Abstract:
Production and refinement of liquefied petroleum gas (LPG) continues to grow in both the US and North America. Corrosion in these refineries remains a great concern, as billions are spent annually on repairs and lost revenue. Halides and sulfur can contribute to corrosion; therefore, their levels are closely monitored to ensure product quality and maintain operation of the refinery. Combustion ion chromatography (CIC) is an excellent technique for measuring these impurities in LPG and is uniquely capable of quantifying each halide and sulfur individually and accurately. A new standard test method, ASTM D7994-17, has recently been approved for measuring total fluorine, chlorine, and sulfur in LPG using CIC. Approval of this method signifies the reliability of the technique and its acceptance by industry. This presentation will discuss this new method, describe instrumentation and calibration, and present results obtained from real-world samples using this technique.
