A large amount of impurities in the oil when it is produced makes price decrease. Therefore, necessary to demulsify stable emulsion which not separated from oil, so that impurity level becomes low. For this reason, required add a demulsifier increase water separation higher. Demulsifier highly influenced by temperature, salt content, mixture, and time. In study result yields highest d NaCl 60%+...

in this study, different methods of separating of the microalgae from the culture medium as one of the most important and expensive steps in achieving commercial production of biodiesel from microalgae was investigated. electro coagulation-flotation (ecf) was preferred among these methods due to its process simplicity and capability to scale up. the effect of three parameters, i.e., initial ph,...

In order to investigate the gas separation ability of a column packed with nanozeolitic material, nano NaY zeolite was synthesized and granulated. These uniform granules packed in a chromatographic column were utilized for separation of Xe and Kr under various operating conditions. With regards to the response peaks obtained from trace injections of Xe and Kr into the column, the first and seco...

1,3-Butadiene, BD is produced from C4-cut by extractive distillation. The separation of 1,3-Butadiene from C4-cut is not possible through the conventional distillation processes, because several mixtures have consisted of close boiling points constituents and make azeotrope. The BASF extraction distillation process in BD unit of Jam and Amirkabir Petrochemical Company improves the relative vola...

Abstract It is essential to know the process efficiency in industrial magnetic separation under different operating conditions because it required control parameters optimize efficiency. To our knowledge, there no information about using artificial intelligence for modeling process. Hence, finding a robust and more accurate estimation method predicting selectivity index still necessary. In this...
