EXPERIMENTAL STUDY TO FIND ALTERNATIVE DEMULSIFIER TO TREAT EMULSION CRUDE OIL

Experimental Investigation of Polyvinylpyrrolidone for Application as a Demulsifier for Water-in-Oil Emulsion

Emulsification of produced immiscible mixed liquid of oil and water is a problem frequently recognized in surface production facilities in oil fields. The formed emulsions are required to be demulsified to avoid the negative consequences on piping and processing equipment. Nowadays, chemical demulsification is a preferable method to avoid or retard emulsification during the process of oil treat...

Optimization of Demulsifier Formulation for Separation of Water from Crude Oil Emulsions

In this study, various water-soluble and oil-soluble demulsifiers were selected for separation of water from crude oil emulsions and their productivity measured using the Bottle-test method at 70 °C and 10 ppm concentration. The best ones among 23 demulsifiers examined through the screening process were fatty alcohol ethoxylate, triethanol amine and urea from the water-soluble group and Basoror...

Emulsion Droplet Sizing Using Nmr: Application to Water-in-crude Oil Emulsions

Emulsion droplet sizing is an essential measurement requirement of a very broad range of industries including food, pharmaceuticals, personal care products, agrochemicals and crude oil dispersions. Nuclear magnetic resonance (NMR), courtesy of its ability to measure restricted self-diffusion via application of pulsed field magnetic field gradients (PFG), is able to readily measure emulsion drop...

Study on Viscoelastic Behaviors of Waxy Crude Water-in-Oil Emulsion

Emulsion of waxy crude oil is one of the common states in the subsea pipeline. At low temperatures in offshore environment, waxy crude oils with water could form the crude oil emulsion gel of oil-in-water emulsion. Thus, the waxy crude oil emulsion viscoelastic behavior for deep sea transportation and restarting pipeline safety is particularly important. By means of MASIII HAAKE rheometer which...
