Abstract

One of the most important problems associated with oil production is the formation of stable (water-in-oil) emulsions, and these emulsions greatly affect the process of treating the oil and ridding it of water.The creation of these emulsions throughout the oil production process is an expensive state, and the low water level of crude oil emulsions enhances performance while lowering the risk of equipment and pipeline deterioration. One technique to lower the water content is to break down crude oil emulsions chemically by demulsification. The water droplets quickly collide because the emulsifier renders the thin film separating the water droplets and the crude oil emulsion fragile. The current research includes the synthesis and characterization of novel demulsifiers for acrylamide based on Schiff bases and polyvinyl alcohol, which are both beneficial to the environment and highly effective in comparison to imported emulsifiers from other countries. Due to the application of highly hazardous industrial emulsifiers, new ecologically friendly demulsifiers were developed in this study that help reduce river water pollution. Employing nuclear magnetic resonance and infrared spectroscopy, the produced compounds were investigated. All of the polymer's spectrum signals corresponded well with the compounds' chemical structures. The photodegradation of the emulsions used was also studied and it was found that they are characterized by high disintegration and have the ability to reduce surface tensions. The thermal stability of the prepared compounds was also measured.
