Abstract
In a method of compressing a gas, a compression which is simple to realize is achieved in that, in a first step, a foam (,) is formed from the gas and a liquid, in which foam (,) the sonic velocity is markedly lower than in the gas and in the liquid taken by themselves, in that, in a second step, the foam is directed at supersonic velocity through a nozzle (,) and the gas located in the foam is thereby compressed, and in that, in a third step, the compressed gas and the liquid are separated from one another behind the nozzle (,).
