Custom Catalyst and Solvent Solutions: Tailoring Sulzer’s Technology to Your Unique Process Needs

Introduction: Why Custom Catalyst and Solvent Solutions Are Key to Process Optimization

In today’s refining and petrochemical industries, no two plants face exactly the same challenges. Feedstock variations, process design nuances, product specifications, and environmental regulations all require flexible, optimized approaches. Sulzer’s custom catalyst and solvent solutions provide a vital bridge between standard technology and unique process demands, ensuring that each installation achieves its maximum potential in yield, selectivity, and reliability.

The Need for Customization in Catalysts and Solvents

While off-the-shelf materials can serve basic functions, they may fall short when feed compositions shift or when tighter process control is needed. Custom solutions deliver:

• Adaptation to feedstock impurities and composition differences

• Enhanced catalyst activity and selectivity for cleaner reactions and fewer by-products

• Longer catalyst lifetime, reducing downtime and replacement frequency

• Optimized solvent formulations that improve separation efficiency and reduce solvent losses

• Compatibility with evolving environmental standards and stricter operational targets

  
  

How Sulzer Develops Custom Catalyst and Solvent Solutions

Collaborative Process Development

Sulzer partners closely with clients starting from lab-scale studies through pilot testing, using proprietary knowledge and advanced analytical techniques to:

• Screen and optimize catalyst formulations suited for specific reactions such as xylene isomerization, benzene saturation, or hydrotreating

• Design solvent systems tailored to particular extractive distillation or liquid-liquid extraction processes

• Model reaction pathways and separation efficiency for densifying performance predictions

• Validate formulations and process conditions in pilot plants, ensuring scalability and robustness

  
  

Integrated Engineering Packages

Custom formulations are incorporated into Sulzer’s Basic Engineering Packages (BEP) and technology licenses, creating a seamless equilibrium between materials, process design, and operational control. This integration enables:

• Precise process control and repeatability

• Guaranteed performance and product specifications

• Simplified commissioning and scale-up phases

• Effective troubleshooting and lifecycle support

  
  

Real-World Examples of Custom Solutions

Xylene Isomerization Catalysts

For different mixed xylenes feedstocks, Sulzer develops catalysts with variable acidity and pore structure to maximize paraxylene yields while minimizing unwanted side reactions. These catalysts show superior thermal stability, supporting extended plant runs and reduced catalyst changeouts.

Benzene Saturation Catalysts

Custom hydrogenation catalysts balance activity and selectivity to saturate benzene into cyclohexane efficiently with minimal olefin saturation, preserving octane ratings in gasoline reformate streams. This tailored approach reduces hydrogen consumption and improves energy efficiency.

Solvent Reclamation and Optimization

Sulzer formulates extraction solvents specifically for targeted components—such as aromatic or sulfur compounds—in complex hydrocarbon mixtures. Custom solvent blends improve recovery rates and reduce degradation, backed by recoverable solvent recycle systems designed for continuous operation.

Benefits of Choosing Sulzer Custom Solutions

• Performance Tailored to Your Feed and Process: Avoid generic compromises; optimize every step for your plant’s specifics.

• Reduced Operational Costs: Longer catalyst life, reduced solvent consumption, and less downtime save money.
