Technical Support & Performance Management

Axens experienced start-up Advisors will come on site to perform a complete and detailed inspection of the units, associated equipment and P&ID to ensure the construction conformity to Axens original Process Design Package.

Afterward, to get a “Ready for Start-up" meeting all safety compliances, a dedicated team of experts will execute:

• The detailed start-up procedures
• Interlock safety devices review
• Catalysts & adsorbents loading supervision: dense / sock
• Leak tests supervision

Following the commissioning step, operators will proceed to the next phase fully supported by Axens experts: the unit start-up.

Our team is at your service for assisting you during the following steps:

• Catalysts activation
• Fresh feed-in
• Unit tuning and stabilization
• Performance tests

Our goal at the end: your unit is efficiently running at full capacity producing on-spec products.

Key advantages:

• Our team can maintain 24-hour coverage on site
• Specialists and experts thanks to a wide and proven experience
• Worldwide presence close to operators’ site

To optimize the unit’s performances and conduct troubleshooting, Axens provides assistance either regularly or on-request, as well as either remotely or on-site.

Depending on the required assistance, an Axens Tech Services Advisor is dispatched to the site to evaluate the operation and propose a strategy to recover or improve performance providing the following support:

• Support from Axens Headquarters / regional operational center for troubleshooting (hotline)
• Review current operation and recommend optimizations for plant on-stream profitability
• Assist on-site during unit turnaround (inspection, catalyst loading and re-loading & support for unit re-start)
• Routine / specific analyses including spent catalyst and liquid samples analyses
• Provide regular reporting
• Continuous improvement: recommendations for a better unit profitability

Our team will rely on digital tools and software to provide the most accurate recommendations:

• High Fidelity models available in real-time with Connect’In® 
• Model-based predictive control technology with Axens APC algorithm
• Packaged modelling application tuned and validated for refining and petrochemicals units with WebPOS™

Axens provides support for Catalysts & Adsorbents by managing change-outs while meeting cost reduction, targets and deadline with Orchestra™.

Orchestra is a wide and flexible range of integrated services optimizing catalyst and adsorbent change-out phases by:

• Identifying the optimum technical solution in line with operator strategy and constraints,
• Reducing overall turnaround costs,
• Integrating specific needs like catalyst pool management, used products valorization or waste disposal,
• Customizing supply scope, from standard offer to single source turnkey contract,
• Being fully compliant with environmental regulations.

For applications based on non-regenerable adsorbents (AxTrap™ Series) where contamination is an issue, our Sorbotest on-site pilot test is available to help you identify the problem and respond with the appropriate solution. Sorbotest® can be used for both feasibility study and troubleshooting purpose.

Sorbotest is a unique transportable non electrical device using a skid-mounted adsorber that can identify an array of feedstock contaminants.
