Advisory Summary and Introduction to LNG (and LPG)

Part of the SpringerBriefs in Energy book series (BRIEFSENERGY)


If two non-boiling liquids at ambient temperatures are mixed (say diesel and gasoline fuels) the heat of mixing causes the temperature of the mixture to rise; that’s all.

If two LNG liquids with different compositions, or LPG liquids, are mixed at atmospheric pressure, the heat of mixing will create a large volume of boil-off vapour.

This chapter introduces this and other differences between ambient temperature and cryogenic temperature liquid mixtures, which need to be understood by all users.

The chapter begins with a summary of 15 points towards efficient storage, handling and use, together with some recommendations to prevent stratification and unstable evaporation behaviour, including roll-over.

The chapter concludes with a list of definitions of terms used throughout this monograph.
