ABSTRACT
The necessity of emulsion breaking (demulsification) is recognized across various fields, including the petroleum industry, paint manufacturing, and environmental wastewater treatment. Chemical demulsification, the most prevalent method employed for water-in-crude oil emulsions, utilizes specific chemical additives to expedite the separation process. This study investigates the impact of various demulsifiers on the stability and properties of these emulsions. Commercially available demulsifiers, categorized as Amine, Polyhydric Alcohol, Acid, and Polymeric, were tested on water-in-oil (w/o) samples. The results revealed a strong correlation between rapid droplet coalescence (considered good performance) and the specific type of demulsifier. Beaker tests were conducted to assess the relative water separation rates, with Amine demulsifiers demonstrating the most effective droplet coalescence. Conversely, Polymeric demulsifiers displayed the least efficient water separation.
The ever-changing nature of crude oil emulsions throughout the depletion of production fields presents a significant challenge for designing and operating oil-water treatment equipment. These continuous variations necessitate future performance considerations when designing treatment systems. Understanding the concepts of scaling and upscaling is crucial when addressing these changing conditions.
This research delves into the theoretical and technological aspects of crude oil and water treatment. It begins by exploring emulsion formation theories, examining their stabilization mechanisms, and delving into the techniques used to stabilize and separate water from dehydrated oil. Subsequently, the research will analyze desalting technologies for achieving the desired oil specifications.
