Abstract
U radu su analizirani uzorci domaće nafte Slavonija i Moslavina te uzorak plinskog kondenzata koji se koriste u preradi u RN Sisak. Određene su fizikalno-kemijske karakteristike uzorkovanih nafti, plinskog kondenzata i njihovih frakcija te je načinjena atmosferska i vakuum destilacija pri čemu su korištene ASTM D 2892 i ASTM D 5236 metode.
Dobiveni podaci predstavljaju fizikalno-kemijsku evaluaciju nafti u laboratorijskim uvjetima iz kojih proizlaze baze podataka o naftama (eng. crude oil assay-i). Navedeni podaci koriste se pri optimiranju prerade RN Sisak pomoću matematičkih modela. Ukazano je na vrijednost domaćih nafti kao kvalitetne nisko sumporne sirovine.
Iz uspoređenih krivulja destilacije, gustoće i sumpora domaćih nafti i plinskog kondenzata rađenih kroz period od 30-tak godina, zaključeno je da nije došlo do značajnih promjena u sastavu nafti i plinskog kondenzata.The work comprises processing of the Slavonija and Moslavina crude oil and gas condensate samples used in the Sisak Refinery production. The physical and chemical characteristics of crude oils, gas condensate and their fractions were determined. Laboratory distillation was carried out in accordance with ASTM D 2892 and ASTM D 5236.
The obtained data are used for preparation of crude oil assays, e.g. for optimisation of atmosphere and vacuum distillations in the Sisak Refinery production by mathematics models. It’s pointed out of value of domestic oils as high-quality low sulphur feeds.
From the distillation curves, density and sulphur curves from domestic oils and gas condensate made over a period of thirty years it was concluded that there haven’t been significant changes in the composition of oil and gas condensate
