LNG dew point issue

2016-12-02View Original

Thread Content

The storage temperature of LNG at atmospheric pressure is -162°C, but after dehydration using molecular sieves, the lowest dew point that can be achieved is -100°C. Wouldn’t this mean that liquid water or solid ice would form during LNG storage? Or is water further removed during the liquefaction of natural gas after acid and water removal treatment?

Why isn’t anyone answering? I kindly ask all fellow sailors to help answer this question. Thank you!

The solubility of water in LNG is around 1 ppm

Some online sources state it to be 0.1PPm; are there any specifications or standards that address this?

You can look up the property data related to the solubility in impure LNG
