TSA-100

总硫在线分析仪


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.

监测原理

TSA-100在线分析仪运用紫外、可见光光谱学原理来测量SO2浓度。此方法高度防止误报;全光谱分析通过数学计算快速消除错误数据。

光学结构

TSA-100过程在线分析仪使用长寿命氙灯光源传递信号,通过流通池与样品接触。此信号由光源发出,通过光缆传入流通池,与样品气接触。混合有不同化学物质组成的样品对光有独特的吸收,此光信号传出流通池,通过光缆回到检测仪。

用户界面

AAI 专 有 的 ECLIPSE软件将得到的光谱数据处理成实际的浓度读书。在触摸屏控制器上,分析仪的操作者可以非常容易的在不同的界面(走势图,光谱图,浓度读书等等)切换,并且可以自行的,随时设定调整报警,输出,吹扫清零等等。

安全性能

大多数分析仪将样品直接引到分析仪机箱里进行测量,如果样品有毒,腐蚀性强或易爆那将是非常危险的。TSA-100的设计是独特的:我们将光信号引入到样品中,而不是将样品引入我们的分析仪中。样品仅在流通池中流动,不会与分析仪接触。流通池通过光缆与分析仪链接。

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.
