Aplicación de conceptos clásicos de la Física en la práctica ingenieril. La ley de Stokes como herramienta conceptual en el análisis de procesos de deshidratación del petróleo

AbstractSeveral physical processes have been used in breaking of water-in-crude oil emulsions (petroleum dehydration); heating, water and diluents addition and electrical field application are the most common ones. In all cases, the effect of each operational parameter on the main variables that determine sedimentation rate of water droplets in emulsions can be predicted by Stokes’ Law, which constitutes a simple mathematical expression very useful for chemical engineers in design and operation of separation processes of emulsified systems
