How To Remove Dissolved Oxygen From Water | Atlas Scientific
Four common techniques can be used to remove dissolved oxygen (DO) from water, both chemically and mechanically. These techniques include boiling water at 1 atm (atmospheric pressure)…
Dokumentissa kuvattiin mm. typpikuplituksen tehokkuutta isossa mittakaavassa.Metaanikin (tai ehkäpä propaai/butaanikin voisi käydä ?).
Tuo typpi pitäisi kyllä ensin jollain suuttimella hajoittaa paremmin "mikrokupliksi".Käy muuten kukkarolle!
Countercurrent Exchange
Mechanical removal of DO in the oil field involves using an oxygen-free gas such as methane (CH4) to strip the DO from the water via countercurrent contact exchange. Alternatively, if you want to chemically remove DO in the oil field, sulfur dioxide (SO2) or sodium sulfite (Na2SO3) is used because it is economically friendly.Nitrogen Purging/Stripping
Nitrogen purging, also known as nitrogen stripping, is an industrial process that eliminates unwanted gases and other impurities in water using nitrogen gas (N2).This method is the most effective O2 removal method. However, this method can be expensive as large amounts of N2 gas are needed, prompting new ways to reduce the amount of N2 gas in future DO removal.
