Usage
Oil shale gas has served as a substitute for natural gas. In the 19th century and in the beginning of the 20th century oil shale gas was used as illuminating gas. In 1920s, gas plants in Tallinn and Tartu produced oil shale gas as a town gas. Since 1948, Estonian-produced oil shale gas was used in Leningrad and the cities in North Estonia. For this purpose, 276 gas generators were operational in Kohtla-Järve until 1987.
As oil shale gas occurs often as a byproduct of shale oil extraction, depending the processing technology it may be used for heating the pyrolysis process.

Famous quotes containing the word usage:
“Girls who put out are tramps. Girls who don’t are ladies. This is, however, a rather archaic usage of the word. Should one of you boys happen upon a girl who doesn’t put out, do not jump to the conclusion that you have found a lady. What you have probably found is a lesbian.”
—Fran Lebowitz (b. 1951)
“Pythagoras, Locke, Socrates—but pages
Might be filled up, as vainly as before,
With the sad usage of all sorts of sages,
Who in his life-time, each was deemed a bore!
The loftiest minds outrun their tardy ages.”
—George Gordon Noel Byron (1788–1824)
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
