SOLVOSEP
Breaking Azeotropes Without Conventional Distillation
SOLVOSEP is an advanced membrane-based pervaporation system designed for efficient solvent dehydration and azeotrope breaking. Using highly selective zeolite and polymer membranes, it offers a low-energy, reliable alternative to conventional distillation and entrainer-based separation methods.
Pervaporation, Selective Sorption & Molecular Transport
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.

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