Gas Permeation pilot

To evaluate single and mixed gases, Convergence developed customized gas mixing and gas permeation pilot. These pilots can control any gas mixture at user required pressures and flows. Evaporator units (heating up to 300°C) and integrated GC’s for composition analysis are optional. The gas independent Coriolis Mass Flowmeters accurately measures the mass flow of any gas mixture.

Gas permeation pilot and lab scale systems

The Convergence Inspector systems for gas permeation and gas separation are typically used for measuring membrane performance in, for example, natural gas analysis. The system measures/controls constant flows, pressures and permeabilities.

A vacuum system is available to measure ultra-low flows or to measure diffusion through the membrane.

The systems are suitable for H2S and has pressure ranges up to 100 bar. Tracing and heating/cooling options are available for operating in different ranges up to 250 °C.

Optionally, controlled evaporator systems are available to introduce humidity or other vapors in the gas stream.

The gas separation pilots can be delivered including an optional GC that is fully calibrated and automated. Other sensors such as dew point detectors are also available.

The system comes with a 47mm round disc test cell, but will also fit hollow fiber gas separation membrane modules or any other testobject.

The Convergence Inspector Poseidon is available for gas permeation experiments as well as gas separation experiments on membranes. The system is available for single or mixed gases up to 10 gases and allows to:

  • Fit any module or cell, optionally heatable up to 250 °C
  • Perform single gas permeation experiments
  • Perform mixed gas separation experiments
  • Perform flush steps between experiments
  • Repeat test sequences with different inlet gases
  • Repeat test sequences with varying gas mixtures
  • Repeat test sequences with varyting feed pressures
  • A combination of all options above
