HSL-203 : A HYDROGEN SULFIDE ANALYZER (MERCAPTANS)

 

Restrictive legislation has been accepted world wide requiring a persistent increase in emission control of toxic substances. To comply with these demanding regulations a reliable, accurate and continuous analytical technique needs to be implemented which can continuously verify the hydrogen sulfide levels in product gas. The process of removing the poisonous gas is costly and therefore it is of benefit to keep the levels just below regulatory values thus optimizing operational costs.

 

Analytical technique

 

Hydrogen sulfide has a unique UV absorbance spectra as shown below, in many cases mercaptans are also present. Therefore, the ability of the diode array to handle multi-components is clearly relevant in this case.

 

In contrast to a filter based instrument, which measures at a few discrete wavelengths, the diode array spectrometer processes the absorbance signal obtained from the complete spectrum by a multi-component method, thus the measurement accuracy is greatly enhanced allowing for a higher quality and more reliable control signal.

 

Sampling System

 

The sampling system comprises of   the valve mechanism necessary to take the sample gases from the inlet connections through the flow cell and back to the outlet connection. The valve mechanism is arranged such that either the sample gases flow through the flow cell or instrument air for blanking or span gas for system verification.  The pressure is continuously measured and the H2S concentration is automatically corrected. All valves are software controlled.
