Measuring the true water content in liquefied gas is a challenge facing refineries, fracking operations, and natural gas processors. Techniques commonly used today include freeze valve testing and humidity sensors which only provide an overview of the sample’s wetness. Depending on the type of gas, water may have a stronger affinity for either the liquid or the gaseous phase. Since these common methods are limited to measuring only the gaseous phase, it is impossible to get a true, quantitative moisture measurement. 

Karl Fischer technology can be used to measure absolute water content in liquefied gas. A KF Gas Analyzer uses mass-flow technology to quantitatively sample liquid or gas phases in compressed LPGs and perform low-level Karl Fischer titration analysis. Accurate and repeatable moisture detection as low as 5ppm in samples like propane, butane, ethylene, and butene ensures a product that is safe for transport or optimal for use in high-quality chemical and polymer production. 

Key Learning Objectives:
• Learn how Shell uses a KF gas analyzer to understand the effect of moisture on yield and quality of finished products 

• Understand how Karl Fischer titration methods overcome the challenges presented with current moisture detection techniques for the analysis of liquefied petroleum     gases 

• Get an update on developments made within ASTM to help improve commercial regulation and testing for moisture in liquefied petroleum gases
