BORON TED IN PRE-AMORPHISED SI ROLE OF THE A/C

Following the Ostwald ripening theory, from the knowledge of the time evolution of the EOR mean size, it is possible to calculate the evolution of the self-interstitial supersaturation in equilibrium with the EOR during the steady state coarsening.

Hence, preventing asphaltene flocculation is preferable from both an operational and economical viewpoint. During oil production and transportation, the water and oil phases are co-produced, and thereby exposed to sufficient mixing energy to form dispersions of water droplets in oil and, conversely, oil droplets in the water.

2.2 Diffusional Degradation Besides coalescence, there is another mechanism by which emulsions degrade (or coarsen) into fewer, larger-sized droplets diffusional degradation. Monomer from smaller droplets diffuses to larger ones as the result of the process of interfacial free energy minimisation. This phenomenon is called Ostwald ripening (224).
