Сучасна назва – кафедра "Технологія переробки нафти, газу і твердого палива", попередня – "Технологія палива та вуглецевих матеріалів".

У перші роки існування ХПІ їх попередниці входили до складу хімічного відділення. Усі розділи хімії спочатку були представлені однією кафедрою хімії, з часом створювалися кафедри технологічного профілю, зокрема з хімічної технології мінеральних речовин та барвників. Серед випускових технологічних кафедр хімічного спрямування ХПІ була і кафедра технології органічних та фарбувальних речовин. У 1885 році професор Валерій Олександрович Гемеліан першим почав читати лекції з дисципліни "Хімія та технологія барвників і їх використання".

Кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут".

Підготовка здійснюється за такими основними напрямами: – Переробка нафти з отриманням широкого спектру товарних нафтопродуктів; – Проектування устаткування процесів переробки нафти, вугілля та газового конденсату; – Методи оцінки якості нафти, нафтопродуктів (бензину, дизельного пального), вугілля та газу; – Виробництво альтернативного палива; – Переробка нафтошламів; – Виробництво усіх видів мастил та моторних олив, присадок; – Виробництво синтез-газу; – Коксування, газифікація вугілля; – Виробництво графітових матеріалів; – Очищення та знезараження стічних вод.

    Improvement of an engineering procedure for calculating the non­isothermal transportation of a gas­liquid mixture
    (Технологический центр, 2019) Fyk, M. I.; Biletskyi, V. S.; Fyk, I.; Bondarenko, Volodymyr; Mohammed, Bassam Al-Sultan
    The study that we conducted into the process of transportation of a gas-condensate mixture from a well bottom to the separation production plant has revealed the features of isothermal and non-isothermal flow. It was proved that during non-isothermal flow, hydraulic losses in the product pipeline are significantly affected by throttle effect and energy accommodation effect. The influence of velocity and volumetric flow rate of the gas-liquid mixtures on hydraulic resistance and pressure drop on a section of product pipeline, taking into consideration non-isothermal flow was analyzed. It was found that the assessment of hydraulic resistance and pressure drop in the proposed dependences converges with standardized ones by 95 %. The result was obtained based on the developed system of equations of the mathematical model for non-isothermal non-stationary one-dimensional motion of the gas-liquid mixture of hydrocarbons in the pipeline. The proposed system beneficially differs from the known ones by the fact that it takes into consideration the inner convective heat exchange, estimated by the combined effect of Joule-Thomson. A distinctive feature of the improved procedure for calculation was the introduction of temperature correction and accommodation coefficient in the calculation of hydraulic resistance of a pipeline as a system with distributed parameters. Due to this, it became possible to improve the procedure for the calculation of non-isothermal transportation of a homogeneous gas-condensate mixture. Based on the analysis of calculation curves by the known procedures (formulas of Thomas Colebrooke, Leibenson and VNIIgas) for isothermal and non-isothermal processes and the proposed procedure, rational areas of their applications were shown. All calculations were performed at the velocity of a gas-liquid flow within the range 0–50 m/s, pipe roughness of 0.01–0.05 mm and their diameter of 100–300 mm, the data from actual production pipelines of Novotroitsk oil-gas condensate field were used. Comparison of the theoretical and industrial experiments showed sufficient for engineering practice accuracy of calculation of pressure drop on the stretches of oil and gas lead lines and allowed recommending the developed analytical dependences for the introduction in industrial engineering.

    Theoretical and applied aspects of using a thermal pump effect in gas pipeline systems
    (Технологический центр, 2018) Fyk, M. I.; Fyk, I.; Biletskyi, V. S.; Oliynyk, Max; Kovalchuk, Yulia; Hnieushev, Volodymyr; Shapchenko, Yevhen
    Based on the classical method for calculating parameters of gas pipelines using electrohydraulic analogy, a mathematical model of the object, the process of gas transmission in an industrial pipeline, has been developed. The study subject was the change of gas temperature after its passing through a throttling device which brings about thermal pump effect in the receiving strand of the gas pipeline. It was proposed to use gas-dynamic thermal pumps to minimize the risk of plug and hydrate formation in the gas pipeline of Kharkivtransgaz Co. It was shown that the change of the ground body temperature by ±10 °C in the 20 km long gas transmission section of the multi-strand pipeline system causes a change of gas pressure by 5−15 %. A theoretical-empirical formula for determining the Joule-Thomson coefficient was derived which allows one to estimate the thermal pump effect on the energy and thermobaric parameters of nonstationary gas transmission processes. It was determined that the integral coefficient of performance (COP) for the network system of multi-strand pipelines including gas-dynamic thermal pumps varies within the range of 1.00‒1.09 depending on the ambient temperature (0−20 °C). The principles of constructing the topology of the diagram of the gas pipeline with bridges and branches which, due to the use of the thermal pump effect, ensures a minimal risk of plugging and hydration consist in activation and regulation of the energy-transforming and heat exchange processes in the sections of the network system. This is achieved by introduction of additional throttling devices in front of the bridges and branches of the pipeline and by checking for proximity and bordering with critical temperatures of plug and hydrate formation.

    Improvement of technological-mathematical model for the medium-term prediction of the work of a gas condensate field
    (Технологический Центр, 2016) Kutia, Mykhailo; Fyk, M. I.; Kravchenko, Oleg; Palis, Stefan; Fyk, I.
    Authors proposed analytical and algorithmic additions to the mathematical model of the prediction of the work of a gas­condensate field in the gas regime. The developed technique of improved calculations of the gas­dynamic parameters was verified by the actual history of a number of real fields in Ukraine. It demonstrated good results by accuracy in the course of medium­term prediction, which is important for estimating the efficiency of the measures for the intensification of well production. The new analytical construction of the systems of equations of the plane­radial inflow of gas to the well bottom and transport of gas by the vertical column allowed us to make the algorithm of iterative calculations more universal. The universality consists, in particular, in the possibility to predict the results of thermobaric changes in the gas flow and changes in the design parameters of a well after technological measures for the intensification of well production. The unique difference is the possibility of rapid evaluation of the prediction of intensification of a well with the interference into both the productive layer and the downhole equipment. Authors emphasized the need for a similar further improvement of the technological­mathematical model taking into account the new technologies of intensification, including innovative technological schemes of constructing the downhole equipment, equipment for the column of wells, wellhead equipment, multi­bottom and multi­row systems of extraction, extraction of gas with injection into the layer of special chemical agents. The certain properties of the adaption correction of parameters made it possible to use the program realization of the developed technological­mathematical model at the Ukrainian­Swedish gas­extraction company TOV "Karpatygaz".

    Purpose. Parallel synchronized calculation of networks with certain hydraulic and thermal properties of separate oil pipelines, which is possible with the use of a two-layer bond graph and a complex methods of potentials in nodes and methods loop currents in circuits. The authors propose to link two layers of graphs of the scheme using the equation of state of oil as a gas-liquid mixture, which will simplify and increase the speed of calculations. Findings. The principles of operation of the ball valve of the shut-off valve and its main differences from the flopper shutter are considered in detail. Also, the geometric parameters of the ball itself are demonstrated in detail. Examples of design are given, and the operating principle of the most common models of shut-off valves is described. Originality. The connection of the hydraulic and thermal layer of the bond-graph is realized by taking into account the average temperatures and the total heat transfer coefficient on the branches of the graph. Practical implications. The developed system of equations of the two-layer bond graph is applied to an estimation of work of networks of oil pipelines at designing and change of operational modes.
