Amine units are common processes for removing H2S and CO2 from natural gas. Gas leaks from an amine unit are particularly dangerous because they can potentially contain concentrated H2S, which is dangerous to humans at concentrations about 100 PPM. Typical leak points are pump seals, valve packing, flanges and instrumentation tubing.
Spartan represents two different technologies for H2S gas detection. Point detectors for H2S can be either NTMOS technology or electrochemical in nature. They rely on the gas cloud coming into contact with the gas detectors.
Point detectors are reliable detectors and have been used in the oil and gas industry for years. They require calibration, typically even 90 days and H2S sensors can be expected to last 3 to 5 years, depending on the amount of H2S the sensor is exposed to in its life.
The Senscient ELDS 2000 H2S detector is an open path H2S detector that uses laser spectroscopy to detect H2S. It is far more sensitive than any traditional point detector. One benefit of open path technology is that it is more likely to encounter the gas cloud because it covers a larger area than a single point detector. The ELDS 2000 is factory calibrated and never requires field calibration. It also never requires sensor changes and will never false alarm because of the precision of the laser spectroscopy.
