Oil gas, compressed

Blau gas (German: Blaugas) is an artificial illuminating gas that is similar to propane. It is named after its inventor, Hermann Blau of Augsburg, Germany. Rarely used or produced today, it is manufactured by decomposing mineral oils in retorts by heat, and compressing the resulting naphtha until it liquefied. It is transported in liquid condition, and, like LPG, when released returns to a gaseous state Wikipedia
