Analiza softvera za projektovanje ESP sistema
Aleksandar Sredojević (2024)U momentu kada pritisak na dnu bušotine nije dovoljan da savlada ukupne gubitke pritisaka od dna bušotine do separatora, proizvodnja pomoću ležišne energije nije više moguća i bušotina prestaje sa eruptivnim radom. Kako bi ponovo omogućili proizvodnju fluida iz bušotine, potrebno je primeniti neke od mehaničkih metoda eksploatacije. Najprimenljivije mehaničke metode eksploatacije su: gas lift (GL), dubinske pumpe sa klipnim šipkama (SRP), električne uronjene centrifugalne pumpe (ESP), zavojne pumpe (PCP) i hidraulične pumpe (HP). Jadna od tih metoda koja ...električna centrifugalna pumpa (ESP), proizvodnja fluida, mehaničke metode eksploatacije, Prosper, Pipesim... motorno ulje nakon njegovog gašenja (Powers, W.J.). Gasni separator Osnovna funkcija gasnog separatora je da spreči ulazak slobodnog gasa u pumpu. Prisustvo slobodnog gasa na usisu pumpe predstavlja jedan od osnovnih problema za njen efikasan rad jer dovodi do smanjenja proizvodnje fluida i hlađenja ...
... otvorenog ili zatvorenog tipa. Gasni separator značajno poboljšava rad pumpe kada je prisustvo slobodnog gasa u bušotini iznad 25%. Hfikasnost savremenih gas separatora može iznositi i do 70% slobodnog gas na usisu. Izgled i delovi rotirajućeg gasnog separatora su prikazani na slici 4-10. Pored ...
... fluida Tačan proračun zapremine i vrste fluida na usisu u pumpu je veoma važan u dizajnu pumpe. Prisustvo i obim slobodnog gasa na ulazu pumpe mora se uzeti u obzir. Prisustvo slobodnog gasa može značajno smanjiti potreban pritisak pražnjenja, stoga može postojati potreba za koriščenjem gasnog separatora ...Aleksandar Sredojević.

Antioxidant and antimicrobial activity of some tetradentate Schiff bases and their Cu (II) complexes
Aleksandar Mijatović, Milan Nikolić, Snežana Spasić, Aleksandra N. Žerađanin, Kristina Joksimović, Aleksandar Lolić, Rada Baošić (2020)Šifove baze i njihovi Cu(II) kompleksi su poznati po svojoj biološkoj aktivnosti. U ovom radu proučavana je antibakterijska aktivnost protiv gram-negativnih sojeva Escherichia coli, Pseudomonas aeruginosa i Staphilococcus piogenes, kao i Gram-pozitivnih Staphilococcus piogenes i Pseudomonas aeruginosa, zajedno sa antifungalnim dejstvom protiv Musperg strainilusa, A. Takođe, tehnički jednostavni i brzi testovi kao što su ABTS, HORAC i ORAC korišćeni su za ispitivanje antioksidativne aktivnosti kako bi se uporedili dobijeni rezultati sa različitim tipovima testova. Uprkos tome što je princip ...Aleksandar Mijatović, Milan Nikolić, Snežana Spasić, Aleksandra N. Žerađanin, Kristina Joksimović, Aleksandar Lolić, Rada Baošić.
