Role of Components Containing in Water on the Formation Corrosion - scale Deposits in Pipelines of Heating Systems

Abstract

In this paper, we propose results of research on the establishment of presence of components in water of the southern cities of the Republic of Kazakhstan such as carbonate hardness, noncarbonate hardness and total hardness, content of free carbonic acid and impurities of different ions of iron (two-and three-valent), sulphate and chlorine ions, pH value. When the research course parameters of heat carrier (water): carbonate hardness, non-carbonate hardness, and the total hardness, content of free carbonic acid ions and HCO 3 -, pH value, content of two and three valence iron ions, sulphate and chloride-ions in water were established, indicators of corrosion were calculatedby the value, which we concluded about the strength of corrosive effect on steel foundation of pipelines.

Substantiation of Electron-Seeking Catalysis of Vanadocene Dichloride Oxidative Breakdown in the Process of Vanadium Backwash from Heavy Karazhanbas Oil field

“…Together with electrochemically activated water, 50% sulfuric acid, prepared in a reactor (2) and 50% nitric acid wee supplied to the main reactor. The reactor is a container, equipped by a heated jacket and mixer (6), driven by an electric motor (7), the rate was regulated by a laboratory autotransformer (8). The heating in the jacket was carried out by a hot water.…”

“…But two absorption bands were found in the area of 1650-1600 cm -1 , which indicates the presence of two conjugated C = C bonds. According to the reference [6][7][8] it could be an indication of vanadocene presents in the samples. Taking into account chloride background of aqueous solution, it must be assumed that the presence of the compound in the form of the dichloride.…”

Nonferrous Materials Extraction from Heavy Oil with Using Electro Activated Water-Salt Solutions

“…Secondly, when burning heavy oil residues as boiler fuels, vanadium pentoxide (V 2 O 5 ) is formed -a very corrosive-active component of ash that causes corrosion of boiler and other equipment. The presence of metals in petroleum coke for metallurgy and the production of graphite products adversely affects the products of these industries 1,2 .…”
