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 Fisher 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.

Low historical natural gas prices have revitalized ammonia producers by reducing feedstock and fuel costs. Unexpected disturbances, fluctuating supply and demand, throughput limitations, changes in equipment and catalyst capability, and basic control limitations result in ammonia plants that may not operate at their optimum state. Increased profitability of ammonia plants is achieved using advanced process control (APC). APC reduces variability in the process, allowing the plant to run closer to constraints. Increased throughput at lower specific energy consumption and a consistent quality results in increased profit. This presentation provides details on how improved profitability is achieved with APC.

Corrosion impacts both the profitability and safety of the refinery. Sulfur and chlorides are the two common species that bring corrosion and therefore introduce safety issues to the petrochemical industry. For safe and efficient operation, the concentration of these corrosive species must be monitored by fast and reliable methodologies.Crude oil desalting, sour water stripping and amine treatment are the common processes used to remove corrosive species. Ion chromatography is a reliable and efficient technique to measure the concentration of corrosive species in each of these applications. For example, IC can be used to optimize the sour water stripping process by monitoring of sulfur and ammonia species. Additionally, the determination of heat stable salts and degradation products such as bicine by IC helps maintain amine capacity and avoid corrosion.

This webinar provides specific application examples of corrosive species monitoring in crude oil, LPG, sour water stripping and amine treatment. Discover how IC or Combustion IC can be used to meet regulatory requirements, improve productivity and increase process efficiency. Key Learning Objectives 1) Learn how John Powers from SGS leveraged IC to monitor critical corrosion causing compounds 2) Learn how IC and CIC can be used to meet regulatory requirements 3) See application case-studies where IC quickly and reliably analyzes corrosive amine derivatives, heat stable salts, sulfur species and ammonia.
