Laser CH₄ Measurement on a Hydrogen Line
← Back to Chemicals applications
ATEX-certified laser gas analyzer and communication infrastructure for CH₄ measurement in hydrogen.
Why methane in hydrogen is monitored
Methane in a hydrogen stream can be monitored as one indicator of purity and production efficiency. Since hydrogen lines fall under hazardous area rules, the instrument's certification and installation matter as much as the measurement.
Points to watch in laser measurement
- ATEX certification suited to the application and area
- Calibration of TDLAS for a hydrogen background
- Effects of pressure and temperature changes on the measurement
- Communication infrastructure for transferring data to the control system
