This sampling process provides improvements over conventional methods due to the high volume of gas flowing through the system which ensures representivity of the gas both sampled, and fed to a GC.
The LNG sampling system will normally employ three gas samplers tied into a single process loop to allow three independent but comparable samples to be taken.
In addition, provision is made to allow the extraction of fixed volume samples to conventional 500ml receivers at key intervals (25/50/75/100 %) of the batch. These are spot samples and require the vessels to be purged to ensure representivity of a specific point in the batch. |
