СПОСОБ ОТДЕЛЕНИЯ МИКРОКОМПОНЕНТОВ ОТ БОГАТОГО АЗОТОМ ПОТОКА

摘要

A method for separating hydrogen, helium and/or neon from a nitrogen-rich liquid fraction present at a pressure of at least 10 bar is disclosed. The nitrogen-rich liquid fraction is expanded and undergoes phase separation where expansion takes place at a pressure which allows separation of hydrogen, helium and/or neon except for residues of less than 20 ppmV.
