Phenol and its derivatives are among the most dangerous pollutants entering the environment as part of wastewater from oil refineries and petrochemical plants, as well as pharmaceutical industry and construction materials. In surface water bodies, phenols occur in the form of their derivatives, namely: free phenols, phenolate ions and phenolates. The listed compounds have different degrees of toxicity, forming humus-like compounds as a result of polymerization and condensation reactions. For this reason, the treatment of phenolic wastewater is a very urgent problem in the petrochemical industry due to the high carcinogenicity of these impurities. Deep purification of water effluents is complicated by the fact that none of the known methods of removing phenols can achieve, with relatively acceptable technical and economic indicators, the required degree of purification. In accordance with the guidance document RD 52.24.480-2006 and the "Instructions for the formation and presentation of operational information on extremely high and high levels of surface water pollution, as well as their accidental pollution" (IGCE, Moscow, 2001), when assessing the pollution of natural waters with phenols, in all cases, 0.001 mg/dm3 is used as the MPC.

The features of phenol alkylation by higher alpha-olefins in order to obtain mono-substituted alkylphenols (o-AF and p-AF) using commercial industrial samples of sulfocationites: Hydrolite ZG CD552, ND-102 and the line of catalysts Purolite CT275DR/4503, CT275DR/4883, CT151DR, CT169DR, which belong to macroporous and are in different price categories. A feature of these cationites is a particularly strong matrix of regularly cross-linked divinylbenzene styrene copolymer. The structure of the granules combines the increased rigidity of the polymer mesh with a highly developed surface of the pores for exchange, which provides a large concentration of available exchange groups and high diffusion permeability of the granules. A comparative analysis of the catalytic activity of alkylation catalysts was carried out, which showed that, despite the high activity of all the studied catalysts in the reaction of alkylation of phenol with ethylene oligomers (OE) of the C16-C18 fraction, most of the studied catalysts showed low thermal stability and showed a tendency to rapid mechanical destruction. During the research, optimal technological parameters for each catalyst were established, including temperature and molar ratio of reagents, providing maximum yields of the target monoalkylphenol at the level of 97-98 %.

A comparative evaluation of the experimental and imported additive packages in the composition of API SL/CF engine oil was carried out. It was found that the experimental package of PH-SL additives in the composition of engine oil has a stable colloidal structure, surpasses the imported package in terms of thermal oxidative stability and tendency to varnish formation and is on par with it in terms of tribological characteristics. During the monitoring of qualitative changes in the state of oxidized oils, including using the method of IR-Fourier spectrometry, it was found that oil with an experimental additive package has an advantage in changing the kinematic viscosity of oxidized oil and the degree of activation of detergent additives compared with oil containing an imported additive package. Based on the results of comparative tests on colloidal and operational properties, it was found that the experimental additive package is at the level of an imported analog. The effectiveness of the use of an experimental additive package instead of imported in the compositions of API SL/CF engine oils has been confirmed.

Based on the analysis of the use of the developed additives to reduce the deposition of coke on a metal plate in the process of tar visbreaking, the effectiveness of sulfur-containing and phosphorus-containing reagents was determined. Under laboratory conditions, the influence of sulfur-containing, phosphorus-containing compounds, reagents containing nitrogen and oxygen-containing compounds in their composition on the process of coke deposition on a metal plate during visbreaking was studied. The process of tar coke deposition in the process of visbreaking in the presence of developed passivators, in the amount of 5, 10, 15 ppm, was studied during preliminary treatment of the reactor and metal plate for 24 hours. The study of the process was carried out on a laboratory batch coking unit with appropriate temperature conditions. It is shown that the use of the developed reagents (P-1, P-2, P-3, P-4) in the process of tar visbreaking, it helps to reduce the adhesive ability of the metal to coke deposition, depending on the concentration, during the pre-treatment time of 24 hours.

Today in Russia there is a task of import substitution, the market of lubricant additives sets very high requirements for quality and economic performance. An integral part of the compositions of modern motor oils are detergent-dispersant additives. Specialists must quickly cope with such requests, so it is worth paying special attention to the collection and analysis of previous technologies and discoveries in order to be able to improve them. It is the superalkaline alkylphenol additives that have shown high technological performance in various operating modes for many years, and this is precisely what meets the requirements of today. Also, great attention should be paid to the availability of raw materials. The challenge is to find the optimal production scale synthesis of alkylphenol, as well as a new catalyst, and the production of alkylphenol salts with a selected metal cation that will meet operational requirements.

The article investigates possible options for processing heavy oils entering refineries separately or when they are processed together with the oils of West Siberian deposits according to the bitumen profile. It is shown that the production of demanded unmodified grades of road bitumen PG 64-28 and PG 58-34 according to GOST R 58400.1 in the conditions of weighting of crude oil during the implementation of the ELOU-AVT-6 installation project at Bashneft-Ufaneftekhim, it is possible if measures are taken to compensate for the deficit in paraffin-naphthenic and aromatic compounds. For the production of these PG grades, an increased introduction of the TVG of this installation is required (from 25 to 40 %), however, it will not require the use of the TVG from AVT, which are in demand for oil production, processing mainly oil from West Siberian fields, or plasticizing components from the oil production complex (selective purification extracts).

Derivatives of xanthogenic acids containing amine and hydroxyl groups were synthesized on the basis of epichlorohydrin. The three-component reaction of epichlorohydrin with various potassium alkylxanthogenates and a secondary amine, whereby the secondary amine was taken strictly according to the calculations, was to obtain β-hydroxy-γ-dibutylaminopropyl esters of alkylxanthogenic acids. The structure of β-hydroxy-γ-dibutylaminopropyl esters of alkylxanthogenic acids was confirmed by IR spectroscopy. Alkylxanthogenic acid derivatives have been investigated as additives for transmission oils. All derivatives had effective tribological characteristics, that is, extreme pressure and antiwear properties.An increase in the alkyl radical leads to some change in extreme pressure properties, reducing the scuffing index from 570N to 530N and the critical load from 1260N to 1190 N. The connections were tested in SN-1200 base oil and I-40A industrial oil. In both oils, they showed better efficiency than additives LZ-23k and ABES, especially in terms of antiwear properties. The study of the effect of the test duration on the antiwear properties revealed their better response over a long period of time 6 and 8 hours than the ABES additive.

Based on the analysis of the use of known and developed additives to reduce coke formation in the process of tar visbreaking, sulfur-containing and phosphorus-containing additives were identified. The influence of sulfur-containing, phosphorus-containing compounds, developed reagents containing combined organic and inorganic compounds in their composition, on the process of tar coke formation during visbreaking has been studied. The process of tar coke formation in the process of visbreaking in the presence of DMDS, DMSO, DMS, TPP, TPPO in the amount of 5, 10, 15 ppm was studied; developed inhibitors of coke formation (IK-1, IK-2, IK-3) at a dosage of 5, 10 and 15 ppm. The study of the process was carried out on a laboratory delayed coking unit with appropriate temperature conditions. It has been shown that the use of dimethyl disulfide (DMDS), triphenylphosphine oxide (TPPO), developed reagents (IK-1, IK-2, IK-3) as coke formation inhibitors in the process of tar visbreaking contributes to an increase in the operating time of coils and furnace columns, and also reduce the pressure drop at the inlet and outlet of the furnaces.

It has been shown that the use of dimethyl disulfide (DMDS), triphenylphosphine oxide (TPPO), developed reagents (IK-1, IK-2, IK-3) as coke formation inhibitors in the process of tar visbreaking contributes to an increase in the operating time of coils and furnace columns, and also reduce the pressure drop at the inlet and outlet of the furnaces.","PeriodicalId":23763,"journal":{"name":"World of petroleum products","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77776823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
