process overview

Solvent recovery isolates and purifies used solvents from contaminants for reuse. The process leverages different boiling points with distillation as the most common method. For complex mixtures including azeotropes (e.g., IPA-water), we design advanced systems using Extractive, Azeotropic, or Pressure-Swing Distillation. 

Our Goal:

Return solvents at quality often higher than virgin material, consistently achieving >99.9% purity. 

Key Performance Metrics

Proven results that drive operational excellence

Recovery Rate

Up to 99%. Case studies show 94-98% for complex pharmaceutical solvents

Solvent Purity

> 99.9% - ultra-high purity for pharmaceutical -grade reuse ( >99.9 wt% for THF) 

Energy Efficiency

Reduced kWh/kg using smart design, heat exchangers, & vacuum distillation

Payback Period

<2 Years - often as little as one year
