Significant oil losses in oil-containing wastes and their adverse impact on the region environmental setting bring about the need to develop an oil-containing wastes treatment technology. To tackle this issue, the authors have set an aim of designing a helio device and creating an oil-containing wastes treatment method based on it to extract oil products. Considering a widespread in the composition and properties of potential oil sludge raw materials and their tendency for either formation of stable emulsions or phase separation, we have conducted in-depth modern physical and chemical studies and defined the need to develop a commercial oil-containing wastes purification method. We have designed the device, in which oil product hydrocarbons undergo thermal treatment using solar energy. Following oil-containing wastes purification using solar energy, the particulate load in soil does not exceed 6.65–6.79 % and the absolute molecular weight of hydrocarbons approaches that of bitumen. The developed oil-containing wastes purification method solves an important environmental issue of oil-containing wastes recycling, promotes recovery, and prevents degradation of natural complexes, and reduces soil and water pollution.

The article describes in detail the complex oil-containing waste treatment by applying solar energy. The developed Helio devices are equipped with concentrating elements to extract oil in the purification of dump oil. The questions of practical application of pre-treated oil-contaminated soils and oil sludge to strengthen road surfaces are considered. The results of the experimental study on the production of soil concrete is based on oily dump. The structures of the soil concrete made on the basis of oil-contaminated soils and oil sludge are investigated and relevant proposals are made.

Significant oil losses in oil-containing wastes and their adverse impact on the region’s environmental setting bring about the need to develop an oil-containing wastes treatment technology. To tackle this issue, the authors have set an aim of designing a helio device and creating an oil-containing wastes treatment method based on it to extract oil products. Considering a wide spread in the composition and properties of potential oil sludge raw materials and their tendency for either formation of stable emulsions or phase separation, we have conducted in-depth modern physical and chemical studies and defined the need to develop a commercial oil-containing wastes purification method. We have designed the device, in which oil product hydrocarbons undergo thermal treatment using solar energy without prejudice to their chemical structure. Following oil-containing wastes purification using solar energy, the particulate load in soil does not exceed 6.65-6.79% and the absolute molecular weight of hydrocarbons approaches that of bitumen. The oil-containing wastes purification method developed solves an important environmental issue of oil-containing wastes recycling, promotes recovery and prevents degradation of natural complexes, and reduces soil and water pollution.

The article presents the results of a study on the development of the petrochemical industry, which is part of the structure of the fuel and energy complex of Kazakhstan. The development of the petrochemical industry of the country is carried out through the creation of a petrochemical cluster and the construction of plants for the production of petrochemical products (polyethylene, butadiene, polypropylene, polyethylene terephthalate), which are geographically located in the western region of the country, where the main hydrocarbon reserves are concentrated, large oil and gas production enterprises operate, there are necessary infrastructure facilities. Forecast indicators of the development of petrochemistry, technical and economic characteristics of petrochemical projects are given. Information is presented on the development of the petrochemical cluster and the organization of the production of each petrochemical product separately. The authors carried out forecast calculations for import substitution and export in the implementation of petrochemical development projects in Kazakhstan. The purpose of the article is to conduct a predictive analysis of the development of the petrochemical industry in Kazakhstan, since this branch of the national economy is still at the stage of formation.
