Comprehensive pilot facilities across key separation technologies
Distillation and absorption
Even for proven technologies like distillation and absorption, pilot testing is strongly recommended to ensure process success in the following scenarios:
-
Mixtures containing impurities or by-components (e.g., salts)
-
Foaming systems or those with solid content
-
Systems with unknown or unmeasurable vapor-liquid equilibrium (VLE)
-
Processes requiring extremely high product purity
-
Sensitive products where color, smell, or taste must be preserved
-
Batch operation is targeted to deal with multiple feedstocks or products
EvapCare™ evaporators
In many cases, it is not possible to accurately predict film evaporation performance from first principles, especially when the products are temperature-sensitive or viscous. Pilot testing are therefore mandatory in the following cases:
-
Examination of flow and wetting behavior to ensure stable film formation
-
Evaluation and optimization of evaporator type for process efficiency
-
Determination of achievable concentrations, often down to ppm levels, to meet product specifications
OptimEXT™ liquid-liquid extractors
Sulzer offers various type of extractors ranging from agitated column extractor to mixer settler due to scale-up complexity and precise process validation, pilot testing are essential in the following scenarios:
-
Systems where dispersion behavior, droplet size, and phase separation are unclear.
-
Evaluation and optimization of extractor type and phase ratio for best performance
-
Process validation and scale-up that require measurement of achievable concentrations.
-
Selection of suitable equipment for reliable and efficient industrial implementation
Excelot™ multipurpose distillation / extraction batch systems
Sulzer Excelot™ multipurpose distillation and extraction technology is designed for high-versatility batch processing. Due to the inherent complexity of variable feedstocks and the need for rapid product changeovers, pilot testing is essential in the following scenarios:
-
Evaluating separation efficiency and phase behavior across diverse product campaigns
-
Optimization of batch cycle times and thermal integration for maximum operational flexibility
-
Validation of product purity and stability for heat-sensitive or high-value fine chemicals
-
Selection of the optimal Excelot™ configuration to ensure seamless scale-up and efficient cleaning protocols
Comprehensive lab facilities for synthesis, characterization, and testing
Determination of physical properties and equilibrium data
Besides online literature research, we deploy our equipment and experience to measure the most realistic data necessary for scale up:
-
Vapor-liquid equilibrium (VLE)
-
Liquid-liquid equilibrium (LLE)
-
Temperature-dependent density, viscosity, and interfacial tension data
-
Impurities information in customer’s real feed
Bench scale tests
To quickly confirm the feasibility of a process solution with very small feed samples, bench scale tests are ideal:
-
Evaporation tests with rotary evaporator or glass thin-film evaporator
-
Extraction test based on single agitated cell or shaking test for dispersion and phase separation measurement
-
Liquid phase reaction in agitated glass reactor
Toll separation services
Almost all the equipment available in our state-of-the-art IntecH can be used, on demand, for toll separation and purification services. This can be especially interesting in the launch phase of new products, when no dedicated plant is available yet at your premises, or to provide test samples for application in your own in-house tests or for hand-over to your end customers.
