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.

Functional materials for medical and biological purposes on he system CaO-CaF2-P2O5-H2O and additives
(Scientific and Technological Corporation "Institute for Single Crystals", 2018) Krivileva, S. P.; Moiseev, V.
The system of CaO-P2O5 has been studied, he polymorphism of Ca3(PO4)2 has been verified, he position of binary eutectics and the melting points in them on he Ca3(PO4)2-Ca4P2O9 segment have been determined. A diagram of the state of the CaO-P2O5 system is constructed. The experimental verification of the calculated data by the high-temperature microscopy method in sity is performed. The regions of primary crystallization of phases in the system Ca3(PO4)2-CaCO3-Ca(OH)2-H2O are refined. The subsolidus structure of the systems CaO-CaF2-P2O5-H2O and CaO-MgO-CaF2-P2O5 has been studied. The areas promising for the synthesis of materials based on CaO-P2O5-CaF2-H2O system and additives for the reconstruction of structural defects of the skeleton are established.
Functional hybrid organo-inorganic composite materials of the incorporative type for the recovery of articular cartilage defects
(Institute for Single Crystals, 2019) Krivileva, S. P.; Rassokha, A.; Zakovorotniy, A.; Moiseev, V.; Zhukov, V.
The concept of obtaining a functional hybrid organo-inorganic composite material of the incorporation type with a binder based on polyacrylic acid and a nanocrystalline filler of a frag- mentary structure has been developed. Ca3(PO4)2 particles contain two phases with a semicohe-rent boundary between them. Structuring of the composite takes place at five levels: in the volume of the polymer binder, in the interfacial layer and the polymer matrix adjacent to it, and in the outer and inner layers of the calcium phosphate filler. The effects of composition, structure, and the ratio of the initial components on the properties of the composite were studied. The use of the composite causes the growth of young tissue of the articular cartilage with the restoration of its structures.
Automating the process of calculating the singular points and modeling the phase diagrams of multicomponent oxide systems
(Institute for Single Crystals, 2019) Krivileva, S. P.; Zakovorotniy, A.; Moiseev, V.; Ponomareva, N.; Zinchenko, O.
To automate the processes of calculating elements of state diagrams of multicomponent eutectic type oxide systems and simulate them, a calculation algorithm and an application package using function libraries has been developed. On the example of binary and ternary systems FeO-Cr2O3-SiO2, BeO-MgO-TiO2, BeO-MgO-ZrO2, Ca3(PO4)2-CaF2, their functionality was tested. The experimental verification of the compositions of singular points (binary and triple eutectics and van Rijn points) and melting temperatures in them by high temperature microscope in situ has shown good correlation between the experimental and calculated data.
Evaluation of the possibility of using nanocrystalline apatite powders as inorganic fillers of toothpastes
(НТУ "ХПІ", 2018) Krivileva, S. P.
The article describes the most common types of toothpastes and materials used as inorganic abrasive polishing fillers therapeutic toothpastes available on the market. The prospects of using in the composition of therapeutic toothpastes and dentifrices for the teeth and mouth cavity of powders based on hydroxyapatite are evaluated. It is shown that in the products available on the market used biogenic hydroxyapatite submitted either in an inactive form, or containing deproteinized bone fish or farm animals (pigs or cattle). The prospects for the use of synthetic nanocrystalline apatite powder, purposefully developed for the plasticity of skeletal defects, in the composition of toothpastes and in dentifrice products – to replace inorganic components in their composition, consisting of chalk, kaolin, soda (in the lower price segment), is shown titanium dioxide or aerosil (in the upper price range), or biogenic hydroxylapatite (as part of innovative premium products), traditionally used as abrasive components.
Decreasing of threats to the condition of environment of Turkmenistan at the hydrocarbon and mineral raw materials mining
(NTU "KhPI", 2017) Ginkul, A. P.; Krivileva, S. P.
The main ecological problems of Turkmenistan caused by the use of environmentally hazardous methods of exploration and production of hydrocarbon and mineral raw materials are analyzed. The main methods used in Turkmenistan for the extraction and transportation of oil and gas and the environmental consequences of their use are listed. The main causes of the deterioration of the natural environment of Turkmenistan during the extraction of hydrocarbons on the shelf of the Caspian Sea have been identified. Technological innovation in the exploration and production sector has equipped the industry with the equipment and practices necessary to continually increase the production of natural gas to meet rising demand. Hense formulated the prior areas for further rising of environmental safety in the oil and gas sector and extraction of mineral raw materials: wide introduction into the production of new innovative energy-efficient technologies and the latest achievements of the world science in the entire production cycle - from geologic explorations, development and development of production to transportation, storage and use of natural resources.
