RESUMO

The present work approaches aspects of oily water treatment, by using hydrocyclones, in a petroleum primary processing plant. It shows the hydrocyclone, its utilization in the petroleum industry and the flow phenomena occurring within it. Starting from the mass conservation and linear momentum conservation equations, assuming some hypothesis, one writes a differential equation for the stream function that, after some work, provides a set of equations suited to use as a model for calculating the hydrocyclone separation efficiency. Some causes of the deforming and break-up of droplets are studied. Afterwards, it is investigated which of these causes apply to the flow inside of the hydrocyclone and, finally, a simple model representative of the droplet break-up phenomenon is developed. A new separation efficiency is calculated, considering the droplet break-up phenomenon. All the computational modeling was done using software MATLAB.
