Liquefied Natural Gas (LNG) - Bulk

CH4

LNG is produced by the liquefaction of a gaseous natural gas stream. It is filled into T75 cryogenic isocontainers as a liquid or tube skids as a compressed gas for international transport. Skids are approved by DOT, TC, RID / ADR and IMO. Cryogenic containers are approved by UN, RID/ADR, CSC, AAR-600, DOT, TC, TIR, UIC.

Standard Specifications

LNG is sold by its energy value in Mj/Kg. Impurity specifications vary considerably by source. A typical analysis is illustrated below.
