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.Request a Quote
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:
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 uses an ultraviolet-visibile (UV-Vis) spectrophotometer to measure the resultant SO2 concentration. This method is known to be highly resistant to false positives; full-spectrum analysis quickly removes erroneous data using averaging algorithms.
The TSA-100 uses a long-life xenon light source to transmit a signal through the sample fluid in the flow cell. The signal is carried by fiber optic cables from the analyzer to the flow cell, where the chemical mixture of the sample has unique interactions with the light based on its current composition.
Our proprietary ECLIPSE software processes the raw spectral data to provide real-time concentration readings. The operator can easily navigate between views (trendgraph, spectrum, and more) using intuitive touch-screen navigation. You can also configure alarms, data logging, and outputs. Learn more
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.
Note: All performance specifications are subject to the assumption that the sample conditioning system and unit installation are approved by Applied Analytics. For any other arrangement, please inquire directly with Sales.
