Unconventional crude oil extraction, transportation, and downstream refining have encountered a huge formation of petroleum emulsion (or rag layer), which causes serious problems such as equipment corrosion, loss of crude oil, and catalyst poisoning.…
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…

This work aims to evaluate the use of petroleum as a solvent in the liquid-liquid extraction of oil and grease content from oilfied produced water. Initially, tests were performed with synthetic effluent, using cyclohexanecarboxylic acid as model…

There is an increasing interest in treatment of oil sands process water (OSPW) via biofiltration with petroleum coke (PC) as a substratum. In fixed bed biofilters (FBBs) with PC, the dominance of anaerobic digestion of dissolved organics results in…

Propelled by enormous increase in demand for fuel sources, Canadian oil sands are becoming increasingly important as a fuel source due to their abundance and upgrading capability. However, extraction of bitumen, a high acid crude (HAC) oil, requires…
Crude oils due to its profuse chemical composition produce complex dispersion and emulsion flow behavior with water. The interfacial properties and surface chemistry of oil and water influence heavily the stability, flow behavior and separation of…
During the crude oil refining process, the piping system suffers a lot of corrosion damage at the elbows due to complex chemical reactions. This work aimed to investigate the effects of sodium chloride (NaCl), calcium chloride (CaCl2), naphthenic…
