“…The indicated inhibitors are well combined with the bituminous-polymerous base, enhancing its protective effect. The inhibitor from the class of QAS for 17G1S-U steel impeded growth of SRB bacteria almost completely showing a high degree of metal protection (95.74%) from biocorrosion (Polutrenko & Pilyashenko-Novokhatnyi 2013, Polutrenko et al 2018. Inhibitors on the basis of derivatives of dioxodecahydroacridines (Polutrenko 2012), which are known to have A determination of areas of biocorrosion development on the route of a main gas pipeline in the Western region of Ukraine antimicrobial and antifungal activity, were also used in the work.…”

A determination of soil corrosivity on three sections of a main gas pipeline in the Western region of Ukraine has been carried out. We have distinguished areas of development of biocorrosive processes with the participation of sulphate-reducing bacteria (SRB). Soil evaluation by the degree of corrosivity has been conducted. We used weight, titrimetric, gravimetric methods, pH-metry, ten-fold limit dilution method and Postgate nutrient medium B for culturing SRB. It has been established that the soil in the first area selected along the lower generatrix of the main gas pipeline has a high degree of corrosivity. It was ascertained that corrosive metal damage increases in the “ferrozone” with the growth of metal exposition time from 24 to 72 hours. The soil selected in the middle part and from above the pipeline refers to soils with a normal degree of corrosive activity. Innovative biostable insulating coatings based on bituminous-polymerous mastic MBPID-1 have been developed, modified with organic inhibitors from the class of quaternary ammonium salts and amines. Regularities of influence of nature of nitrogen-containing corrosion inhibitors of industrial production M, N, L, H and K on the corrosion rate of 17G1S steel for 180 days have been established. It was found that the corrosion rate of steel specimens remained unchanged throughout the study in variants with the presence of inhibitors H and K in the test systems, which indicated their bioresistance to the effect of SRB bacteria.

“…The disadvantages of this method are the uneven distribution of the emulsion on a glass slide and the difficulty of preparing a drug of a strictly known area. 15 -Method for determining the presence of microorganisms by estimating changes in certain fuel parameters (aqueous phase pH, acidity, sulfide content, component composition, metal content, changes in flash point, viscosity, and acidity). This method gives inaccurate information due to the indirect determination of the presence of microorganisms.…”

The current problem of the production and processing of heavy high-viscosity oils in Ukraine and the world has been considered. It has been established that the main reserves of heavy high-viscosity crude oils in the world are located in South and North America, in the Middle East, as well as in Ukraine in the eastern regions. An analysis of various classifications of heavy high-viscosity oils, which are used both in Ukraine and in the world, was carried out. The main extraction methods of heavy high-viscosity oils were considered, in particular, quarry, mine, and well extraction methods. An overview of the technological processes of heavy high-viscosity oil processing was carried out.

There have been revealed and summarized the regularities in biocorrosion of steel 17G1S-U, which is traditionally used for manufacturing oil and gas mains. The basic regularities of biocorrosion processes in the 17G1S-U pipe steel under the influence of SRB Desulfovibrio Sp. strains Kyiv-10 was obtained by weight-loss testing and surface analysis techniques. Effective inhibitors are proposed, which allow protecting steel 17G1S-U against the development of anaerobic corrosion under the influence of sulfate-reducing bacteria (SRB). The effectiveness of inhibitors is estimated by the degree of their protective effect. The porous structure of the surface film contributes to the initiation of localized corrosion. Damage analysis of the specimen surface corroded under different test conditions was performed.
