Abstract

Uporaba raznih naftnih proizvoda danas je svakodnevica, no unatoč njihovoj velikoj
primjeni, eksploatacija, transport i preradba sirove nafte predstavlja potencijalnu opasnost za
okoliš. Rafinerije prilikom preradbe sirove nafte upravljaju ogromnim količinama sirovina i
proizvoda te su intenzivni potrošači energije i vode, koje se koriste za provođenje velikog
broja rafinerijskih procesa. Procesi odvajanja, preradbe i obrade sirove nafte su izraziti izvori
emisija u zrak, vodu i tlo, a među najvećim izvorima onečišćenja su procesi katalitičkog
krekiranja, hidrokrekiranja, koksiranja te hidrodesulfurizacije.
U ovom radu, naglasak je dan na emisije u vodu koje se javljaju u okviru rafinerijskog
postrojenja te na primjenu najbolje raspoloživih tehnika, s ciljem prevencije i kontrole
onečišćenja te obrade otpadnih voda u rafinerijama. Ukazan je doprinos integriranog vodenog
toka u rafinerijama, koji omogućuje ponovnu uporabu procesne vode, smanjenje emisija u
vode pri ispuštanju te ujedno i smanjenje operativnih troškova rafinerije.

Abstract (english)

Despite the big consumption of various petroleum products, the exploitation, transportation
and processing of crude oil presents a potential environmental risk. Refineries are industrial
sites that manage huge amounts of raw materials and products and are also intensive
consumers of energy and water. The separation process, processing and treatment of crude oil
are significant sources of emissions into air, water and soil, and among the largest sources of
pollution are catalytic cracking, hydrocracking, coking and hydrodesulphurization.
In this paper, the emphasis is given to water emissions that occur within the refinery and to
the application of the best available techniques for the prevention and control of pollution and
wastewater treatment. It was pointed out the integrated water flow in the refinery, which
allows reuse of process water, reduction of emissions to water as well as reduction of refinery
operational costs.
