Process and apparatus for producing hydrogen

摘要

In a process for producing hydrogen,in particular for the use in a subsequent methanation process, water is electrochemically converted into hydrogen and oxygen, the hydrogen is depleted with electrolyte aerosols, and the electrolyte aerosols are subsequently separated from the hydrogen. The separation of the electrolyte aerosols from the depleted hydrogen is performed in a wet electrostatic precipitator in a hydrogen atmosphere.
