چکیده

در این پژوهش، نانوذرات مغناطیسی Fe3O4 سنتز شد و ویژگی­های آنها با میکروسکوپ الکترونی روبشی گسیل میدانی (FESEM)، پراش سنج پرتوی ایکس (XRD)، طیف­سنج تبدیل فوریه فروسرخ (FT-IR) و مغناطیس سنج نمونه ارتعاشی (VSM) بررسی گردید. افزون بر این، عملکرد نانوذراتFe3O4  به همراه روکنشگر تالو آمین اتوکسیله (TAE) در تعلیق­زدایی نفت خام با آزمایش بطری ارزیابی شد. ترکیب نانوذرات Fe3O4 و TAE بازده جدایش آب از نفت را تا ۹۴ درصد بهبود بخشیده و مصرف تعلیق شکن تجاری را کاهش می­دهد.

چکیده [English]

In this study, MNPs-Fe3O4 were synthesized, and the properties of these nanoparticles were investigated by FESEM, XRD, FT-IR and VSM. In addition, the performance of MNPs-Fe3O4 along with ethoxylated tallow amine (TAE) surfactant in crude oil demulsification was evaluated by bottle test. The combination of MNPs-Fe3O4 and TAE improves the efficiency of water separation from oil by 94% and reduces the consumption of commercial demulsifier.
