Quick increase of the scientific and technological revolution temps and
influence of human on the nature becomes more and more powerful each year. A
numerous toxic substances are emitted into the biosphere and that leads to
undesirable effects . Every year about 30 billion tons of fossil fuels are
extracted for satisfying of human needs, at the same time about 100-150 billion
tons of subsoil are moved. During the further recovery processes the substation
part of extracted fuels which are not the part of economic goods, becomes a
waste. Although in XX century the negative influence of the waste on biospherewas smoothed by nature processes, in last decades the size of human activity leads
to the edge of ecological disaster. One of the most polluting branches is
petrochemical industry. That’s why, the recovery of oil waste is one of the
most actual ecological problems Oil waste is one of the most dangerous
component of natural environment. Oil waste is a strong polydisperse system
that is formed as a product of oil, water and mechanical admixtures
interaction.
An oxidation of organic part of the waste by the oxygen of air and
catalityc action of metals of this oxidation have a great impact on the
formation of such system and lead to formation of resinous substances. The
average oil waste consists of oil component (35-45%), mechanical admixtures
(under 35%) and water (20-30%). The composition of oil waste may be various and
depends on place and period of its formation. This circumstance may strongly
complicate the problem of waste utilization. Considering all main world
tendencies in petrochemical industry, it should be mentioned that Ukrainian oil
refineries realize the closed cycle principle which means using waste as a raw
in technological process. For more.....
