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.

    Improvement of the technology of fatty acids obtaining from oil and fat production waste
    (PC Technology center, 2022) Kalyna, Viktoriia; Stankevych, Serhii; Myronenko, Liliia; Hrechko, Andrii; Bogatov, Oleg; Bragin, Oleksandr; Romanov, Oleksii; Ogurtsov, Yuriy; Semenov, Evgeny; Filenko, Olesya
    Fatty acids are an important component in the pharmaceutical, food, chemical industries. The production of various types of products requires a certain purity and quality of fatty acids. To obtain these compounds, it is promising to use soapstocks, which are waste products of alkaline refining of oils. The peculiarity of the work lies in determining the effect of the process parameters of soapstock decomposition with sulfuric acid on the saponification number, which is an important production characteristic of fatty acids. The study used sunflower soapstock according to DSTU 5033 (CAS 68952-95-4) with a mass fraction of total fat of 69.5 %, fatty acids – 64.5 %. The soapstock was treated with a sulfuric acid solution at a temperature of 90 °C, the process duration was 40 min. Rational parameters of soapstock treatment were determined: concentration of sulfuric acid in the reaction mass is 80 %, concentration of an aqueous solution of sulfuric acid – 50 %. In the experiment interval, the settling duration of the reaction mass does not affect the saponification number of fatty acids. The settling time of 1 hour is effective for the isolation of fatty acids. Under these conditions, the saponification number of fatty acids was 186.4 mg KOH/g. The acids correspond to fatty acids of the first grade according to DSTU 4860 (CAS 61788-66-7): mass fraction of moisture and volatile substances – 1.2 %, mass fraction of total fat – 97.5 %, cleavage depth – 95.0 % oleic acid. The obtained data allow rational and most efficient use of the reagent – sulfuric acid. The results of the work make it possible to reduce the duration of fatty acids obtaining from soapstocks, since the efficiency of the process with the minimum duration of mass settling has been confirmed. The improved technology of soapstock decomposition makes it possible to obtain a valuable product – high-quality fatty acids under rational conditions.
