Summary: In petroleum industry process like drilling, exploatation
andpreparation of oil for transportation, effluent containment withsolid
particles, oil and various dissolved matters is anobligatory product.
Before it is being disposed off, the effluentis usually refined in order ro
return some of it along with somesilt back for further use. Also the bulk
of disposed effluent isthus reduced to a minimum.
This paper presents various methods for effluent refinery rangingfrom
simple ones in which settling basins are used to those withcentrifugal
separators and/or application of flotation method.

Summary: The paper gives an overview not only of the
mechanismsresponsible for hydrocarbon expansion into soil but also
thepossible simple methods for evaluation of the proportions ofpollution
involved, as well as the primary actions to be takenfor revitalization of
the soil on destroyed Croatian oilfields.These actions should come into
force as soon as possible, since,it will take several years and more before
the damage iscompletely removed and the soil restored.

Summary: In the article the relationship between system of technical
andsystem of social norms in ecological project has been consideredfrom
constructivist standpoint in sociology of technology. Foradequate solution
of technological problem of environmentalpollution by hydrocarbons is
necessary to define beside technicalalso system of social norms.
Sociological analysis of accidentsin transportation of hydrocarbons is
suggested in purpose ofclear definition of responsibilities of certain
social actors andfor modification of existing laws for environmental
protection.

Summary: From the aspect of the social construction of tehnology
theory a specific and relatively rare, but unaviodable phenomena of
technological accidents are analyzed. For this type of approach is
characteristic thesis of technlogy as social and cultural construct which
meaning is given by social and cultural situation of the group. There are
three phases of research program of social construction of technology: 1.
discovering interpretative flexibility of artifacts, 2. closure and
stabilization of technological solution, 3. embedments in wider social
context. Accidents are investigated in this model showing interpretative
flexibility, i.e. accidents are normal part of every technological system
and are the result of complexity of the system because of which multiple
failures are present.

Summary: The paper presents the mathematical model of hydrophobic
matters spreading across the surface as well as their infiltration into the
soil. The paper shows by experiments the proved justification and
application of the presented model based on spherical shapes characteristic
of hydrophobic matters. It is possible to determine their forms by means of
an iterative procedure at any instant of polluting agent spreading and thus
compute the size of polluted area as well as depth of infiltration.

Summary: Recycling is a technical process for the separation of
usable constituennts from waste material with the aim to increase their
marketing value.
Community waste is a specific kind od waste due to its marked inhomogenity
and the small marketing value of the constituents. Therefore, such a waste
is deposited or burned, sometimes previously recycled, usually before
burning. By recycling the heating value of the waste increases and the
amount of ash, slag, and reject gases decreases, so the total mass of waste
to be discarded can significantly be reduced. The recycling process
includes a rather extensive amount of operations - crushing, sizing, and
sorting being the most important.
In the paper the devices used in the mentioned operations are described,
sorting results are quoted, and flowsheets for three variants of recycling
processes are given, with the basic indicators of their efficacity.

Summary: The authors have developed and elaborated a new method of
measuring the intensity of soil pollution with oil, considering specific
conditions under which the process of pollution production, collection and
transportation of hydrocarbons take place in so called small oil fields.
Experimental research in dry and soil-saturated soil samples leads to the
discovery of a new methodology that enables very simple experiments in
field and laboratory conditions. On the basis of ten equations obtained by
this methodology, it is possible zo get desirable pollution quickly and
easily.

used in the two biggest ex-Yugoslav alumina plants are shown. One plant is
situated at Zvornik/Bosnia and the other at Mostar/Herzegovina. The
presumable detrimental impact of these depositories on the environment are
considered as well as the anticipated protective measures.

Summary: The most objections against coal as a fuel are related to
emissions of dust, slag, ash and SO2 and NOx components. A decrease in the
emissions of these pollutants can be achived by coal benefication,
aplication of new combustion techniques and cleaning of flue gases. The
flying dust is eliminated by electrostatic precipitators and bag filters,
the SO2 compounds by dry and wet adsorption methods and the NOx components
by selective resp. nonselective catalytic reduction.
In the paper the methods developed during the last years are presented,
with some of them still in a test stage. One is a NOXSO process, where for
the elimination of SO2 and NOx compounds an adsorbent on alumina basis is
used, whilst in an other method for the elimination of SO2 and CO2 an
aerogel of a large specific surface is used. In the SNOX process, developed
in Denmark, NOx is eliminated by selective catalytic reduction and the SO2
is used in the fabrication of sulphuric acid. Aplicating these processes it
is possible to remove 90 to 97% of SO2 and 70 to 95% of NOx while the
emission of flying ash can amount to 1 mg/m3 gas.

Summary: Reclamation of open-pits, tailing sites, neutralizing af
acid mine water ond protection against spontaneous coal combustion are
carried out very succesfully nowadays. New mineral processing technologies
make possible considerable reduction of ash and sulphur content in coal.
The application of the so called "clean" combustion technologies helps
reduction of solid refuse mass and gaseous pollutants emission. The
protection measures used in single exploitation stages and the most
promissing technologies of coal processing and combusting are presented.

Summary: Due to possible extent of the pollution by hydrocarbons in
oilfields, a simple prognosing method is proposed in order toestimate the
spread and depth of pollutant penetration into soiland eventually into
groundwater. The suggested method can besimple applied on oil fields,
because it does not require acomplex and expensive equipment. The
interpretation of obtainedresults is simple as well. It has been proved by
laboratorytests, that the results can be achieved in a very simple
waysatisfying by their accuracy in comparison with other inliterature known
mwthods which are considerably more complex andexpensive.

Summary: Two methods of the transport of the pollution in saturated
porousmedia are analyzed: finite element method and random walk
method.Computer programs are made for both methods. The programs arewritten
in MS FORTRAN 5.0 and installed on PC AT. Programssimulate a transport of
tracer in stationary plane flow ofgroundwater. It is understood that the
process of the flow isresolved prior to the transport and it is necessary
to know thepiezometer head in the proper points of the region.
