Abstract

A heterogeneous spent soda effluent generated from Tunisian petroleum refineries has been filtrated and separated in four solid fractions with a particle diameter of 160 to 100, 100 to 40, 40 to 16 and 16 to 10?μm and the fifth one with diameters?<?10?μm obtained after total evaporation of the remained filtrate. Spectroscopic characterizations of the condensed phases by means of X-ray induced photoelectron and IR absorption, as well as pH-metry, potentiometry and stationary voltammetry at Ag₂S/Ag electrode studies of the filtrate, show that the whole of the separated fractions contain Na₂S, NaHS, C₂H₅SNa, Na₂S₂O₃, Na₂SO₃ and methyl, ethyl and propyl mercaptans.

突尼斯炼油厂苛性废水特性分析

对突尼斯炼油厂产生的异质废碱水废水进行过滤，分离成颗粒直径为160至100、100至40、40至16和16至10?第5个直径为?<?10?在剩余滤液全部蒸发后得到。利用x射线诱导光电子和红外吸收对浓缩相进行了光谱表征，并用Ag2S/Ag电极对滤液进行了ph法、电位法和固定伏安法的研究，结果表明，整个分离馏分中含有Na2S、NaHS、C2H5SNa、Na2S2O3、Na2SO3以及甲基、乙基和丙基硫醇。
