Abstract

Dušik i helij se izdvajaju iz prirodnog plina kako bi se zadovoljile zadane tržišne specifikacije plina, a izdvojeni dušik se može primjeniti u svrhu povećanja iscrpka nafte. Helij je vrijedan plin zbog svoje široke primjene u industrijske, medicinske i znanstvene svrhe. Za izdvajanje dušika i helija primjenjuje se kriogena destilacija, adsorpcija varijacijama tlaka i membranska separacija. Izbor metode ovisi o normama tržišnog plina i o sastav, volumenu i protoku ulaznog plina u postrojenje za obradu. Postrojenja za obradu prirodnog plina mogu proizvesti samo ekvimolarnu mješavinu helija i dušika. Nakon toga, mješavina dušika i helija ide u dio postrojenja na završno pročišćavanje helija.

Abstract: Nitrogen and helium are separated from natural gas due to gas market specifications. Also, separated nitrogen can be used for enhaced oil recovery. Helium is valuable gas due to it's wide usage in industry, medicine and science. Cryogenic distillation, pressure swing adsorption and membrane separation are used for helium and nitrogen separation. Choice of the method depends on a natural gas standards and composition, volume and flow of a natural gas to treatment unit. Natural gas plants are able to produce equimolar mixture of helium and nitrogen only. Mixture goes through final helium purification unit.
