Performance & Technical Data

The measurement method and the values that matter.

How it measures

Measurement Principle

The planned Model 820TGA platform continuously analyzes conditioned sulfur recovery tail gas for H₂S and SO₂. The analyzer calculates the H₂S-to-SO₂ ratio and can provide an air-demand indication where configured. Final optical detector architecture and validated performance will be stated in the approved product datasheet.

Analysis TimeConfiguration dependent; final performance value to be confirmed
Measurement ParametersHydrogen sulfide (H₂S) and sulfur dioxide (SO₂)
Calculated parametersH₂S-to-SO₂ ratio and air-demand indication where configured
Sample PhaseGas
Primary applicationSulfur recovery unit tail-gas monitoring
Process compatibilityClaus sulfur recovery and associated tail-gas treatment processes
