Pharmaceutical
separation, end to end.
Pharma processes burn through solvents. We help recover them. Petro Sep's pervaporation and vapor permeation systems separate water from organic solvents, including azeotropic mixtures that distillation cannot break, with materials of construction and documentation appropriate for GMP environments.
What you get
Outcomes our customers see.
Specific to pharmaceutical. Verified on real feeds. The numbers below come from commissioned projects, not data sheets.
- Solvent recovery rate
- 98 to 99.8%
- Independently verified on isopropanol, ethanol, methanol, and acetonitrile feeds.
- Energy vs distillation
- 1/4 to 1/2
- No phase change penalty; pervaporation runs near ambient temperature.
- Azeotropes broken
- EtOH/water, IPA/water, and more
- Selective membranes separate compositions that distillation cannot.
- GMP-ready documentation
- Materials of construction, IQ/OQ/PQ packages, and validation support included.
Applications

Technologies deployed
The right process for the fluid.
We pair technologies, not promote them. The choice depends on the chemistry, the volume, and the existing site infrastructure.
