High Throughput Gas Separation (HTGS)

Description

Porometer

The new High Throughput Gas Separation (HTGS) system is a device designed to run up to 16 different membrane-based separations of variable single and mixed gas feeds simultaneously. Up to 5 gases (O2, CO2, CH4, N2, and H2) can be mixed at a set flow. The on-line analysis option permits screening mixed gas selectivities, in comparison to single gas permeation experiments.

MAIN FEATURES

Fully automated: all parameters are set and the system runs the processes autonomously
Feed and purge lines minimize the ‘dead volume’ between separation and analysis
Control of feed composition, pressure, temperature, and flow rates
Automatic selection of feed or permeate line to be analyzed
Complies with the latest safety standards regarding Cabinet construction
Tubing design
Component selection
Hardware
Software security functions
Gas edit surveillance and according to alarms
CE marked: conformity with valid EU guidelines and directives.

TOTAL PACKAGE

The HTGS is sold as a complete package, including:

Permeation cell module for 16 flat sheet membrane samples: Each sample position is provided with a porous metallic support grid and O-rings to ensure tight sealing
Individual adjust of different sample thickness
Retentate purge system to ensure homogenous feed composition throughout the entire experiment
Optional heating of the module is available
Control devices
Compact gas chromatography (CGC) equipped with two thermal conductivity detectors (TCD), which can analyze gases at ppb level, and three columns: Parabond Q (2 m x 0.32 mm): used as pre-column
Molecular sieve column (5 m x 0.32 mm): for the detection of H2, O2, and N2 at the first TCD
Parabond Q (12 m x 0.32 mm): for the detection of CH4 and CO2 at the second TCD
Integrated software for the measurement setup, mass flow control, measurement of the flux, and triggering of the CGC
Electrical cabinet
A vacuum pump for evacuation of all gases into a fume hood

OPERATING SOFTWARE

LabVIEW™ software for data acquisition and instrument control with an intuitive selection of all analysis parameters
Universally available PLC technology (National Instruments) with its own runtime system
Integrated reporting: easy export of results to Excel, Word and pdf file
Windows compatible
The advanced service menu facilitates diagnosis and service via the Internet

OPTIONAL HOLLOW FIBRE HIGH THROUGHPUT PERMEATION CELL

Each individual hollow fiber sample is placed inside a stainless steel tube and secured by gluing the ends of the fiber to the tube ends.

Each tube assembly can be mounted individually on the bottom part of the standard flat sheet sample holder of the HTGS. The gas flow direction during the experiment is from the inside to the outside of the hollow fiber. The upper part of the tubes is attached to a top plate. A gas reservoir for the feed gas mixture guarantees a uniform composition before it goes through the membrane.

Each individual tube has a permeate collection line that can be directed to either the compact gas chromatograph of the HTGS (for analysis of the composition) or to the permeability measuring line. The gas retentate mixture can also be analyzed.

Maximum operating pressure allowed with the hollow fiber membrane module: 10 bar
The maximum effective length of the individual hollow fibers inside the tube: 120 mm
