Dehydration unit

Overview
This solvent dehydration system combines conventional distillation with zeolite-based vapor-permeation membrane separation. Designed for the dehydration and recovery of solvents that form azeotropes with water, the unit operates in batch or continuous mode and can achieve dehydration up to 99.9% depending on operating conditions and solvent properties.

Tested solvents

• Ethanol
• n-propanol
• Isopropanol
• Acetonitrile
• n-butanol
• Ethyl acetate
• Tetrahydrofuran (THF)
• Acetone

Features

• Zeolite membrane made of inorganic material, suitable for vapor-permeation dehydration.
• Combination of distillation and vapor permeation improves separation of azeotropic mixtures.
• Membrane modules designed for easy replacement and maintenance.
• Configurable for batch or continuous processing and integration into solvent recovery workflows.
