Caffeine is removed in factories using super critical fluid extraction. That uses carbon dioxide under pressure (as a liquid) to pull the caffeine out, which can then be evaporated off.
Caffeine can be extracted in an laboratory by adjusting to the right pH, followed by extraction with an organic solvent like hexane.

How is caffeine extracted from tea using methylene chloride?
Caffeine is extracted from tea using methylene chloride through a process called solvent extraction. Methylene chloride is a solvent that helps separate caffeine from the tea leaves. The tea leaves are soaked in methylene chloride, which dissolves the caffeine. The mixture is then filtered to separate the caffeine from the solvent. Finally, the solvent is evaporated, leaving behind pure caffeine.
