Higher accuracy and lower cost LNG
sampling system
Jiskoot has engineered its new high-accuracy IsoFraction LNG automatic sampling system to eliminate the performance limitations and uncertainties of traditional LNG sampling and GC feed systems
The new unit also reduces the costs and operating complexities of alternative ISO 8943 compliant technologies The IsoFraction system allows operators to achieve an accuracy of better than +/-0.15%, thus overcoming the low accuracy problem associated with the existing systems

The right controller for 2-stream blending
The Jiskoot InSpec Blender Controller is a new 3-term PID controller, launched to provide a cost-effective yet powerful and flexible solution for two-stream controlled rate or 'wildstream' blending
Customers using these systems have reported errors of 2% and more, this inaccuracy can cause significant potential losses.
Considerably less complex than alternative technologies, it is also less prone to operator errors and requires significantly less maintenance, reducing a main operating cost as well as installation costs.
Fully complying with the ISO 8943 (2007) sampling standard and the API 14.1 gas sampling standard, the IsoFraction sampling system has fully automatic operation that eliminates the need for manual operator set-up and manual intervention at the end of a batch to extract the samples, which can cause errors in sample representivity.
The system starts and stops immediately in line with the loading or unloading cycle, which ensures that the sample is fully representative of the batch.
Unaffected by changes in line pressure or flow, it can be used in applications where unloading pressure varies significantly or where flow rate changes during LNG custody transfer.
Systems can be fully integrated with gas chromatographs, supplying any online GC device with a representative feed.
They use Jiskoot grab samplers and 3 constant pressure cylinders (CPCs) to ensure an accurate sample is produced, suitable for custody transfer.
