The relevance of this work is associated with the need to reduce the volume of water used by returning it to the start of the technological process. Thus, the work aims to improve the quality of the recycled water supply to petrochemical and oil refineries, in particular Atyrau Refinery LLP. This article provides data on purification of blowdown water by reverse osmosis method. A pilot reverse osmosis unit with a capacity of 600 l / h has been manufactured and a technological scheme for purification to standards that meet the requirements of make-up water has been developed, as well as a technical task for the design of industrial recycling water supply systems and appropriate recommendations have been provided.

The relevance of this work is of exceptional importance and is widely used in technological processes at most industrial enterprises, including oil refineries. Industrial enterprises of the oil industry are subject to strict controls on environmental protection, water consumption, and the quantity and quality of wastewater discharged. This article presents data on the treatment of recycled water before the clarification section by reverse osmosis using an electromagnetic treatment device. The authors made a pilot reverse osmosis unit with a capacity of 0.370 m3/h, the permeate output (for purified water) was 0.3 m3/h, the concentrate discharge was 0.07 m3/h. The test bench operates in a closed circuit, i.e. the permeate and brine are returned to the original container. The technological scheme of purification to the standards that meet the requirements of makeup water, as well as the technical specification for the design of industrial recycling water supply systems, has been developed.

A technological scheme and technical documentation for the manufacture of a test bench with a purified water capacity of 300 l/h have been developed. Long-term tests were carried out on a test bench, as well as analysis of the quality of the sampled water before purification, with the use of an electromagnetic treatment device and without it. As a result of the tests carried out, it was found that the total salt content after the reverse osmosis unit decreased from 535.5 to 30.0 mg / l, and in water with the use of magnetic water treat- ment – from 535.5 to 12.7. Moreover, the pH in the first case varied from 8.3 to 6.2, in the second – from 8.3 to 6.44. It has been established that the use of magnetic water treatment in desalination before the reverse osmosis unit has a positive result, namely, calcium and magnesium salts do not settle on the reverse osmosis membranes, thereby prolonging the service life of the reverse osmosis membranes.

The possibilities of obtaining new chelating (complexing) ion exchangers based on copolymers of glycidyl methacrylate (GMA), methyl methacrylate (MMA), tripropylene glycol diacrylate (TPGDA), and oxyethylenediphosphonic acid complexone (OEDP) were studied. The optimal synthesis conditions and studied the physicochemical properties of the resin.To assess the acid-base properties of the synthesized polyelectrolytes, potentiometric studies were carried out, it was determined that the new ion exchangers have a medium acid character, and also belong to polyfunctional ion exchangers. The structure of the synthe-sized ion exchangers GMA-TPGDA-MMA: OEDP, GMA-MMA: OEDP was established by IR spectroscopy and elemental analysis. Studied the influence of the ratio of the initial reacting components, temperature and duration of the process on the static exchange capacity of ion exchangers. It was found that an increase in the amount of oxyethylenediphosphonic acid in the initial mixture in the reaction mixture from 1.0 to 3.0 mass parts leads to an increase in the capacity from 4.3 mEq / g to 6.2 mEq / g according to GMA-TPGDA- MMA: HEDP, from 4.8 mEq / g to 6.6 mEq / g according to GMA-MMA: HEDP. The chemical stability of the ion exchan-gers showed that the obtained ion exchangers are quite inert to chemical reagents. The most stable was the cation exchanger based on the ternary copolymer GMA-TPGDA-MMA: HEDP with a mass ratio of 1: 3. The degree of loss of capacity of the ion exchanger, obtained on its basis, does not exceed 9% when treated with solutions of acids, alkalis, and under the action of oxidizing agents, SEC practically does not change.

In this article the data of the purification of water steam condensate of the LLP "Pavlodar Petrochemical Plant" is considered. In the course of research multifunctional ion exchangers for pre-filters synthesized and were studied. A pilot reverse osmosis unit was produced with a capacity of 600 L per hours, and had been tested to clean steam condensate using a "Unit of Electromagnetic Treatment" (UET) and without it. The optimal treatment mode of purification was selected to the separation of the concentrate 0.1 m 3 per hour. It was found that after desalination of water acidity value of pH changed to acidic medium (permeate) or to the basic medium in the concentrate tract, which associated by decreasing or increasing hydrocarbonate ions, accordingly, in permeate and concentrate. It was noted that the using of the UET at the inlet, led to a slight decreasing of the operating pressure inside the reverse osmosis unit, while on the reverse osmosis unit without UET it corresponded to the calculated value. It was established that the membranes used in testing by using the UET practically have no deposits on themselves, and without it they have a noticeable amount of contamination on their surface. Thus, using the UET in the process of reverse osmosis desalination can significantly increase the service life of membranes and maintain their selectivity, and the proposed method allows to achieve the required water purification standards set by the plant.

A multifunctional anion exchanger based on aniline, epichlorohydrin and polyethylene polyamine was synthesized. The composition, structure, and thermal stability were studied using IR spectroscopy, elemental analysis, and thermogravimetric analysis. The process of extracting strontium ions by classical polarography was studied and the dependence of the sorption of strontium (II) ions in static mode was found depending on the acidity of solutions, the concentration of metal ions and the duration of contact of the ionite with the SrCl2 solution. It was found that the resulting ion exchanger has high sorption properties in relation to strontium ions. The scientific novelty of the study is that the sorption dependence on Sr2+ ions synthesized by ionite was studied for the first time. The practical significance of this work is to develop an anion exchanger with increased recovery capacity, which can successfully solve the problems of cleaning process effluents of non-ferrous metallurgy from strontium (II) ions.

In the review article the general trend of development of the oil industry in Kazakhstan is revealed, its characteristic as one of the main economies of the oil-producing countries is given. The literature data on the formation of the oil refining industry and its current state in Kazakhstan are summarized. It is shown that the global trend in this industry is the reduction of proven reserves of light oil and the emergence of alternative energy sources. In this regard, the further development of the oil refining industry is aimed at increasing the depth of oil refining and oil residues. The search for new technologies and catalysts resistant to high sulfur, organometallic, paraffin and other impurities is the main task of the near future. It is shown that oil refineries have the highest level of water consumption, which involves the development and implementation of effective methods of desalination of wastewater in order to reduce their discharge and return part of the water to the process cycle.

Polyfunctional anionit based on aniline, epichlorohydrin, and polyamines were synthesized. The composition and structure of the anion exchanger were studied by IR spectroscopy and elemental analysis. Lead sorption was studied by classical polarography. Dependences on the sorption of lead (II) ions on the solution acidity, concentration of metal ions, and duration the contact of resins with solution Pb(NO3)2 were determined. This anionite exhibits high capacity in sorption of lead ions. The developed sorbents with increased sorption ability can successfully solve problems of removing lead (II) ions from process effluents in nonferrous metallurgy.

Polycondensation of glycidylmethacrylate, acrylonitrile and nitrilotrimethylphosphonic acid (NTPA), oxyethylidene diphosphonic acid (OEDA) complexes gave new complexing chelating ion exchangers with a static exchange capacity of 0.1 N HCl 3.64 and 3.43 mg-eqv / g. The sorption of Sr2+ ions by complex-forming cation exchangers of GMA-AKN-OEDA, GMA-AKN-NTFA was studied by the classical polarography method under static conditions. The sorption of strontium ions under static conditions from a solution of strontium chloride depending on their concentration and pH, as well as the time of their contact with ion exchanger was studied. It was found that they possess high kinetic and sorption characteristics and surpass the known industrial ionites in their absorbing capacity.
