Sažetak
U radu su okarakterizirana četiri uzorka nafti: domaća nafta i nafta REB (Russian export blend) koje se prerađuju u Rafineriji nafte Sisak, nafta Siberian Light koja se prerađuje u Rafineriji nafte Rijeka te nafta REB Odessa, Ukrajina, kao potencijalna nafta za preradu u RN Rijeka. Atmosferska i vakuum destilacija uzoraka nafti provedene su po ASTM D 2892 i ASTM D 5236 metodi.
Dobiven je niz podataka o fizikalnim i kemijskim svojstvima uzoraka nafti, destilaciji pravog vrelišta te iskorištenju i karakteristikama frakcija koje daju dovoljno informacija koje se mogu korisno upotrijebiti kod vrednovanja nafti (npr. izrada crude oil assay) i izbora preradbenih shema.Abstract
Characterisation of the four crude oil samples has been described in the paper: Croatian crude oil, REB (Russian export blend) crude oil processed at Sisak Oil Refinery, Siberian Light crude oil processed at Rijeka Oil Refinery, and potential REB Odessa crude oil. Atmospheric and vacuum distillations have been performed on the basis of ASTM D 2892 method for distillation of crude oil and its products, as well as on to the ASTM D 5236 method.
A series of data obtained on physical and chemical properties, true boiling point distillation, as well as utilisation and characteristics of fractions, provide enough information to be used in evaluation of crude oils (i.e. preparation of crude oil assay) and selection of process diagrams
