Title: Removal Of Sulfides And Oil From Produced Water
Biography
Biography: Ana Karla Costa de Oliveira
Abstract
Produced water are complex mixtures which contain a large number of contaminants including finely dispersed oil, metals, and gases such as H2S and CO2, that are originated from oil and natural gas. In this paper we used solvent extraction to recover sulfides. We used three commercial amines belonging to the alkyl amine group as extractants, which were dissolved in aviation kerosene (JET FUEL). In this research real samples of produced water from the oil industry with initial concentration of 0.660 mg/L H2S were used. The parameters studied were: Amine/JET FUEL ratio (0.25 v/v) and organic/aqueous phase ratio (1/3 v/v). After the tests, it was concluded that the highest extraction efficiency occurred with the amine Duomeen which removed 76% of sulfides, followed by Arquad 2C-75, showing 59% removal efficiency and Duommen T which removed 40%.
