Productized platform
AZEO-SEP®
AZEO-SEP® dehydrates ethanol, isopropanol, and other organic solvents past the azeotropes that conventional distillation cannot break. Where alternatives need an entrainer (benzene, cyclohexane), a third column, and the storage and disposal that comes with them, AZEO-SEP® uses pervaporation membranes selected for the specific solvent. The result is fuel-grade, pharma-grade, or chemical-grade purity in a compact skid.
AZEO-SEP® delivers
What the platform delivers.
Productized does not mean compromised. AZEO-SEP® was tuned to the applications that asked for it most.
- Final solvent purity
- 99.5 wt%
- In most applications. Achievable on alcohols such as ethanol, IPA, and methanol, past water azeotropes such as ethanol/water (95.6%) and IPA/water.
- Payback, alcohol dehydration
- <1 year
- On pure alcohol dehydration plants.
- Payback, hybrid solvent plant
- 2 to 3 years
- For hybrid configurations integrating AZEO-SEP with distillation or AQUA-SEP.

Built on
Pervaporation.
Selective separation of liquid mixtures, including the azeotropes that distillation cannot break.
AZEO-SEP® is the productized application of our pervaporation technology. The technology page is where engineers go for the working principle, full specs, and how it compares to alternatives.
Why this matters to a buyer
- The system is the same platform we already ship at scale; no first-of-a-kind risk.
- If a custom configuration is needed beyond the standard envelope, we engineer it on the same platform.
