Drawbacks Treatment Associated with use of Conventional Corrosion Inhibitors Especially in Combustion of Vanadium-Contaminated Liquid Fuels using Nickel Compounds

A new process where used for the treatment of drawbacks resulting from using conventional corrosion inhibitors in thermal equipment (such as Boilers, Diesels and Turbine engines) that burning vanadium-contaminated fuels. Nickelous compounds were used in this work as a base material for the manufacture of these corrosive inhibitors. Nickel hydroxide salt was used in this new work as a suspension in an aqueous solution or an organic solvent with respect to the treated fuel. The results show that this salt is a good choice used as anticorrosion agent in high temperatures equipment that use burning fuels contaminated with Vanadium.  The new anticorrosion agent must contain (8 - 10) % by weight of Nickel metal and(Ni:V) active weight ratio is (2.25: 1).

New Technique for Enhancing the Anodes Performance of Cathodic Protection Deep Well Systems

A special round-grain construction was suggested   for use as a grout material surrounding the anode case of deep well groundbed in an impressed current cathodic protection systems. The experimental results show that the proposed grout material is relatively uncrushable to protect the anode groundbed from collapsing of the wells to undermine, having a good electrical conductivity (low resistivity) which increase the active size of anode, provide a lower electrical resistance to surrounding earth and reduce anode consumption resulting from current discharge. The proposed round-grain shape includes a mixture of different percentage weights of Carbon black powder, Portland cement, Graphite and Surfactant material by mixing (1.8) kg of grout powder with (1) liter of water (mixing ratio 1.8:1) which may be pumped between the groundbed steel casing and soil bore well for a substantial distance up from minimal of the well and in the vicinity of the casing and ultimately to the land surface.
