How do they extract natural gases?

It may be possible for me to understand the extraction of natural gases in our modern days, by using such a cutting edge technology, but what I don’t understand is how they did it back in the 1800′? It is not like they could just go in a pit and catch the gases with a jar… Or could they?

There is a difference between Methane, the natural gas in the pipes that your stove uses, and all the other gases – which are also naturally gases.

Methane is found underground with oil deposits, it;s what causes a “gusher”. You drill a hole into the Earth, and cap it with a valve and pipe. The refining process also produces more methane, and all that goes into the pipe.

Other gases, like Oxygen or Nitrogen, are extracted from the air through distillation. Instead of heating a liquid, the air is cooled. Different gases condense at different temperatures, and can be separated that way.
