SOLVOSEP

How It Works

SOLVOSEP uses selective membranes that allow preferential permeation of water or specific components based on diffusivity and solubility. The feed passes through the membrane in liquid or vapor phase, and the permeate is removed as vapor under vacuum or sweep conditions. This enables efficient separation of azeotropic and close-boiling mixtures.

Key Features

• Energy-efficient alternative to conventional distillation
• No need for entrainers or additional chemicals
• High selectivity for water and targeted components
• Flexible configurations: hollow fiber, tubular, spiral-wound, flat sheet
• Operates in liquid or vapor phase modes
• Compact, modular, and scalable systems

Applications

Solvent Dehydration

Note

SOLVOSEP replaces energy-intensive distillation with a membrane-driven separation, particularly valuable wherever an azeotrope makes conventional distillation impossible on its own.
