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.

The effect of plate corrugations geometry on performance of plate heat exchangers subjected to fouling
(The Italian Association of Chemical Engineering, 2019) Matsegora, Oleksandr Ivanovich; Klemeš, Jiří Jaromír; Arsenyeva, Olga Petrovna; Kapustenko, Petro Oleksiyovych; Kusakov, Sergey Konstantinovich; Zorenko, Victor Vladimirovich
The novel approach of estimating the influence of plate corrugations geometry on plate heat exchanger (PHE) operation in conditions of fouling is proposed. It is based on the presented mathematical model of the PHE with commercially produced plates. To account for fouling on the heat transfer surface, the fouling model of reaction and transport type presented in dimensionless form is employed. The influence of plate corrugations geometry on PHE performance is discussed on results of modelling PHE installed for thin juice heating at evaporation station of the sugar factory. The corrugations inclination angle to the main flow direction is considered as the main influencing parameter. The effect of this parameter on fouling intensity is shown for the cases when the plates with different corrugations angle are used in one PHE. The measures to mitigate fouling in PHE by optimal selection of plate corrugations geometry are discussed.
Mathematical modelling of the thermal and hydraulic behaviour of plate heat exchanger in the fouling conditions
(The Italian Association of Chemical Engineering, 2018) Kapustenko, Petro Oleksiyovych; Demirskiy, O. V.; Tovazhnyanskyy, Leonid Leonidovich; Klemeš, Jiří Jaromír; Matsegora, O. I.; Arsenyev, Pavlo Yurievich; Arsenyeva, Olga Petrovna
The mathematical model of Plate Heat Exchanger (PHE) subjected to fouling is proposed. It is represented by the system of ordinary differential equations. The model is accounting for the distribution of process parameters along the PHE channel that allows predicting fouling development in time at different locations along the channel length. The development of the fouling deposit is accounted with the fouling model presented by the equation in dimensionless form. The relative influence of different terms is characterized by empirical coefficients which can be identified with the data of monitoring the PHE thermal and hydraulic performance. The model allows also the prediction of pressure drop variation in PHE with the development of fouling deposition layer and respective reduction in channels cross-section area. The application of the model and its accuracy is demonstrated with two case studies considering the monitoring of PHEs thermal and hydraulic performance in the industry at sugar factory and in District Heating system.
Mathematical model of plate heat exchanger for utilisation of waste heat from condensable gaseous streams
(The Italian Association of Chemical Engineering, 2018) Kapustenko, Petro Oleksiyovych; Demirskiy, O. V.; Tovazhnyanskyy, Leonid Leonidovich; Klemeš, Jiří Jaromír; Vasilenko, O. A.; Kusakov, S. K.; Arsenyeva, Olga Petrovna; Khusanov, A. E.
The mathematical model of vapour condensation from the mixture with noncondensing gas in Plate Heat Exchanger (PHE) channels is presented. The model accounts for the change of process parameters along the heat transfer surface and local features of heat and mass transfer processes in PHEs channels with plates of different corrugations geometry. It consists of the system of ordinary differential equations with considerably nonlinear right parts. The software for its solution by finite difference method is developed. The validity of the model is confirmed by comparison with the experiment for steam-air mixture condensation in a PHE channel sample.
The optimal design of welded plate heat exchanger with intensified heat transfer for ammonia synthesis column
(The Italian Association of Chemical Engineering, 2019) Arsenyev, Pavlo Yurievich; Tovazhnyanskyy, Leonid Leonidovich; Klemeš, Jiří Jaromír; Arsenyeva, Olga Petrovna; Perevertaylenko, Oleksandr Yurievich; Kapustenko, Petro Oleksiyovych
The modification of heat exchanger networks of industrial enterprises targeting energy saving solutions requires proper heat transfer equipment. The estimation of the optimal design parameters for heat exchangers requires reliable mathematical models for the description of the thermo-hydraulic processes inside the channels, and adequate optimisation methods. This work proposes the novel mathematical model and optimisation algorithm for the selection of welded plate heat exchanger (WPHE) operating in ammonia synthesis column. It enables finding the optimal design with the specified shape of the corrugated plates, distribution of flows and number of plates and passes. The developed algorithm is implemented in Mathcad software. The application of the proposed approach is illustrated by example in which the resulted WPHE with the cross flow in one pass and overall symmetric counterflow of streams has shown a reduction of heat transfer area 25 % compared to previously tested in industry WPHE with unsymmetric passes arrangement.
Eco-Friendly Synergetic Processes of Municipal Solid Waste Polymer Utilization
(The Italian Association of Chemical Engineering, 2018) Bukhkalo, S. I.; Klemeš, Jiří Jaromír; Tovazhnyanskyy, Leonid Leonidovich ; Arsenyeva, O. P.; Kapustenko, P. O.; Perevertaylenko, O. Yu.
The synergetic approach for eco-friendly efficient utilization of Polymer Solid Waste is presented. It is accounting for chemical processes in polymers during the use of the original product and at the stage of its waste recycling. The study of the polymer photoconductive degradation based on analysis of chemical reactions in the polymer film is presented. It is discussed how to predict the properties of the polymer after its use and to develop the efficient technique for its recycling. The recycling technique is demonstrated on examples of recycling polyethylene film by chemical foaming and injection moulding methods. The results of factorial experiments on the influence of different process parameters on process intensity and secondary product quality are presented. The results are used for developing modern technologies for the processing of polymer solid wastes into useful secondary products.
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.
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.
Targeting Minimum Heat Transfer Area for Heat Recovery on Total Sites
(The Italian Association of Chemical Engineering, 2013) Boldyryev, S.; Varbanov, Petar Sabev; Nemet, Andreja; Kapustenko, P. O.; Klemeš, Jiří Jaromír
This paper upgrades the Total Site integration methodology, when accounting for a trade-off between capital and heat recovery by selection of optimal temperature levels for intermediate utilities and therefore, decrease capital cost. Heat transfer area for recuperation in Total Site is a two-fold problem and it depends on the Sink Profile on one side and on the Source Profile on another. The resulting temperature of intermediate utility is a result of a trade-off since the heat transfer area on Source side is decreasing, when temperature of IM is decreasing, however increased on Sink side. In the opposite higher intermediate utility temperature leads to higher area on the Source side and lower on Sink side. The temperature of each intermediate utility may be varied between specified lower and upper bounds subject to serving the Sink and Source Profiles.
