EXPERIENCE!
The know-how of more than 60 years empowers Böhmer to build Ball Valves that help customers to realize their projects effi ciently & successfully for the long term.
Fig. 2. Variation of methane number in sea trial
integrate additional measuring technology into an almost finished ship. Te measuring device had to be installed within a few days and the workers on site had to be trained accordingly. Te successful measurements in Fig. 2 show the variations in the methane number. Te transitions between gas from the boil-off phase and from the liquid phase (after evaporation of LNG) are interesting: the boil-off gas with a high methane content has a higher methane number than that from the liquid phase. Since the higher hydrocarbons can condense out in the feed line from the liquid phase, the LNG from this feed line briefly contains an increased proportion of higher hydrocarbons after switching from boil-off gas, resulting in a lower methane number. Measuring the gas quality will be necessary for gas engine manufacturers in the future.
