In partnership with
Welcome back to LNG4U.
Another week, another set of developments shaping the LNG industry, from market insights and price moves to shipping, terminals, offshore projects, and more.
Here’s what caught our attention this week.
🎓 LNGKnowledge
What are the process steps that the Natural Gas NG passes through from the underground well to the LNG ship's tanks as liquid ❓
The Raw feed gas from the underground well is sent to the liquefaction plant 💧 :
Condensate removal 📉 - It is first stripped of condensates.
Acid gas and Mercury removal 📉 - It is then followed by the removal of acides gases Carbon dioxide CO² and Hydrogen sulphide H²S. Carbon dioxide must be removed as it freezes at a temperature above the atmospheric boiling point of LNG -60°C and the toxic compound hydrogen sulphide is removed as it causes atmospheric pollution when being burnt is a fuel.
Dehydration 💭 - Acid gas removal saturates the gas stream with water vapour and this is then removed by the dehydration unit.
Fractionation ⚡ - The gas then passes to a fractionating unit where the NGLs are removed and further split into Propane and Butane.

Liquefaction 💧 - Finally, the main gas flow, now mostly Methane, is liquefied into the end product Liquefied Natural Gas LNG and stored in tanks ready to be loaded into LNG ships.
