New generation wave technology of residual oil-stock liquid-phase oxidation process intensification

In recent years the attitude to bituminous production in Russia significantly changed. In particular, scientific and practical need for naphtha sorting especially for bituminous production is proved. It was promoted by BASHNIYA NP technological classifications of naphtha from the point of view of their suitability for road asphalts production according to which highparaffinic resinous and paraffinic low-resinous naphtha are recognized unsuitable for production of improved brands road asphalts on the existing technological schemes. Heavy asphaltic naphtha is considered to be the most suitable. The problem of the Heavy Petroleum Residue (HPR) maximal involvement in processing is very timely under conditions of oil products amplifying competition in the market on one hand, and against the increasing requirements to their quality from the point of environment protection view - on the other. Development of scientifically applied bases and the bitumen production technology, applied to road construction, should be noted. Especially it is timely in connection with the bituminous production problems which recently became aggravated sharply in Russia. Timely task for oil refineries (oil refinery) currently is ever growing involvement of high-paraffinic resinous naphtha, with application of raw materials preliminary activation express methods (acoustic exaltation, rotor hydrodynamic source of mechanical oscillations, wave influence) in production of receiving oil oxidated asphalts of improved quality

Assessment of inhibitive property of sulfur as a filler of polymer materials with a view to reduce technogenic impact on ecology

© National Academy of Sciences of the Republic of Kazakhstan, 2017. According to modern representations bitumen polymer compositions (BPC) are dispersions of polymers with bitumens. The important stage of creation of durable insulating materials is their inhibition in consequence of oxidation processes in conditions of their application. In this connection the most acceptable substance is sulfur-containing compounds, which effectively performs this role. Currently sulfur production is sharply marked from the number of other extractive industries that from the ecological point of view the most important problem is not achievement of sustained development condition by the sulfur production, but solution of problems of safe storage or even disposal of extracted sulfur. As against other extractive industries, which main efforts are focused on the search of more effective methods of production of required component against its decreasing world reserves, leading companies in sulfur industries worried first of all by the search of new ways for safe management by extracted by them resource

Comprehensive analysis of electrochemical and structural-dynamic properties of bitumnious insulating materials

At the current stage the strategic trend of development of the oil and gas industry is increase in the oil conversation depth with the use of relatively new approaches and methods of mining, treatment, transporting and processing of different kinds of hydrocarbons. Along with that, implementation of new processing techniques, improvement of the production performance and quality of the output products, intensification and reconstruction of the existing oil and gas plants depend not only on the structural materials used but also on the right choice of anti-corrosive materials for protection thereof. According to the existing ideas of the most important factors determining anti-corrosive properties of bituminous insulating materials is mechanical insulation of the material from the aggressive media. Since the insulating film consists of the areas of different density with numerous micropores then by the coating contact with water or electrolyte solutions liquid penetration through the film (diffusion) as well as moisture adsorption by active centers of the film binder (swelling) take place. The criterion of insulating capacity is high effective resistance (minor permeability), low capacity (minor swelling) and slow change in the behavior in the time domain. No less important factor determining the protective action of coatings is film adhesion ensuring not only film adhesion to the material but also preventing appearance of a new phase on the at the metal-film border. The film adhesion strength is affected by the internal stresses arising during the process of coating formation and relaxation processes. In order to protect material from corrosion, special substances are introduced in the insulating material that is able either to change kinetics of electrode reactions determining the corrosive process or inhibit it

Development of the Technology of Macromolecular Structuring of Naphtha Crude Residues During Their Oxidation to Produce Bitumen Insulation Materials

Abstract: One of effective methods to improve the properties of special bitumen is their chemical and physical modification. The chemical a proach suggests the oxidative polymerization is related to chain-radical reactions. Therefore, the modifiers which able to participate in the oxidation of crude naphtha residues, by chemical structuring of the segments of paraffinic chains followed by the formation of polycyclic naphtheno-aromatic fragments that contribute to gumming and preventing the crystalline phase of asphaltene formation are required. Analysis of physical-mechanical properties of the bituminous insulating material (BIM) obtained from oxidized tars showed the ambiguity of their assessment, i.e. the differences in the strength properties of the coatings (C) were observed at similar velocities of naphtha residue oxidation. Modification of the properties of oxidized bitumen occurs by alteration of the nucleus size and the solvate shell of a structurally complex unit (CSU), the introduction of a multi-component bifunctional modifier (MBM) that reduces the oxidation duration and improves the physical, mechanical and insulating properties of BIM. Key words: Naphtha crude residues Paraffin-asphalt associates Physical-chemical modification Oxidative polymerization Structurally complex units Nuclear magnetic resonance relaxatio
