Від 1999 року кафедра має назву "Хімічна техніка та промислова екологія", попередня назва – кафедра механічного устаткування хімічних виробництв.

Кафедра механічного устаткування хімічних виробництв була організована 18 жовтня 1946 року у складі факультету технології неорганічних речовин Харківського хіміко-технологічного інституту. Становлення кафедри пов’язане з іменами доцентів Георгія Веніаміновича Петрова, М. Ковальова, Абрама Натановича Цейтліна, Анісіма Рудольфовича (Рувиновича) Ястребнецького . У 1960 році на базі кафедри створено Факультет хімічного машинобудування.

Кафедра входить до складу Навчально-наукового інституту механічної інженерії і транспорту Національного технічного університету "Харківський політехнічний інститут".

У складі науково-педагогічного колективу кафедри працюють: 2 доктора та 14 кандидатів технічних наук, 4 доктора філософії; 3 співробітника мають звання професора, 12 – доцента.

    The object of the study is the content of antioxidants and the induction period of accelerated oxidation under simulated conditions of the lipid component of the emulsion system. The way to solve the problem of developing compositions of oxidation-stable emulsion systems based on nutritionally valuable oils, in particular hemp oil, by adding natural physiologically active antioxidants is considered. The research is relevant in the context of finding effective storage methods and extending the shelf life of products using hemp oil. The feature of the work lies in determining the influence of the composition of emulsion systems based on hemp oil on chemical oxidation during storage. The content of stabilizers in the hemp oil emulsion system (lecithin – 0.8...1.0 %; xanthan gum – 0.0...0.1 %) is proposed, which is effective in the inhibition of oxidative spoilage. The content range of β-carotene (0.012 %) in model emulsion systems is outlined, the addition of which increases the induction period of accelerated lipid oxidation by 1.58...2.08 times. The peroxide value of the lipid component of the emulsion system during storage at different temperature conditions (0...15 °C) and during different storage periods (15...60 days) was studied. The results of the study confirm the significant influence of the composition of emulsion systems on the chemical oxidation of the lipid component, which is important for ensuring the quality and stability of food, pharmaceutical and cosmetic products. An applied aspect of the obtained scientific result is the possibility of modeling the composition of emulsion systems based on valuable hemp oil depending on the ratio of polyfunctional antioxidants of the oil component.

    Development of a highly efficient combined apparatus (a combination of vortex chambers with a bin) for dry dedusting of gases
    (ПП "Технологічний Центр", 2019) Pitak, Inna V.; Shaporev, Valery P.; Briankin, Serhii S.; Komarysta, Bohdana; Nechyporenko, Dmytro
    The use of dust collectors of a new type which combine the operation principle of centrifugal and louvre-vortex apparatuses was considered. The use of a heterogeneous reactor for gas-solid systems with two streams in a cyclone, a direct-flow cyclone with a chamber of preliminary collision of gas-dust flows, as well as improved designs of vortex chambers was considered. A combined dust collector was presented in a form of the Rankine vortex tube in combination with a bin in which louvre-vortex devices are installed. The combined deduster under study provides an organized supply of a gas-dispersed system at adjustable hydrodynamic conditions to louvre-vortex devices used as the dedusting apparatus. It was assumed that the processes of coagulation of particles under appropriate hydrodynamic conditions as well as partial destruction of harmful gas impurities in a continuous phase will take place in the vortex tube. Thus, development of a substantiated physical model (of a design) of a combined dust collector for specified initial conditions and operability of the design were considered on the basis of theoretical and experimental provisions. It has been established that creation of hydrodynamic conditions in centrifugal devices and pipelines is the most promising direction of increasing the degree of dedusting of a gas-dispersed flow. These conditions must ensure supply of the gas-dispersed system to the centrifugal apparatus to ensure agglomeration of fine particles. Design of a dedusting apparatus in which intense collision of dust particles in a special chamber and their agglomeration and subsequent separation supposed to proceed in a chamber which is actually a cyclone is an expedient and effective solution. It provides the degree of purification of the gas and dust flow at a level of 98-99 % regardless of particle size.
