LINDE/NESTE CORP.Low level oxygen enrichment-field trial experiences and a new Clans unit application

摘要

Air has been used as the oxidant in Claus units since the 1930s,but today there is a clear trend to use at least moderate amounts of supplemental oxygen to enhance operational flexibility and plant reliability.Especially in refineries,applying low-level 02 enrichment(process air containing up to 28 vol-% oxygen)has gained considerable acceptance and importance.
