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.

    Optimal design of plate-and-frame heat exchangers for efficient heat recovery in process industries
    (Elsevier Inc., 2011) Arsenyeva, O. P.; Tovazhnyansky, L. L.; Kapustenko, P. O.; Khavin, G. L.
    The developments in design theory of plate heat exchangers, as a tool to increase heat recovery and efficiency of energy usage, are discussed. The optimal design of a multi-pass plate-and-frame heat exchanger with mixed grouping of plates is considered. The optimizing variables include the number of passes for both streams, the numbers of plates with different corrugation geometries in each pass, and the plate type and size. To estimate the value of the objective function in a space of optimizing variables the mathematical model of a plate heat exchanger is developed. To account for the multi-pass arrangement, the heat exchanger is presented as a number of plate packs with co- and counter-current directions of streams, for which the system of algebraic equations in matrix form is readily obtainable. To account for the thermal and hydraulic performance of channels between plates with different geometrical forms of corrugations, the exponents and coefficients in formulas to calculate the heat transfer coefficients and friction factors are used as model parameters. These parameters are reported for a number of industrially manufactured plates. The described approach is implemented in software for plate heat exchangers calculation.

    Process integration of sodium hypophosphite production
    (Elsevier Inc., 2010) Tovazhnyansky, L. L.; Kapustenko, P. O.; Ulyev, L. M.; Boldyryev, S.; Arsenyeva, O. P.
    The case study of flexible integrated flowsheet development for sodium hypophosphite production is presented. It is based on phosphoric sludge utilization process. The weight concentration of phosphorous in raw materials is equal to 30e50%. The reaction and separation parts of the system were designed based on detailed analysis of production stages. After that the process equipment was selected. Process modelling is made for annual production of hypophosphite equal to 2500 t. It permitted to extract process streams for heat energy integration and to define their parameters. The operating pinch procedure was used to estimate the consumption of hot and cold utilities for non-integrated process. The influence of utilities cost on minimal temperature difference is investigated. Analysis of heat system topology modification depending on energy prices is conducted. Optimal structure of heat recovery system and minimal temperature difference are determined. It is shown that optimal integrated process consumes 45% of hot and 30% of cold utilities required by non-integrated process.

    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.

    (Наука, 2013) Boldyryev, S. A.; Garev, A. O.; Klemeš, J. J.; Tovazhnyansky, L. L.; Kapustenko, P. O.; Perevertaylenko, O. Yu.; Arsenyeva, O. P.
    The possibility of utilizing the low potential heat of the ammonia refrigeration cycle has been shown. The design of an energy saving heat exchangers network to heat water and air in municipal buildings has been proposed. The possibility of increasing the pressure of ammonia with the purpose of improving the heat recovery in the system and reducing the load of the heating and cooling systems was considered. The minimum temperature difference in the heat exchangers network was selected. The economic efficiency of the retrofit project was estimated.
