“…The density of all compounds planned for synthesis was provisionally (for comparison of the products) assumed to be equal to 0.9 g/cm 3 . The hydrophobicity constants lgP (Hansch π-constants) were calculated using the C. Hansch method [26, Ch.…”

“…It has been established reliably that industrial inhibitors of amidoimidazoline series are characterized by "ageing", i.e., variation in the technical, protective and physicochemical characteristics in the course of time: product stratification, a decrease in solubility in hydrocarbons, and abrupt (sometimes by an order of magnitude) decrease in protective properties [1][2][3][4].…”

“…Reactions resulting in "ageing" are inevitable, since they are determined by the chemical structure of compounds and by conditions of industrial production and storage [1][2][3][4]. Furthermore, the thermal stability of amidoimidazoline inhibitors does not exceed 160-180°C.…”

The relationship between the physicochemical and electronic characteristics of inhibitors that allows one to forecast the efficiency of metal corrosion inhibitors in waterhydrocarbon media is discussed. It has been shown that the main molecular characteristics of aliphatic acid amides obtained from nitrogen-containing compounds with one amino group and an N-methylolcaprolactam ester make it possible to forecast that they should have high efficiency as corrosion inhibitors in hydrocarbon media.

“…Service life until degradation, years Degradation location In order to select a possible material for the cladding layers, we performed industrial tests in the operation mode of oil processing units and laboratory studies of the pitting corrosion resistance of steels belonging to various classes (12Kh18N10T, 10Kh17N13MZT, 08Kh21N6M2T, 08Kh22N6T, and 015Kh18M2B) in electrolyte solutions simulating aqueous corrosion media [2]. It was found that steels containing molybdenum additives, namely 015Kh18M2B ferritic steel, 08Kh21N6M2T austeniticferritic steel, and 10Kh17N13MZT austenitic steel, were most resistant to pitting corrosion in the oil processing operation mode.…”

It has been shown that corrosion damage of equipment at an oil refinery plant as a common organism is determined by the combined effect of the process media at all stages of operation. Corrosion charts of units have been composed. Methods for the protection of oil refinery plant equipment from local and downtime corrosion, issues of material selection for cladding of surfaces of vessels and pipelines, and an up-to-date scheme of inhibitor protection of oil processing units in operation have been discussed and proposed. A new approach to the choice of starting products and reactions for synthesizing versatile inhibitors of atmospheric corrosion is considered. A new versatile fungicide inhibitor, VNKh-L-408, has been synthesized using this approach. The reliability and operating capability of units and various kinds of oil processing equipment depend on strict adherence to the operating regulations and on corrosion factors, on the one hand, and on correct choice of materials during design and on the quality of construction activities, on the other hand. Currently there are three guiding engineering manuals (GEMs) developed by VNIINeftemash in 1978-84 for selection of construction materials during the design and upgrading of the main units at domestic oil refinery plants. These GEMs are mandatory for design companies and oil refinery plants. Unfortunately, they are obsolete to a considerable degree and nearly no attention is paid therein to the local corrosion of structural metals and alloys. They either lack data on the likelihood of pit and ulcerous corrosion, as well as corrosion cracking, or, conversely, contain overrated data. They also lack data on the composition and corrosivity of deposits and steam treatment condensates that play an important role in the initiation and intensification of both general and local corrosion of metals.The majority of oil refinery plants in Russian Federation have been put into operation 35-40 years ago. Therefore, the necessity of equipment upgrading and replacement became extremely urgent due to both expiration of the rated equipment life and a considerable Int. J. Corros. Scale Inhib., 2013, 2, no. 2, 92-101 93 metal corrosion, especially local corrosion. These circumstances require considerable adjustments in the design standards with consideration for the real corrosion problems found during operation of units.However, neither the GEMs nor the available international literature treat an oil refinery plant as a common organism with interconnected units that are operated sequentially: "start → production mode → shutdown (for repair or due to other reasons) → steam treatment → drying → repair → start … etc.", and corrosion damage is determined by the joint effects of the process media at all operation stages.The main reason of intense corrosion damage of equipment in process units during shutdown and repair periods lies in the presence of deposits in vessels and pipelines. The chemical composition of the deposits and the ratio of various compounds therein are dete...
