Welcome back to LNG4U.
The LNG market keeps moving, and there’s plenty to unpack this week, from price developments and market shifts to shipping, terminals, offshore projects, and the wider industry.
Here’s a look at the stories that stood out this week.

How to liquify the Natural Gas and lower its temperature to -160 °C ❓
To lower the temperature of the Methane gas to its atmospheric boiling point, there are three basic liquefaction processes in current use 👇
1️⃣ Pure Refrigerant Cascade process - In order to reach the low temperature required, three 3 stages are involved, each having its own refrigerant, compressor and heat exchangers. The first cooling stage utilises propane, the second stage utilising ethylene and, finally, a sub cooling stage utilising methane is involved.
📌 The cascade process is used in plants commissioned before 1970.
2️⃣ Mixed Refrigerant process - Whereas with pure refrigerant process (as described above) a series of separate cycles are involved, with the mixed refrigerant process (usually methane, ethane, propane and nitrogen), the entire process is achieved in one cycle.
📌 The equipment is less complex than the pure refrigerant cascade process but power consumption is substantially greater and for this reason its use is not widespread.
3️⃣ Pre cooled Mixed Refrigerant process - this process is generally known as the MCR process Multi Component Refrigerant and is a combination of the pure refrigerant cascade and mixed refrigerant cycles.
📌 It is by far the most common process in use today.
