HTGS
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.
HTGS – Ideal for Measuring
Membrane permeability: single and mixed gas
Membrane selectivity: mixed gas
Physical ageing and plasticisation effects
Long term membrane performance (up to several days)
Main Features
Fully automated: all parameters are set and the system runs the processes autonomously
Feed and purge lines minimise 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 analysed
Complies with the latest safety standards regarding:
– Cabinet construction
– Tubing design
– Component selection
– Hardware
– Software security functions
– Gas edit surveillance and according 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 chromatograph (CGC) equipped with two thermal conductivity detectors (TCD), which can analyse 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 intuitive selection of all analysis parameters
Universally available PLC technology (National Instruments) with own runtime system
Integrated reporting: easy export of results to Excel, Word and pdf file
Windows compatible
Advanced service menu facilitates diagnosis and service via Internet
Optional
OPTIONAL HOLLOW FIBRE HIGH THROUGHPUT PERMEATION CELL
Each individual hollow fibre sample is placed inside a stainless steel tube and secured by gluing the ends of the fibre 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 fibre. 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 analysed.
Maximum operating pressure allowed with the hollow fibre membrane module: 10 bar
Maximum effective length of the individual hollow fibres inside the tube: 120 mm
