PRODUCT

pervaporation.

Our lab-scale and pilot-scale pervaporation (PV) systems are designed to evaluate and optimize membrane-based separations driven by osmotic and vapor-phase mechanisms. These systems support a wide range of applications, including:

  • Solvent dehydration (e.g., alcohol/water mixtures)
  • Recovery of organics from aqueous streams
  • Aroma and volatile organic compound (VOC) recovery
  • Hybrid distillation–pervaporation processes

versatile configurations and membrane compatibility

Users can quantify key performance metrics such as permeation flux, separation factor/selectivity, permeate composition, thermal efficiency, and long-term membrane stability under diverse operating conditions.

The system accommodates both hydrophilic and organophilic pervaporation, with optional vapor permeation (VP) configurations for gas-phase feeds. It supports flat-sheet and tubular/ceramic modules, offering flexibility for research and pilot-scale studies across polymeric and ceramic membrane types.

demcon-convergence-pervaporation

fully customizable system

The system can be tailored to meet the specific requirements of your pervaporation project, with options including:

  • High-temperature and deep-vacuum capability for enhanced driving force and distillate recovery.
  • Materials compatibility for aggressive solvents and chemicals (e.g., stainless steel or Hastelloy wetted parts, PTFE/PFA-lined tubing).
  • Advanced sensing integration, including inline refractive index, density, conductivity (for aqueous phases), pH, permeate-side vacuum/pressure, and mass measurement for real-time flux and separation factor calculations.
  • Automation features, such as recipe-based control, setpoint ramps and soaks, alarms/interlocks, and comprehensive data export for post-experiment analysis.

Advanced Control and Automation

Our intuitive software interface enables precise monitoring and control, automatically recording essential parameters including temperature, pressure, flow rate, vacuum level, and permeate mass or volume. Users can create and automate custom experimental scripts, making it ideal for:

  • Rapid performance screening
  • Long-term fouling, swelling, and aging studies
  • Temperature and driving-force sweeps
  • Steady-state mapping

Full automation and robust data logging ensure reproducibility and accurate analysis.
