Fast and Reliable TS Determination in Liquefied Pressurized Gases (LPG) according to ASTM D6667, ASTM D7551, and DIN EN 17178

Gaseous compounds in the liquefied pressurized state are valuable source materials for chemical synthesis or polymerization, but are also increasingly utilized as energy carrier for heating, power generation and transportation purposes. The concentration of sulfur compounds is a key parameter for their quality and usability. Because sulfur compounds may cause catalyst poisoning and undesirable by-products, their content should be <100 ppb, to avoid increased production costs. For the use as combustible or fuel (LPG, CNG), different requirements and standards apply. Here emission limits for sulfur must not be exceeded and the odorants (e.g., mercaptan) added for safety reasons must be at the appropriate level. To guarantee optimum product quality and instant process optimization, the rapid detection of ultra-low and high sulfur contents is required in LPG analysis
