The TSA-100 uses the conventional pyrolysis method for converting all sulfur compounds in the sample to sulfur dioxide. The system uses a high-performance UV-Vis spectrophotometer to measure the resulting SO2 concentration, which correlates to total sulfur.

Note: for applications that require analysis of up to 5 known sulfur compounds, we recommend the OMA Process Analyzer as a more practical and affordable solution.

Sulfur compounds--particularly hydrogen sulfide--in natural gas carry with them a host of problems and considerations for both producer and consumer. Sulfur content is known to:

  • Cause pipeline corrosion, jeopardizing distribution networks and necessitating complex maintenance regimens
  • Officially reduce the quality of sales gas; natural gas quality assurance involves monitoring of sulfur content, e.g. at custody transfer points
  • Contribute directly to SO2 emissions from gas-burning plants; SO2 is a widely regulated pollutant and a necessary concern for avoiding fines and fulfilling social responsibility
  • Introduce unpleasant odors to gas-dependent industrial and domestic environments; mercaptans are added to natural gas to make leaks noticeable by smell, but uncontrolled sulfur content turns the odor from useful to intolerable
  • Avoiding these chronic sulfur-related issues requires reliable online monitoring of total sulfur load in gaseous hydrocarbon streams. The only way to verify the efficiency of sulfur removal processes and ensure satisfaction of customer and environmental needs is to proactively analyze stream composition.

The TSA-100 is a fully integrated monitoring solution driven by UV-Vis diode array detection. This solid state instrument is a much more practical than the consumable-laden designs that have historically dominated the market.

The TSA-100 sample conditioning system is designed primarily for controlled combustion of the sample.

Upon entering the TSA-100, the sample is split via tee into a bypass loop and a sample loop. In the sample loop, two mass flow controllers are used to accurately mix the sample with air, ensuring an optimal air/fuel ratio for combustion.

The sample/air mixture flows through a pyrolysis furnace, where all present sulfur compounds are converted to sulfur dioxide:

R-S + R-H + O2 > SO2 + CO2 + H2O

The fully oxidized sample then enters the measurement flow cell where SO2 absorbance is monitored (via fiber optic cables). Finally, the sample exits the system as waste.
