“…Another application area of the sorbents saturated with petroleum products is their use as a part of a complex charge for the implementation of environmentally friendly processes for the restoration of domestic phosphorus by the natural gas in the presence of sodium sulfate [18]. Utilization of this waste can be carried out in the process of thermooxidation decomposition [19], the final product of which is a valuable raw material for the production of a number of building materials.…”

The effect of the content of natural and anthropogenic pollutants (potentially acidic organic substances, synthetic surfactants and petroleum products in water, which is exposed to desalting) on the efficiency of КU-2-8 ion exchangers has been studied. To minimize this negative influence the reagent method was used. Different natural and modified sorbents have been investigated for additional purification of water before filtration on cation-exchange filters or periodic regeneration of ion exchangers by the studied reagents.

“…Для промислового застосування наноструктур необхідною є оцінка технологічних та економічних критеріїв [23]. Крім того, все більше дослідників заявляють про ризики для навколишнього середовища, що виникають під час синтези й експлуатації нанотехнологічної продукції, а також шляхи зменшення неґативного впливу [24]. Тому необхідним є проведення комплексної оцінки наноматеріялів, яка має ґрунтуватися на системному підході та врахуванні всіх критеріїв якости наноструктур.…”

“…There are many modern technologies of utilization of different sorts of wastes [8][9][10] which allow to obtain raw materials for energy generation [11]. However, waste treatment in most cases is reduced down to waste dumping [12]. Since waste decomposition processes take place in limited periods on bounded territories, we observe high intensity of dangerous molecular compositions emission to the atmosphere [12] with the occurrence of unintentional fires [13,14], thus, investigations on the assessment of civil protection units' readiness to actions during extreme situations are taken [15,16].…”

To avoid dumping of wastes not suitable for recycling, the preferences must be given to high-temperature ways of waste disposal such as incineration, pyrolysis and gasification, because high-temperature waste disposal with the aim of obtaining energy that can be used is a promising and relevant direction.…”

Currently, there are existing technologies for high-temperature waste disposal, which use the resulting gas as fuel for recycling newly formed waste. However, the composition of waste is not constant, and contents of their components are different, thus, the need for fuel gas for burning is not stable. Therefore, such gas is constantly lost. Thus, the purpose of the article is to present the study results of the energy efficiency of high-temperature waste disposal technology, which includes low-temperature separation of the resulting gas mixtures, which allows accumulating fuel products. By means of numerical simulation an analysis of the functioning of energy-technological facility of separation of multicomponent hydrocarbon mixtures with the subsequent optimization of its parameters in order to improve its efficiency and decrease energy costs for waste gasification was performed. For this purpose, the classical approach and generally accepted thermodynamics relations were used, including the Peng-Robinson equation of state for the description of coefficients of heat-physical characteristics of working bodies. The complexity of calculation of multicomponent systems (with three and more components) does not allow application of the state diagrams. Thus, for the simulation of heat-physical characteristics the REFPROP program was employed. The energy efficiency of the proposed technology of energy resources production at waste utilization was shown. The amount of products obtained by the facility is equal to 5.242 kg/hour of the fuel product No. 1 with methane content of 99.98% and 54.76 kg/hour of the fuel product No. 2 with low quantity of methane. This confirms the economic efficiency of such technology of disposal.
