Wax can increase the viscosity of waxy crude oil, also precipitates and accumulates on the pipe wall, reducing the efficiency of pipe transportation. A strain of surfactant producing hydrocarbon degrading bacteria F-1 was isolated from crude oil…
A better understanding of the nature of crude oil compounds that preferentially interact with certain types of solids is essential to visualize solutions to challenges in oil fields, such as enhancing the oil recovery factor, via wettability…
Abstract: The paper describes an investigation of structural and geochemical properties of genetically similar crude oils from the Turija-sever field located in the South-Eastern Pannonian Basin, Serbia. Samples from 56 wells were examined by…
The present work concerns the study of rich laminar premixed CH4/C2H6/C3H8/O2/N2 flames operating at two equivalence ratios ( = 1.66 and 2.05) and low pressure (80 Torr). In the case of the flame = 2.05, the influence of pressure was studied between…
Oil-dispersed -Fe2O3 nanocatalysts were prepared by coating -Fe2O3 nanoparticles with oleic acid (OA). Mossbauer spectroscopy, X-ray diffraction, and field emission scanning electron microscopy were used to characterize -Fe2O3 and -Fe2O3@OA. Their…
Given the ill-defined term “naphthenic acids” (NAs), we will classify NAs as the carboxylic acids found naturally in crude oil, which include both classic NAs (c-NAs, monoacids) and ox-NAs (polyacids). Resulting from the biodegradation mainly of…
