Sulfur Plant Inlet H2S Acid Gas Analyzer System

For continuous, accurate and reliable determination of the H2S concentration in the sulfur plant inlet acid gas stream, Galvanic's 961-AG analyzer delivers the information.

The Model 961-AG H2S analyzer uses the same state-of-the-art technology as our industry acclaimed tail gas analyzer, the 942-TG. Accuracy, Dynamic Range, Reliability and Low Maintenance are a few of the user-derived benefits.

System Benefits

• Full Spectrum Analysis

• Increased Accuracy

Analytical Methodology

As stated previously, the analytical method employed is ultraviolet absorption spectroscopy. The analytical portion of the system consists of a deuterium source lamp, a measurement (sample) cell, and a spectrophotometer with a CCD array as the ultraviolet light detector. The sample cell is a specific optical path length through which a sample of the acid gas flows. Light from the source is transmitted to the sample cell via a fibre optic cable. After passing through the gas space in the sample cell, it is transmitted to the spectrophotometer by a second fibre optic cable. The CCD array converts the light into electrical signals. These signals represent the intensity of the spectral distribution within the band of interest. The spectral data is acquired from the spectrophotometer by the system computer. The computer calculates the concentration of the H2S.
