Method and apparatus for promoting droplets coalescence in oil continuous emulsions
First Claim
1. An apparatus for a separation of a mixture of two liquids, comprising:
- a section configured to receive a mixture of two liquids;
a first flow conditioner section downstream of the section and comprising at least one first electrode for generating a first electric field and a first flow conditioner having a first permittivity;
a second flow conditioner section downstream of the first flow conditioner section and comprising at least one second electrode for generating a second electric field and a second flow conditioner having a second permittivity;
a permittivity measurement apparatus coupled to the first section and configured to measure the permittivity of the mixture;
a flow conditioner section selector configured to receive the mixture permittivity from the permittivity measurement apparatus and energize the at least one first electrode of the first flow conditioner section or energize the at least one second electrode of the second flow conditioner section based on a comparison between the mixture permittivity and the first permittivity and the mixture permittivity and the second permittivity.

Abstract
Separation apparatuses for the separation of a mixture of two fluids, such as a water-in-oil emulsion, via electrocoalescence, are provided. A separation apparatus may include a series of flow conditioners each having a different permittivity, such that the flow conditioner having a permittivity that is similar or equal to the permittivity of the flowing medium is selected. Another separation apparatus may include a flow conditioner having a frequency-dependent permittivity, such that the frequency of the electric field generated is selected so that the permittivity of the flow conditioner is as similar as possible to or equal to the permittivity of the flowing medium. Another separation apparatus may include a replaceable flow conditioner that may be replaced with a flow conditioner having a permittivity that is as similar to or equal to the permittivity of the flowing medium.
