How OptimEXT™ Revolutionizes Liquid-Liquid Extraction in the Process Industry

Introduction

In today’s process industries from chemicals to petrochemicals, flavors, fragrances, and hydrometallurgy the demand for efficient, reliable, and cost-effective separation technologies is higher than ever. Traditional methods like distillation often fall short when faced with complex mixtures, thermally sensitive components, or the need for high selectivity. Enter Sulzer’s OptimEXT: an advanced solution platform that is redefining what’s possible in liquid-liquid extraction and solvent recovery.

What Makes OptimEXT Unique?

OptimEXT is Sulzer’s comprehensive platform designed for the most demanding extraction and solvent recovery applications. By integrating Sulzer’s cutting-edge extraction technologies—including the renowned Kühni™ agitated columns (ECR), packed columns (ECP), mixer-settlers (EMS), and mixer-settler columns (ECMS)—with state-of-the-art distillation, OptimEXT delivers reliable, high-performance, and cost-effective solutions for diverse industrial needs.

Advanced Liquid-Liquid Extraction Technology

Liquid-liquid extraction is a powerful separation method based on the different solubilities of components in two immiscible or partially miscible liquids. OptimEXT™ leverages this principle using specialized equipment to create optimal conditions for mass transfer, droplet formation, and phase separation ensuring high purities and yields even in the most challenging applications.

Key Benefits for Industrial Users

1. High Selectivity and Flexibility

OptimEXT offers a wide range of extractor types to suit every process need:

• Kühni agitated columns (ECR): Universal and flexible, suitable for varying process parameters and physical properties. Capable of more than 30 theoretical stages in a single column.

• Packed columns (ECP): Ideal for high throughput and challenging physical properties, with minimal moving parts and reliable scale-up.

• Mixer-settlers (EMS/ECMS): Perfect for stage-wise contact, long residence times, and processes requiring batch extraction or pH adjustment.

  
  

2. Reliable Scale-Up and Performance

Sulzer’s decades of engineering expertise, combined with in-house pilot facilities and advanced modeling, ensure that OptimEXT solutions are reliably scaled from lab to industrial plant. This means predictable performance, minimized risks, and faster time-to-market.

3. Cost-Effective, Sustainable Operation

With up to 99% solvent recovery, OptimEXT not only reduces operational costs but also supports sustainability by minimizing waste and emissions. Its modular, compact design allows for easy integration and reduced equipment footprint.

Real-World Applications

OptimEXT is trusted by industry leaders worldwide, with over 700 installations across:

• Chemicals and Petrochemicals: Removal of contaminants, separation of azeotropes, and recovery of valuable components from complex mixtures.

• Flavors and Fragrances: Gentle separation of heat-sensitive compounds and high-purity product recovery.

• Hydrometallurgy: Efficient extraction and purification of metals from electrolytic solutions.

• Wastewater Treatment: Removal of pollutants and recovery of by-products from industrial streams.
