEET™ has been developed based on the selection of the most suitable physical solvent for blending with a variety of amines (DEA, MDEA, formulated MDEA).

It enables to maximize mercaptan removal together with the absorption of the acidic species while minimizing the usual drawback of hybrid solvents: an increased hydrocarbon co-adsorption potentially harmful for the downstream Claus unit, treating the recovered acid gas stream.

AdvaMEG®

History:
Originally developed by CCR Ltd, now exclusively licensed by Axens. AdvaMEG® is a pioneer technology with the 1^st worldwide reference (1999, Gulf of Mexico, offshore).

Highlights:
AdvaMEG® benefits are supported by:

• The experience of Axens as a process licensor as well as an engineering company delivering complete skid-mounted processing units, for both onshore and offshore applications.
• Continuous improvement of its current know-how based on operating feedback results from its long-term R&D with IFPEN and close collaboration with key partners.
• Selection of equipment and materials which have proven their reliability and high efficiency and are suitable for motions on floating support.

Onshore and Offshore Project Approach:

• Feasibility Stage
  Analysis of flow assurance study outputs, feasibility, scheme definition and conceptual study to optimize MEG regeneration and reclamation sizing.
• Project Execution
  License supply, basic design, process engineering, detailed engineering, revamping studies, procurement, supply of complete processing units/modular turn-key units.
• Start-up
  Assistance in pre-com/commissioning and start-up phases to secure unit performances. Experts on site to allow smooth transition from licensor to operators.
• Operation
  After sales services and continuous end user support such as training, supply of spare parts, analysis and technical assistance.

Cyclohexane Process

The Axens Cyclohexane process is the industry’s benchmark for the production of high purity Cyclohexane by benzene hydrogenation.

The process is combining two steps:

• A liquid phase hydrogenation, for an optimal control of exothermicity and selectivity at the lowest investment;
• A fixed catalyst bed reactor to meet the most severe Cyclohexane product specifications.

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.
