Challenges

Challenges for H2 measurement in electrolyzers:

  • Moisture in the process gas destroys the devices and falsifies measurements with thermal conductivity if no sample preparation is available
  • Cross-sensitivity compensation or dehumidification of the gas is required
  • Reaction times (t90) should be kept low in the process and require complex sample preparation
  • Some processes receive corrosive gases
  • High operating pressures and process temperatures require additional sample preparation

Advantages Archigas devices

Advantages of the TCD3000 for H2 measurement in electrolyzers:

  • Sensor is not destroyed by contact with condensate.
  • Significant reduction in the cross-sensitivity of the moisture to the measurement signal.
  • Response times of 30 ms
  • Pressures up to 200 bara are permissible. 700 possible on request
  • Corrosion resistance
  • Continuous online quality monitoring up to H2 4.0 (99,99)
  • Process gas temperatures up to 130°C
  • No additional costly sample preparation and bypass required
  • Reasonable price

The hydrogen concentration in natural gas can be determined using the TCD300 SI.

The measurement is based on the principle of thermal conductivity and offers the advantage of being very fast, robust and stable over the long term. This measuring principle is best suited for (quasi-)binary gas mixtures, where only the sample gas and a background gas are present. As long as the background gas consists of one component or several components are in a stable ratio to each other, a very high accuracy of less than 1000 ppm can be expected. The fluctuations of the individual components of the background gas (natural gas) lead to a cross-sensitivity of the measurement.

Therefore, depending on the application, there are two ways of measuring H2 in natural gas in order to meet the high measurement requirements:

  1. The devices are located directly at the mixing node where hydrogen is mixed with natural gas. The measurement is organized in such a way that it is possible to switch between pure natural gas and the mixture in order to bring the background gas to zero.
  2. You know the matrix of possible components of your natural gas. This allows you to obtain an estimate from us as to whether the cross-sensitivity is within your tolerance.

Otherwise, we should expect the following cross-sensitivities:

  • A variation of ±1 vol% N2 leads to ± 700 ppm deviation of the H2 result.
  • A variation of ±1 vol% CO2 leads to a deviation of ± 1200 ppm.
  • FA variation of ±1 vol% O2 leads to ± 600 ppm deviation.

The devices are currently undergoing certification and target market adaptation. Functional prototypes with ATEX certification can be made available for testing purposes from August 2024.
