Sampling LPG (liquified petroleum gas) should be performed in accordance with sampling standards of ISO 3171, ASTM D 4177, API 8.2 and IP 6.2. These standards dictate a number of key design issues and steps that must be considered to ensure a system fully complies with the requirements of the standards.
Jiskoot manufactures a range of products and fully engineered systems for LPG sampling. Every system is designed to correctly handle the liquid gas avoiding pressure drops and the associated ‘flashing-off’ of liquid to gas. Jiskoot products comply with the standards when installed and operated in accordance with the standards and all systems are supplied with a performance warranty that guarantees compliance with the sampling standards. LPG sampling systems can be designed specifically for high-pressure operating environments and sample receivers selected for the elevated RVP liquids.
Both probe sampler and bypass loop system are available for LPG sampling depending on the accuracy and uncertainty required. Bypass or fast loop systems have the lowest measurement uncertainty and highest accuracy. An in-line probe sampler system offers lower accuracy and higher uncertainty at a lower cost. Bypass loop systems offer the option for on-line instruments such as densitometers to be integrated as part of the sampling loop. This creates a combined sampling and analysis package that provides continuous liquid density measurement, which can be fed to a metering system for mass transfers.
Jiskoot sampling systems and products are designed and manufactured drawing on years of experience of liquid and gas hydrocarbon sampling. They offer you the peace of mind that the equipment that you use every day will fully comply with international best practice. Jiskoot systems are simple and reliable to use, easy to maintain and in the event of a dispute provide irrefutable evidence to support your measurement system.
