One of the largest wastewater flows generated in the oil and gas industry is produced water
(PW), which can come from oil fields, gas fields or a combination of oil and gas fields. This …

Naphthenic acids are comprised of a large collection of saturated aliphatic and alicyclic
carboxylic acids found in hydrocarbon deposits (petroleum, oil sands bitumen, and crude …

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 …

Canada's oil sands industry uses large volumes of freshwater to extract bitumen from
surface-mined ore. With oil production expected to increase 3-fold over the next decade …

The removal of water-soluble organics compounds in oilfield produced water (OPW) is
currently one of the biggest challenges to meet the environmental legislation, as …

In this study, N-alkyl imidazolium ionic liquids with highly alkaline phenolate anions were
used for the removal of naphthenic acid from model acid oil. The effect of alkyl spacer length …

Naphthenic acid removal from bitumen-derived HVGO by thermal cracking and catalytic
decarboxylation was investigated over alkaline earth-metal oxides and ZnO catalysts in a …

This study reports the adsorption of the naphthenic acids (NA) presents in an aviation
kerosene (AVK) model mix using adsorbents prepared from peanut shell (PS). Both …

The isolation and recovery of naphthenic acid from highly acidic model oil was performed
using hydroxide-based ionic liquids. An extremely low ionic liquid/oil ratio was used to …

Sorption of acetic acid from ethyl acetate and ethanol (95%) has been investigated using
polymeric ion-exchange resins with a view for being possibly applied to the removal of …
