... ABSTRACT Bio-oils derived from biomass contain organic species and acids that can be corrosive to steel-based structural materials used for pipelines and storage tanks. It is, therefore, important to assess corrosivity of organic constituents in bio-oils and identify ferrous alloys...

A mass balance around the water and the constituents helps to determine needs...

... with decrease in FCT. At lower SCT which belong to the austenite-ferrite two-phase region, BF was observed instead of AF. In all steels, the martensite and retained austenite (M/A) constituents were observed and the area fraction of M/A constituents increased with decrease in FCT. ISO17081(2004) standard...

... of these conditions arise. The method of choice for removing large deposit inventories has been chemical cleaning during a refueling outage. Because the chemical cleaning solvents typically used for nuclear steam generators contain various volatile constituents, utilities and vendors performing chemical cleaning...
