Research of the gas generation process during the thermolysis of high-sulphur petroleum feed
Keywords: High-sulphur fuel oil, thermolysis regimes, decomposition gas composition, mass values of gas output for 1 minute, velocity constant, activation energy.
Abstract. The carried out research of thermolysis process of high-sulphur fuel oil with gas sampling and compositional analysis of feed decomposition gas allowed to establish two regimes of gas generation within the range of 380–400°С and within the range of 400–450°С. The first range is characterized with higher content of hydrogen sulphide in gas. The second range is characterized with higher content of hydrocarbons С1С2- and sufficient decrease of hydrogen sulphide content. On the basis
of the results of the research the velocity constants have been calculated and the assessment of the values of activation energy of the thermolysis process for the given temperature ranges has been made. There are presented the data on the output of decomposition gas within wide temperature range of fuel oil heating.

Сombined clean diesel oil fraction: pre-ozonation and hydrotreating
Keywords: total sulfur, ozonation, oxidation, hydrotreating.
Abstract. Stricter environmental requirements to oil and oil products, including sulfur – modern requirement of the world market, caused by the need for regulatory compliance in commercial products environmental standards. The article describes the technology of removing sulfur containing compounds from the diesel fraction of oil by combining the traditional method of Hydrotreating with advanced oxidative effects of diesel fraction of ozone and the subsequent extraction of the obtained compounds.
The purpose of this blending is the destruction of thiophenic sulfur compounds from the diesel fraction of oil which are not removed in the Hydrotreating process and the allocation of these compounds for further use in the chemical, petrochemical and metallurgical industries. The article deals with the methodology of the combined clean diesel oil fraction with application of Hydrotreating and pre-ozonation of raw materials and the optimum conditions for carrying out this process. As a result of researches it is established that the combination of a Hydrotreating process with pre-ozonation reduces the final total sulfur content in the diesel fraction more than 2 times compared to traditional Hydrotreating process.

Mathematical modeling and optimization of dehydration and desalting processes for heavy oils
Keywords: mathematical modeling, heavy high viscosity oils, fractional factorial design (FFD), response surface methodology (RSM), dehydration and desalting rate, optimal process parameters.
Abstract. The heavy and high viscosity oil production often leads to the formation of water-oil emulsions with abnormally high aggregative stability. The preparation of such oils for processing on electric desalting plants (ELOU) atrefineries requires the use of specialtechnological solutions for the destruction ofpersistent water-oil emulsions. In this work, based on the Yaregskaya oil (density0.940g/cm3at 20°C) basicprinciples of modeling of dehydration and desalting process were illustratedfor heavy high-viscosity oils. Investigation of basicfactors effect on the efficiency of dehydration and
desalting processes was carried outon a pilot ELOU plant.Mathematical modeling of the ELOU plant was carried out using Fractional Factorial Design (FFD) and Response Surface Methodology (RSM). Statistical regression models for prediction of dehydration and desalting rate wereobtained. Then, theoptimum process parameters for Yaregskoye oil and a number of otheroils were obtained on the pilotELOU plant, including heavy high viscosity oil from the Verbluzhy Field, heavy karbonskaya oil, mediumDevonskaya oil and light Sostinskaya oil. Based on the dataobtained, graphical modelsforpredicting optimal values of the process parameters are determined.

Influence of technological parameters of the middle distillate fractions catalytic dewaxing process on its effectiveness
Keywords: fuel, low-temperature properties of diesel fraction, catalytic dewaxing of middle distillate fractions,mathematical model of catalytic dewaxing process.
Abstract.This work considers the influence of feed rate and hydrogen-containing gas flow rate on the yield and quality of the diesel fraction obtained in the process of catalytic dewaxing of middle distillate fractions using the mathematician model. It is shown that the yield of the diesel fraction and its low-temperature properties depend on the feedrate and hydrogen-containing gas flow rate. An increase inthe feed rate from 240 to 360 m3/h leadsto an increase in the yield of the diesel fraction from 58 to 63%.
Moreover, a decline ofits low-temperature properties by 1-4°C (atT =300°C) and 4-7°C (atT = 340°C) due toan increase in the contact time of the raw material withthe catalyst.The increase of the hydrogen- containing gas flowrate from 5000 to 50000 m3/hr, on the contrary, leads to a decrease in the yield of the diesel fraction by 3-5%. In addition, it leads to improvement of diesel fraction slow-temperature properties by 3-4°C for different feedstock compositions, which is associated with increased
hydrocracking reactions leading to formation of lighter hydrocarbons with lower meanings of freezing temperature and cold filter plugging point.

Keywords: reactor, pitching, coke sediments, coking, coke mass.
Abstract. In the proposed technology forthe delayed coking unit reconstruction, main products are pitch and coke produced simultaneously at one unit, andthe process cycle includes the stages of pitching, coking, the reactor preparation to stop, slack time, and the reactor preparation for start-up, thatare carried out sequentially in the same reactor withthe above steps followed by transferto a second reactor,then the process cycle is repeated. New technology helps to reduce the unit downtime, to fully mechanize the process of reactor cleaning, to increase the feed resources due to the residual products, to expand therange of marketable products, to reduce the petroleum products losses, to improve the environmental performance of the process, to reduce the operating and capital costs.
