Separating azeotropic and close-boiling mixtures is a formidable challenge in chemical and pharmaceutical processing, often requiring energy-intensive distillation that risks thermal degradation of sensitive compounds.
Sulzer’s advanced Solvent Extraction & Separation technologies, including the OptimEXT™ platform and innovative membrane solutions, tackle these challenges effectively.
Sulzer employs selective liquid-liquid extraction that minimizes heat input and leverages precise phase separation technologies to achieve high-purity separations without introducing harmful additives.
This is especially critical for heat-sensitive products like pharmaceuticals, flavors, fragrances, and specialty chemicals.
Key technologies enabling energy-efficient separation include:
OptimEXT™ integrated liquid-liquid extraction and solvent recovery
Vapor permeation membranes for continuous azeotrope breaking
Structured packing and coalescers to improve phase separation
Batch and continuous processing options adapted to specific feedstreams
By significantly reducing energy consumption and maintaining product integrity, Sulzer’s solutions help manufacturers improve process sustainability and reduce operational costs while meeting strict purity requirements.
