Question 1

What is OptimEXT?

Accepted Answer

OptimEXT solutions are designed around Sulzer proven extraction technologies, especially around the well-known Kühni™ agitating column. These are combined with Sulzer’s high-performance distillation units to efficiently recover and recycle solvents, transforming challenges into opportunities.

Question 2

What industries and applications is OptimEXT suitable for?

Accepted Answer

OptimEXT is suitable for any facility that includes a liquid-liquid extraction step—or is exploring solvent-based separation to improve process efficiency. Built on Sulzer’s highly efficient Kühni™ column technology, OptimEXT offers exceptional mass transfer performance with low solvent inventory, achieving up to 99.5% recovery efficiency and to ppb-range residue even in challenging feeds.  The system is already proved in many industries:  Refining & Petrochemicals: sulfur, PAHs, BTX, PCA, asphaltenes, phenols  Hydrometallurgy: recovery of cobalt, nickel, rare earths, uranium, copper  Battery & Energy Materials: lithium, manganese, black mass recycling  Wastewater Treatment: recovery of phenolics, amines, sulfonic acids, and carboxylic acids from industrial effluent  Pharmaceuticals & Fine Chemicals: solvent purification, API recovery, impurity removal  Natural Extracts: flavor and fragrance isolation, preservation of heat-sensitive bio-actives  Agrochemicals & Specialty Chemicals: separation of reactive intermediates or solvent recovery  You can explore specific applications under the “Solutions for Your Process Target” section on our website—or contact us directly through optimext@sulzer.com, to evaluate how OptimEXT can be tailored to your operation.

Question 3

How does OptimEXT differ from distillation?

Accepted Answer

While distillation is a widely used separation method, it can be energy-intensive and less effective when dealing with azeotropes, close-boiling mixtures, or heat-sensitive compounds. OptimEXT uses liquid-liquid extraction to overcome these limitations, enabling selective separation at lower temperatures — often with up to 50% energy savings. This not only preserves the integrity of sensitive products but also improves overall process efficiency.  OptimEXT is especially advantageous in situations such as:  Separating azeotropes that cannot be broken by conventional distillation  Handling products that degrade or polymerize at high temperatures  Recovering valuable solvents with lower energy input  Reducing distillation column load and associated operational costs  Improving selectivity in the presence of chemically similar compounds

Question 4

How does OptimEXT compare to mixer-settlers?

Accepted Answer

Mixer-settlers require large footprints and often struggle with process stability at scale. In contrast, OptimEXT uses the Kühni™ agitated column, delivering high recovery efficiency, consistent performance even with variable feed compositions, and a compact, modular design that’s easier to integrate into existing operations. Some proven advantages of OptimEXT are:  Up to 70% lower solvent usage, reducing operational costs.  Compact, modular design cuts footprint by 60%, reducing CAPEX.  Sealed system ensures safer, cleaner operation with minimal emissions.  Stable, high-efficiency performance across variable feed conditions.

Question 5

Why OptimEXT can deliver reliable performance?

Accepted Answer

OptimEXT delivers reliable performance by combining a proven technology platform with decades of in-house expertise in analysis, testing, and design. Its scale-up is supported by technical know-how and real-world data from over 700 systems in operation, ensuring consistent and dependable results across industries.

Question 6

How can I test whether OptimEXT will work for my specific process?

Accepted Answer

We offer both lab and pilot testing options to evaluate OptimEXT for your specific application. Our in-house and rental pilot units are available for flexible deployment, including onsite testing at your facility. When needed, tests can be supported by performance guarantees. Our team will work closely with you to define the testing scope and validate the expected outcomes with confidence.

Question 7

Does OptimEXT include solvent supply or selection support?

Accepted Answer

Yes. In selected cases, we can provide or recommend the appropriate solvent as part of an integrated solution.

Question 8

Who should I contact to discuss my process and get started?

Accepted Answer

You can reach out to your local Sulzer representative, or contact us directly through the email OptimEXT@sulzer.com to schedule a consultation.
