Solvent recovery efficiency
Purity of recovered solvent
Years in highly regulated environments
In pharmaceutical manufacturing, the solvents used in synthesis, tablet coating and extraction processes have significant value. Destroying them with a thermal oxidiser is always possible, but in some cases, economically non recommendable.
We recover them by activated carbon adsorption with nitrogen regeneration, purify them by distillation and return them to the process at GMP-compliant purity, ready for direct reuse in production, with full technical documentation for every regulatory audit.logi
Pharmaceutical processes require plants that operate in GMP compliance, in ATEX environments, with full traceability of every operating parameter. Our systems integrate activated carbon adsorption, closed-loop nitrogen regeneration, batch or multi-column distillation and molecular sieve dehydration. Every component is dimensioned to meet the required purity specifications, often exceeding international standards, and to produce the documentation needed for regulatory audits.
Closed-loop nitrogen regeneration. Zero explosion risk, zero emissions during regeneration. Suitable for acetone, IPA, and ethyl acetate.
Batch or multi-column distillation with double-effect heat recovery. Molecular sieves for purity > 99.9% on hydrophilic solvents.
O₂ analysers, LEL sensors, dedicated PLCs and remote supervision. Every parameter is tracked and recorded for GMP documentation.
For non-recoverable solvents or low-concentration streams. Up to 99% abatement, available in the Full Electric version.
In pharmaceuticals, compliance is not only about emissions: it is about the purity of the recovered solvent, the traceability of operating parameters and the ability to demonstrate all of this to a regulatory inspector. Our plants are designed to pass audits and to do so comfortably.
Our patent for closed-loop solvent recovery. Operating costs 40% lower than classic systems, zero CO₂, GMP-compliant purity. Payback under 3 years.
Batch or multi-column distillation with molecular sieve dehydration. We achieve purity > 99.9% on acetone, IPA and ethyl acetate, often exceeding standard GMP requirements.
Every operating parameter, temperature, pressure, O₂ concentration and flow rate, is continuously recorded and made available for the process documentation required audits.
The pharmaceutical sector imposes requirements that go beyond simple emission compliance. The purity of the recovered solvent must be demonstrable, operating parameters must be tracked, and the plant must be qualifiable according to GMP guidelines. We design our systems integrating these requirements from the outset, not as a layer added afterwards. The result is a plant that not only meets the limits but also produces the documentation needed to demonstrate this at every inspection.
Solvents recovered by our plants meet GMP purity specifications for direct reuse in pharmaceutical production, with IQ/OQ qualification documentation available.
All components in contact with flammable solvents are designed and certified for ATEX zones. Nitrogen inerting systems and O₂ analysers integrated into the architecture.
We design to comply with the IED Directive for emissions and support the documentation required inspections at global production sites.
The most frequent questions in the pharmaceutical sector concern recovered solvent purity, GMP documentation and the management of regulatory audits.
With closed-loop nitrogen regeneration, and molecular sieve dehydration and distillation, we achieve purity > 99.9% on acetone. In most cases, the recovered solvent exceeds the GMP specifications required for direct reuse in production.
Every operating parameter, temperature, pressure, O₂ concentration and flow rate, recovered solvent quality, is continuously recorded by the PLC control system. Documentation is structured to support inspections, with a historical data log accessible remotely.
Yes. We provide the technical documentation needed for Installation Qualification (IQ) and Operational Qualification (OQ) phases, and on request, we support the client in the Performance Qualification (PQ) under real process conditions.
The modular design of our plants allows adaptations without structural modifications. For significant changes in mix composition, we analyse the impact on the adsorption, distillation and dehydration phases and propose the necessary updates, often limited to the control software or specific components.
Yes. All components in contact with flammable solvents are designed and certified for the ATEX category appropriate to the site zone. The nitrogen regeneration circuit eliminates explosion risk during the critical phase of solvent desorption from the activated carbon.
