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.
