COMGAZ : High Presure Sampler

Description

Pre-concentration of trace compounds contained in gases for quantitative and isotopic analyses. The invention applies when the gas is conditioned under high pressure. Thanks to a pressure balancing support the device makes it possible to use a sorbent tube which conventionally operates at atmospheric pressure.

Competitive advantages

COMGAZ simplifies and improves the current high pressure and low pressure procedures:

• Improvement of detection limits compared to high-pressure sampling cylinders.
• Simple to ship and operate at the industrial site, easy to send at the analysis site compare to cylinders-type or bubbling solutions.
• Sampling procedure is several times faster than the ones commonly used.

End users

• Operators of transport and gas storage infrastructures
• Oil and gas industries
• Biogas and bio methane producers

How it works

• Pre-concentration on an adsorbent by circulation of gas under pressure.
• Depressurization of the sample for transportation.
• Sampling device usable with analytical equipment designed for atmospheric pressure.

Technology maturity : TRL 5

A prototype has been realized and validated for mercury and BTEX (Benzene, Toluene, Ethylbenzene, Xylenes) in CH4 up to 100 bar.

We are looking for a partner to develop and commercialize this technology
