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.

Multi-component wastewater from finely dispersed impurities treatment intensification
(Nicolaus Copernicus University, Poland, 2024) Bosiuk, Alona; Shkop, Andrii; Kulinich, Serhii; Samoilenko, Dmytro; Shestopalov, Oleksii; Tykhomyrova, Tetiana Sergiivna
The article deals with the intensification of flocculation wastewater treatment from finely dispersed suspended dust particles that are formed in the foundry shop at machine-building productions. The dependence of the floc sedimentation rate and wastewater clarification on solid phase concentration and flocculant flow rate was experimentally researched using model wastewater created by mixing dust and water. The multicomponent impurities of ionic flocculants on the aggregation process impact were experimentally proven, and anionic and cationic flocculants combination high efficiency was shown. The optimal parameters for the wastewater treatment process were established. The best flocculating effect and minimum flocculant consumption were observed at a solid phase concentration of 8-14 g/l. It was established that the most effective aggregate formation process is observed when two flocculants’ types are used simultaneously: anionic A-19 and cationic K-7, not each type separately. Flocculant flow rate experimental and calculated dependences for the wastewater treatment process depending on solid phase concentration and floc sedimentation speed necessary for effective sedimentation have been established. A technological scheme for wastewater treatment from suspended dust impurities that are formed in foundry shop at machine-building enterprise has been developed. The scheme includes: wastewater flocculation; water clarification in a sedimentation tank; and water deironing by aeration with coagulant addition and further filtration. It is proposed to use purified water in enterprise technological cycle that helps to reduce tap water consumption.
Studies of the physical, operational and optical-spectral characteristics of the highly transparent toluenesulfonamide and benzguanamineformaldehyde polymers

Environmental management implementation in wastewater treatment at a machine-building enterprise: from theory to practice
(EDP Sciences, 2023) Bosiuk, Alona; Filenko, Olesya; Shkop, Andrii; Kulinicn, Serhii; Tykhomyrova, Tetiana Sergiivna; Shestopalov, Oleksii
This study examines environmental management implementation in the context of wastewater treatment at machine-building enterprises. The article aims to assess how effectively environmental management is used in the wastewater treatment system to ensure rational resource use. It is noted that wastewater contains a significant amount of various pollutants that must be removed before disposal. A wastewater samples analysis was carried out to assess the environmental management implementation's effectiveness. The changes in the concentration of the pollutants during three months were found: the hydrogen indicator decreased from 7.83 mg/dm3 to 7.58 mg/dm3. The oil product concentration increased from 22.2 mg/dm3 to 3.4 mg/dm3, while the fat concentration remained stable. The received results provide important information for improving the wastewater treatment system and environmental management implementation. To ensure environmental safety and compliance with environmental standards, it is necessary to implement environmental management in wastewater treatment at machine-building enterprises. The optimal wastewater treatment technology choice and monitoring program development are described. The article contains practical recommendations for the implementation of environmental management at a machine-building enterprise and aperspective on this direction of development. The research is relevant and useful for machine-building complexes that have problems with wastewater treatment and aim to implement environmental management.
Design and Research of Environmentally Friendly Polymeric Materials Modificated by Derivatives of Coal
(VÚRUP, 2023) Lebedev, Vladimir Vladimirovich; Miroshnichenko, Denis Viktorovich; Tykhomyrova, Tetiana Sergiivna; Kariev, Artem; Zinchenko, Mariya; Bukatenko, Nataliia; Filenko, Olesia
The aim of the given work was to design new ecologically friendly polymer materials modified by derivatives of coal. An overview of the current trend in the development, production and application of efficient nvironmentally friendly polymer materials and composites is given. The main ways of hybrid modification of environmentally friendly polymeric composite for obtaining effective products based on them are presented. It is shown that it is promising to obtain environmentally friendly polymeric materials based on coffee waste using hybrid modifiers in the form of humic substances. Optimization studies have been conducted to determine the most effective composition of new environmentally friendly polymeric materials based on bioplastics "OK compost HOME" and coffee waste modified with humic substances. It was found that filling the bioplastic "OK compost HOME" with such coffee waste as coffee husk is more effective as with coffee grounds. It was found that the optimal content is 60 % mass coffee husk, that was modified by humic substances (2 % mass).
Sorption characteristics studies of eco-friendly polymer composites
(EDP Sciences, 2021) Lebedev, Vladimir; Tykhomyrova, Tetiana Sergiivna; Lytvynenko, Oleksandr; Grekova, Alla; Avina, Svitlana
This paper presents the results of new composite materials based on polylactide and coffee grounds sorption characteristics study. New material, that include coffee grounds as additive material is cheaper than one of common polylactide. All types of dishes cam be made from new material and they also will be biodegradable, as made from polylactide. The sorption properties and characteristics were tested in different liquid medium. The last was chosen among the most wide spread mediums which are contact with dishes during its operational life. It was found, that optimal content of coffee grounds is 40 wt.% as for level of impact strength also for complex of sorption characteristics
