Development, improvement, management and estimation environmental sustainability and safety of industrial territorial entities as systems with closed loops

Зовнішній вигляд поверхні пакета труб після застосування тимчасового протикорозійного захисту і не упакованого металу

The techniques of complex assessment of resource efficiency, impact on environment and safety of different scale objects and systems are developed for effective decision making and management. Indicators for environmental component assessment of sustainable development of the regions of Ukraine and their vulnerability to environmental threats are proposed including resource efficiency and carbon intensity criteria. Complex analysis of environmental component is carried out in sustainable development dimensions for regions and macroregions of Ukraine.

Geotechnical complex with intellectual adaptive device of impuls action for executive rocks and extraction minerals

Лабораторний зразок мультиплікатора тиску

The process of the pulse of rock destruction is carried out with the adaptation of the parameters of the face, the adaptation is achieved by selecting the number and location of the mass of the impactor changes in the active sites of power elements, increase low frequency pressure in the hydraulic drive, automated control of hydraulically geotechnical complex, allowing for 10 ... 15% increase efficiency pulse break the rock.

Development of resource-saving technologies of recycling of domestic non-woody plant material in cellulose containing production

вибілена целюлоза із соломи

The resource-saving and ecologically cleaner technologies of obtaining pulp from the stems of agricultural plants were developed. Chemical composition and microscopic structure of representatives of Ukrainian plants were identified. Influence of basic technological parameters of obtained pulp by different methods of delignification on their indexes of quality. New methodology of efficiency comparison of domestic non-woody plant materials delignification processes is offered.

The elaboration organosolvent methods of obtaining and using the pulp from the agricultural plants in pulp and paper industry

Зразки недеревинної сировини

Fractional and chemical composition, microscopic structure of various representatives of non- wood plant Ukrainian material was investigated. The necessity of using new crops for obtaining fibrous semi-finished products for needs of pulp and paper industry was well-founded. The influence of main technological factors (temperature, duration, consumption of basic chemicals) of obtaining fibrous semi-finished products to their physical and mechanical performance was investigated.

Ecologically safe complex impulse and wave action for development deposit and extraction mineral

Created and introduced a theory, applied in practice of impulse and wave destruction and also system of adaptive management of process of impuls and wave destruction of rocks. On the basis of the applied theory are developed new executive powers of impulse and wave action and technology with use of the given theory.

Corrosion protection of steel in condition of the operation of new energy-saving generators - contact water heaters

Установка для магнієвого захисту в діючій котельні

The electrochemical behavior of steel in a model of contact water heating was investigated. It was shown that the increase in temperature, carbon dioxide concentration, the application of stirring lead to an increase in corrosion rate, which is not inhibited in time unlike corrosion in the water with natural CO2 content. The dependence of pH on the concentration of CO2 was established, which is the main corrosion factor.

The elaboration resourse saving ecology safe technologies of processing of vegetal raw material stems in confumer goods

Фото мікрокристалічної целюлози

Chemical composition and microscopic structure of stems of representatives of non-wood plant raw material were established, which allowed to prove the feasibility of processing them into production of pulp and paper, pharmaceutical and woodworking industries. Influence of main technological parameters (concentration, temperature and chemicals consumption) of obtaining pulp on quality indexes (yield, content of residual lignin, physical and mechanical properties) was studied. This allowed calculating adequate regression equations using mathematical methods of planning experiment.
