Cast iron pump rotor graphitic corrosion

Abstract:

This paper describes a case history of a rotor of a pump made of cast iron. This pump was used for the extraction process of soybean oil by using a solvent (hexane). A graphitic type corrosion was detected which was attributed to the presence of chlorides and moisture in the solvent.
