Speciated Sulfur in Natural Gas Pipeline

SulfurChromeâ„¢ GC for Speciated Sulfur

Measures speciated sulfur in natural gas.

Do you need to monitor odorant levels in hydrocarbons? That requires high-sensitivity detection and measurement of the individual sulfur components. Some natural gas pipeline custody-transfer applications also require detailed reporting of sulfur and its various components. Galvanic’s SulfurChrome online gas chromatograph makes it easy, enabling simultaneous, real-time measurement of all sulfur compounds down to the 5 ppb level.

Due to the reactive nature of sulfur compounds, calibration standards containing multiple sulfur components are normally unstable. However, this problem is eliminated with the SulfurChrome analyzer. Its equal and selective response allows the standard to be made up with a single least reactive sulfur component in an inert background gas such as nitrogen. Sulfur separations can be made isothermally out to C4 mercaptans in fewer than 10 minutes. Standard outputs are 4-20 ma. Modbus communication is available.
