This study was carried out to investigate the physical properties of Fe-Ni, Co-Ni, Co-Mo and Co-W alloys in the liquid state.Density measurements were made by the maximum bubble pressure method at temperatures between the melting points the molar volume of Co-Mo and Co-W alloys increased with increasing concentrations of Mo and W. On the basis of the coefficients of volume expansion of the alloys and electric resistance, the structures of Fe-Ni and Co-Ni alloys in the liquid state were discussed.
Tank sludge forms and accumulates in oil tanks which are used to store crude oil, heavy oil and half-finished oil when such materials are stored over an extended period of time. Although tank sludge has conventionally been disposed of by incineration, a technology for recycling this material was developed and a solidified fuel was obtained.The solidified fuel is produced by mixing by-products (sludge of coke,carbonized RDF) and industrial waste (inorganic sludge) discharged from industrial complexes with tank sludge at an appropriate blending ratio. This material can be processed into a solidified fuel which has excellent handling and storage characteristics, combustion properties, and economy. KEY WORDS : Tank Sludge, Solidified Fuel,carbonized RDF, Inorganic Sludge, Complete Combustion
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
