Growing problems of environmental protection related to the increasing soil degradation and increasing effects of climatic changes require searching for new, more efficient, and cheaper solutions that maintain relevant parameters of soil. One of the suggested solutions of present problems in the area of environmental protection is biochar, namely carbonate obtained from the plant biomass and organic waste pyrolysis. The use of biochar in environmental protection brings advantages, inter alia, such as a possibility...

Dust which comes from the flue gas purification in the process of thermal transformation of municipal wastes is classified as dangerous wastes. Their management poses a big problem. As a method of safe management, the dust may be used for the production of concrete as a partial replacement for the cement. By applying immobilization it is possible to reduce dangerous compounds and the material obtained becomes safe for the natural environment. Such a form of the dust application corresponds to modern waste manageme...

Water quality of the urban rivers become a critical issue in some regions of Russia including Kaliningrad region. Since the processes of development have affected already existing urban industrial sites in a number of cities in the region and lead to formation of the new, certain risks have arisen for rivers flowing through the territory of new industrial clusters. In this regard, it was estimated the ecological condition of the rivers in the area of industrial load on the following indicators: 1) assessing of the...

The relevance of the results. Significant natural resource potential of Russia requires its prudent use. At present, environmental management programmes have been adopted and are being implemented in most countries of the world.

The purpose of this study was to determine the effect of composted sewage sludge temperature (with the addition of structural material) on CO2 emission and the dynamics of th...

By adding H2 to CH4 the combustion characteristics improve considerably. The flammability characteristics of the CH4 are most well-known, but the CH4 enriched with H2 has a completely different behaviour regarding the flammability and the explosiveness. The understanding of the flammability of such mixture in the air is crucial to allow their safe use in industry. Lower and upper flammability limits are one of the most important parameters at the time of characterizing and handle flammable gases. This study is foc...

In-situ combustion is considered as one of the most effective ways to enhance recovery of heavy crude oils and bitumens. The oxygen from injected air reacts with the heavy components of the crude oil, forming a hot zone in which the cracking and oxidation of the heavy fractions occurs. It is noted that the combustion process essentially depends on the pressure and the nature of the crude oil. The effect of the oxygen content in the gas mixture on the combustion front propagation of heavy crude oils is shown. When ...

Animals have always accompanied man in specific activities, but also have provided the food supply through products of the livestock and food industries. Nutritionists remind us that we need meat, milk and eggs, as main products of livestock. Nowadays, the livestock sector is modernly equipped and it is coordinated by IT programs, which is why production can be anticipated, including risks. At the same time, modernity does not exclude the specificity of the place where livestock is concerned, to which the farmer i...

Hydraulic fracturing is one of the most widely and commonly applied production intensification method in the petroleum industry. The procedure?s main aim is to increase the contact area between the reservoir rock and the production system resulting in elevated productivity. In order to prevent the complete closure of the induced fractures the application of so-called proppant agents is obligatory. The size, shape, distribution and number of the proppants remained after the closure will affect the tortuosity and av...

Natural gas hydrate are solid compounds formed from water (host) and gas molecules (guest) at relatively high pressure and low temperatures. They are considered as a potential alternative energy source because of their high energy density, potential carbon-neutral nature and wide existence, both in permafrost and ocean seabeds. The most developed strategies for exploiting hydrate deposits are depressurization, thermal stimulation, chemical inhibitors and CO2 replacement. In particular, chemical inhibitors promote ...

The interruptions in electrical energy supply are unplanned events, determined by faults of the distribution network?s components, lightning strikes or unauthorized interventions in the distribution networks. Insulation faults, occurring in medium voltage networks, produce transient regimens with overvoltages/ overcurrents of very high values, produce large requests of network, switching equipments, generators and telecommunication systems. Because of this, the neutral point of the secondary transformer in the med...

D-glucose simultaneous catalytic hydro condensation with methylamine can beconsidered a promising way of methylglucamine synthesis. Amines such asmethylamine are reacted with materials such as reducing sugars in hydroxy solventssuch as methanol to prepare N-alkyl polyhydroxy amines. Accordingly, glucose isreacted with methylamine and the resulting adduct is hydrogenated to yield N-methylglucamine. The production of N-methylglucamine as early as 1935 was patentedby American scientists Robert B. Flint and Paul L. Sa...
