Laser NH₃ Analyzer at a Fertilizer Plant

← Back to Chemicals applications

In-situ laser gas analyzer and stainless steel purge panel for NH₃ measurement in a fertilizer process.

NH₃ measurement in fertilizer processes

Ammonia is a basic component of fertilizer production, and its level in gas streams can be monitored for both process and emission reasons. As NH₃ is a sticky gas, delay and loss in long sample lines are a known problem.

The advantage of in-situ laser measurement

Because TDLAS measures directly on the line, it reduces these effects. Installation considerations include:

  • Protecting the optics with a stainless steel purge panel
  • Assessing dust and moisture load
  • Correct optical path and alignment
  • Verification and maintenance access
