Features and Benefits
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.
Speciated Sulfur Measurement For Accurate Process Analysis
Due to the reactive nature of sulfur compounds, calibration standards containing multiple sulfur components are normally unstable. This is particularly true at the lower ppm levels. 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. This standard is then available for on-line auto calibration and reference check functions. The system equally easy to operate and maintain, with user-configurable alarms, range, streams, and valve times. Inert silco-steel capillary columns are used for sulfur separation, providing long life and trouble-free operation. 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.
