Oxygen (O2) measurement for electrolyser


Mechatest design for new electrolyser unit a Oxygen (O2) gas measurement solution (also known as O2 in H2 wet gas sensor) that allows for analysis of the wet gas Oxygen (O2) stream in Hydrogen (H2)  composition.

The output of the electrolyser is Hydrogen (H2) and Oxygen (O2) as a gas composition and might be saturated with water vapor. To take in a wet gas a Oxygen (O2) sample is not easy, most sensors for this typical measurement in this acceptable price range are mostly not suitable for wet gasses. 

Based on our experience we designed solution with fallback probe, membrane filtration with liquid blocker, and prevent the Oxygen (O2) sensor from harmfull wet gas and extend lifetime much more.

 

Oxygen (O2) as a by-product from the electrolyser is in a high concentration explosive and dangerous gas, humans and the environment are subjected to high safety risks, the Mechatest Oxygen (O2) measurement solution is suitable for explosion dangerous areas. 

We deliver general purpose model and for explosion proof area Ex SIL-2.

Two pressure options, low pressure up to 10 bar or high pressure model for up to 55 bar.

Oxygen wet gas measurement range 0 – 10 vol. %, 0 – 25 vol. %  (other ranges on request).

 

It can be produced by machines (Oxygen Diffuser, Electrolyzer, Rust Deoxidizer), filtered from Polluted Oxygen by Deodorizers or cooling to liquid form.

Oxygen sample wiki

At standard temperature and pressure, Oxygen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with the molecular formula O2.
Oxygen is one of the lightest gases. Oxygen can be breathed in by humans and animals and exhaled as Carbon Dioxide. Due to the fact that Oxygen is lighter than Carbon Dioxide it will rise above it.  

  • Main hazards: Flammable, Explosive
  • Phase: Gas
  • Density: 1.429 (20 °C) kg/m3
  • Boiling Point: -183 °C
  • Explosive limits: 4 %

Electrolyser Oxygen (O2) Gas Measurement

The major challenge in measuring oxygen samples in wet gas in an electrolyser system is to protect the oxygen sensor and ensure a long service life and high quality measurement.
We have improved our Oxygen sampling systems for gas by:

  • Creating closed loop systems emission free which provide a safe, controlled environment
  • Suitable for high pressure process application
  • Simplifying designs, making the sampling of liquid and gas more efficient
  • Proper discharge of excess liquid or gas prevents unwanted pressure build-up in the system

These modern solutions simply regard the sampling systems themselves. Our worldwide reputation rests on the combination of excellent Oxygen measurement systems, and professional services by our team of specialists.
