Від 2005 року кафедра має назву "Інтегровані технології, процеси і апарати", первісна назва – кафедра загальної хімічної технології, процесів і апаратів.

Кафедра загальної хімічної технології, процесів і апаратів створена в 1933 році, а очолив її професор Максим Ісидорович Некрич, який у свій час закінчив Паризький університет – Сорбонну (Франція). Але ще в 1927 році професор М. Д. Зуєв починає читати студентам курс загальної хімічної технології, доповнюючи його розрахунком процесів і апаратів, а також контрольно-вимірювальних приладів. У 1964 році від кафедри загальної хімічної технології, процесів і апаратів відокремилася нова кафедра – "Автоматизації хімічних виробництв".

Від 1977 року кафедру очолював Леонід Леонідович Товажнянський, кандидат технічних наук, доцент, на той час проректор ХПІ, а згодом – доктор технічних наук, професор, Заслужений діяч науки і техніки України, Заслужений працівник вищої школи, лауреат Державної премії, Дійсний член Академії наук вищої школи України, ректор НТУ «ХПІ». Виконувачем обов’язків завідувача кафедри у період з 1977 по 1981 роки був І. С. Чернишов.

Від 1 лютого 2018-го року кафедра входить до складу Навчально-наукового інституту хімічних технологій та інженерії Національного технічного університету "Харківський політехнічний інститут".

У складі науково-педагогічного колективу кафедри працюють: 2 доктора та 12 кандидатів технічних наук; 2 співробітника мають звання професора, 11 – доцента.

About the Possibilities of the Heat Exchangers Network Retrofit for Post-Combustion CO₂ Capture Unit Without Stream Split
(The Italian Association of Chemical Engineering, 2014) Perevertaylenko, O. Yu.; Gariev, A. O.; Damartzis, Theodoros; Tovazhnyanskyy, Leonid Leonidovich ; Kapustenko, P. O.; Arsenyeva, O. P.
There is an increasing interest in post-combustion CO2 capture connected with climate change and further use of captured CO2 in enhanced oil and gas recovery and as a feed to produce such products as methanol, dimethylether and others, use in hot dry rock technologies etc. The currently used post-combustion method with monoethanolamine (MEA) absorption without stream split has two shortcomings: significant steam consumption to regenerate amine solution and relatively high cost of heat exchange equipment of absorption unit or Heat Exchange Network of Absorption Unit (HEN AU). The variation of temperature differences on rich/lean heat exchanger was considered and its influence on heat supply, cost of HEN AU and cold utility consumption was searched. The high effective plate heat exchangers are proposed as components of HEN AU to decrease its cost. The possibility of flue gas stream heat integration for heat supply to the desorber was searched too.
Accounting for fouling in plate heat exchanger design
(The Italian Association of Chemical Engineering, 2007) Gogenko, A. L.; Anipko, O. B.; Arsenyeva, O. P.; Kapustenko, P. O.
The fouling removal mechanism for plate heat exchanger (PHE) heat transfer surface controlled by shear stress is considered. The semi-empirical formula to predict asymptotic value of fouling thermal resistance velocity dependence based on heat and momentum transfer analogy is proposed. The correlation is in a good agreement with literature data and was checked for PHEs installed in District Heating systems of a number of cities in Ukraine. As a result the modified method for PHE heat transfer surface area calculation is proposed, which takes into account the influence of flow velocity and heat transfer enhancement in channels on fouling thermal resistance. The obtained correlation can also be used for estimation of fouling rate in process PHEs where one media is water, e.g. in distilleries, nitric and phosphoric acids, fertilizers productions.
Accounting for Thermal Resistance of Cooling Water Fouling in Plate Heat Exchangers
(The Italian Association of Chemical Engineering, 2012) Arsenyeva, O. P.; Tovazhnyanskyy, Leonid Leonidovich ; Kapustenko, P. O.; Demirskyy, O. V.
The Plate Heat Exchanger (PHE) is one of the most efficient types of modern heat exchangers. Heat transfer enhancement is one of the main features of PHEs, and lower fouling tendencies render them even more advantages for the use in different applications. The effects on fouling accumulation rate of process parameters in PHE channels of intricate geometry are studied in this article. The asymptotic behavior of the water fouling on heat transfer surfaces is examined. The fouling accumulation rate is described as a difference between the fouling deposition term and the fouling removal term. On comparison with data for fouling on different heat transfer surfaces available in literature it is shown that asymptotic fouling thermal resistance inversely proportional to wall shear stress. The proportionality coefficient in this relation is determined for a number of considered cases. To calculate the wall shear stress the equation for PHE channel main corrugated field is used, which accounts for corrugations geometrical parameters. It is shown that for given fouling properties of water this coefficient is constant and can be determined by monitoring fouling behavior of any item of heat exchangers working on specific enterprise. After that all other heat exchangers of that enterprise can be calculated using that data and developed Equation for accounting of fouling in their design.

Decrease in permeability that occurs during the construction of the well and operation are analyzed. The reasons for the decrease in the permeability of the bottom-hole zone in the reservoir rocks that occur in the process of drilling, cementing, reopening and development of wells are determined. The basic principles of acid treatment for intensification of hydrocarbon raw material extraction of sealed productive strata in the process of their drilling are investigated. The solution for acid treatment is given. Specialized products for stimulation are considered. Acid treatments quality increasing through new working agent’s usage and improving the technology analysis is performed: the scientific substantiation of the program realization algorithm of possible influence for concrete geological and physical conditions of a well is presented; systems of geological and technological factors influencing the filtration properties of reservoirs are identified and analyzed; identifying features of development and adaptation types of chemical compositions for specific conditions of the formation; the possibility of conducting experimental research on the development and adaptation the chemical compositions and technologies of influence in the processes of increasing productivity and silencing of wells in relation to specific geological and physical conditions is determined.
Advantages of using channels with different corrugation height in the plate heat exchangers
(Технологический центр, 2018) Khavin, G. L.; Babak, Tatyana
In the case when there is a difference in consumption on the side of the cold and hot heat carriers, the use of channels with the same corrugation height in one heat exchanger leads to a decrease in velocity of the heat carrier on the side with low consumption. Low velocity contributes to appearance of deposits on the heat transfer surface, which leads to disruption of operation mode of the apparatus and a forced clean-up stop. In case of using channels with a different corrugation height (cross-section area), velocities in the channels are aligned and intensity of emergence and growth of contamination falls sharply. It also allows us to reduce the heat transfer surface area of the apparatus and fully implement permissible pressure losses on the sides of the heat exchanger. For designing of heat exchangers of this structure, the authors developed the mathematical model that allows making calculations of heat exchangers for assigned operation conditions with the use of geometrical data of the plates, thermophysical properties of heat carriers and criterial equations for plates of the selected type. The calculation algorithm involves determining of the ratio between corrugation heights. Practical value lies in the fact that the proposed approach makes it possible to extend the service life of the heat exchanger prior to a maintenance stop. This enables provision of continuity of the technological process and decreases operation costs. Calculation of the heat exchanger of hot water supply by the parallel scheme of attachment to heating networks and the heat exchanger of stage 1 of the two-stage hybrid scheme was presented. Calculation data indicate a decrease in the heat transfer surface area compared to heat exchangers with channels of equal height, full realization of pressure losses and their alignment in the channels, which facilitates an increase in resistance to contamination of the plates’ surface. Calculation showed the advantage of using apparatuses with channels of different cross-section area. The higher the ratio between consumption of heat carriers in the channels, the stronger this advantage.
Ammonia Refrigeration Cycle Integration in Buildings Heating System
(The Italian Association of Chemical Engineering, 2012) Boldyryev, S. A.; Kapustenko, P. O.; Tovazhnyanskyy, Leonid Leonidovich ; Garev, A. O.; Perevertaylenko, O. Yu.; Khavin, G. L.; Arsenyeva, O. P.; Klemeš, Jiří Jaromír
This work investigates the possibility of ammonia low potential heat utilisation with use of Process Integration methodology. The two operation modes are considered. The first one is the use of ammonia gas super-heating and partly ammonia condensation. The low condensation temperature of ammonia is limiting the low potential heat usage. The second option is introduction of ammonia additional compression to increase the temperature of ammonia condensation. The low potential heat consumers are the hot water supply system, air pre-heating system and air heating for the fans.
Analysis of modern power efficient systems development strategies
(Національний технічний університет "Харківський політехнічний інститут", 2020) Goncharov, Evgen Viktorovych; Polyakov, I. V.; Markov, V. S.; Kryukova, N. V.; Boykov, D. A.; Skrebtsov, N. K.; Tsebriuk, I. V.
The article analyzes the existing methods and ways of developing and improving information and energy systems and grids. A number of questions are analyzed regarding the prospects for the development of information and energy systems and power lines. It has been determined that the basis of the electric power industry is the integrated energy system, which provides centralized energy supply to domestic consumers, interacts with the energy systems of neighboring countries, and ensures the export and import of electric power. It is concluded that in recent years, the so-called “cloud technologies” have become increasingly popular. From an analysis of the current state of the electric power industry, it follows that the need for its modernization and improvement. Accordingly, in connection with the transition of the world electric power industry to energy-efficient technol ogies, the main attention should be directed to studying the connection between the processes of transmission and distribution of electric power, as well as the related “smart” measurements, issues of the operation of energy markets and the operation of regulatory standards. It was noted that with the creation of the concept of “smart grids”, it is important to develop appropriate regulatory and technical support for the integration of dispersed energy sources using existing modern power electronics devices and storage devices, which will lead to the creation of a capacity management platform based on modern technologies. It is noted that the possibility of functioning in real time is provided due to the specific organization of the information grid, rather than an electric grid, which is provided due to the specific organization of the information grid. The results of the analysis indicate that the control information center must have sufficient computing power and bandwidth of the computing grid as well as spare computing power capacities to permanent operability assurance.

(The Italian Association of Chemical Engineering, 2016) Ved, V. E.; Krasnokutskiy, E. V.; Satayev, M. I.; Ved, A. V.; Saipov, A. A.
There are theoretically founded principles of catalytic converters designing of harmful gas emissions of various heat devices. Experimental investigations have shown that the smallest aerodynamic losses in the constructions of gas neutralizers are achieved at the using of profiled ceramic blades as working units - carriers of catalysts. To ensure intensive mixing of the flow inside the converter the input edges of the blades grids of the future stages should be located between the output edges of the blades of the grids of the preceding stages.

Capital Cost Targeting of Total Site Heat Recovery
(The Italian Association of Chemical Engineering, 2012) Nemet, Andreja; Boldyryev, Stanislav; Varbanov, Petar Sabev; Kapustenko, P. O.; Klemeš, Jiří Jaromír
Exploiting heat recovery on Total Site level offers additional potential for energy saving through the central utility system. In the original Total Site Methodology (Klemeš et al., 1997) a single uniform ΔTmin specification was used. It is unrealistic to expect uniform ΔTmin for heat exchange for all site processes and also between processes and the utility system. The current work deals with the evaluation of the capital cost for the generation and use of site utilities (e.g. steam, hot water, cooling water), which enables the evaluation of the trade-off between heat recovery and capital cost targets for Total Sites, thus allowing to set optimal ΔTmin values for the various processes. The procedure involves the construction of Total Site Profiles and Site Utility Composite Curves and the further identification of the various utility generation and use regions at the profile-utility interfaces. This is followed by the identification of the relevant Enthalpy Intervals in the Balanced Composite Curves. A preliminary result for evaluation of heat recovery rate and capital cost can be obtained.
Catalyst Coatings Carriers Based on Aluminium-Silicon Glass Crystalline Compositions
(The Italian Association of Chemical Engineering, 2017) Krasnokutskiy, E. V.; Ved, V. E.; Tovazhnyanskyy, Leonid Leonidovich ; Ved, H. V.
A method of deposition on the surface of metals or ceramics catalytically active compounds by attaching them to the intermediate glass crystalline coatings. The effect of the presence of 3d-transition elements in the intermediate coating to modify the activity of a palladium containing catalyst was studied. The basic indicators of the efficiency of non-isothermal heterogeneous catalytic conversion process of benzene depending on the types of transition metals which are part of the intermediate coating were studied. Comprehensive analysis of the morphology of a glass-intermediate secondary catalyst carriers and surface coating them with layers of catalytically active compounds was carried out, which allowed to estimate the effect of the characteristic features of the structure of the coating surface on the rate constant of the process of conversion and mass transfer coefficient.
CFD Modelling of Hydrodynamics and Heat Transfer in Channels of a PHE
(The Italian Association of Chemical Engineering, 2013) Stogiannis, I. A.; Paras, S. V.; Arsenyeva, O. P.; Kapustenko, P. O.
Plate Heat Exchangers (PHEs) are one of the most efficient types of contemporary heat exchangers with intensified heat transfer. They are commonly used in process industries due to their compactness, lower weight and cost, smaller space for installation and servicing compared to conventional shell-and-tube heat exchangers. Heat transfer in PHEs takes place in channels of complex geometry formed by corrugated plates placed abutting. The flow in such channels can be very complicated due to breakup and reattachment of the boundary layer, secondary flows and the small hydraulic diameter of the flow passages. The aim of this work is to compare a well-established and validated CFD code both with results obtained from an experimental PHE model using a corrugated plate commonly used in industrial applications and with existing correlations. The results show that CFD simulation can predict heat transfer rate and fluid flow behaviour in a range of Re numbers (8,900 to 27,650), with discrepancies up to 1 % and 6 % in terms of outlet temperature and pressure drop respectively. Modelling of the flow inside a single corrugation also allows for computation of the wall shear stress distribution which can be very useful in PHE applications where fouling is of particular importance.
The Choice of the Optimal Retrofit Method for Sections of the Catalytic Reforming Unit
(The Italian Association of Chemical Engineering, 2014) Ulyev, L. M.; Kapustenko, P. O.; Nechiporenko, D. D.
Hydrotreating section and catalytic reforming section of catalytic reforming unit L-35-11/600 were examined in this paper. This unit was designed for processing large fraction of naphtha by catalytic reforming in order to obtain components of gasoline with an octane number 78-85 points. Pinch diagnostics for these sections was carried out. Comparative economic analysis of their effectiveness after the proposed retrofit was performed for each section separately and for the total their flowsheet. The implementation of the Pinch Method for hydrotreating section will reduce energy intensity by 2.2 MW. Energy consumption for catalytic reforming section reduced by 6.4 MW. Energy consumption for joint integration of hydrotreating section and catalytic reforming section reduced by 11.4 MW. Therefore, it was concluded that Pinch design for these sections of catalytic reforming unit L-35-11/600 is most advisable to carry out for the two sections together.

Computer Aided Design of Plate Heat Exchangers
(Elsevier Inc., 2010) Arsenyeva, O. P.; Tovazhnyansky, L. L.; Kapustenko, P. O.; Khavin, G. L.
The computer aided design of plate heat exchanger with mixed grouping of plates is considered. It is formulated as the mathematical problem of finding the minimal value for implicit nonlinear discrete/continues objective function with inequality constraints. The optimizing variables include the number of passes for both streams, the numbers of plates with different corrugation geometries in each pass, the plate type and its size. To estimate the value of objective function in a space of optimizing variables the mathematical model of plate heat exchanger is developed. To account for thermal and hydraulic performance of channels between plates with different geometrical forms of corrugations, the exponents and coefficients in formulas for heat transfer coefficients and friction factors calculation are used as model parameters. The procedure and software for numerical experiment to identify model parameters by comparing the calculation results with those obtained with free available in web computer programs of plate manufacturers is developed. The sets of such parameters are obtained for a number of industrially manufactured plates. The described approach is implemented as software for plate heat exchangers calculation.
