Electrostatic Field - an overview | ScienceDirect Topics

Darren Ashby, in Electrical Engineering 101 (Third Edition), 2012. The Electric Field. Also called the electrostatic field, the electric field 36 is not as commonly known per se as the magnetic field. In the same way that current is connected to the magnetic field, voltage is connected to the electric field.

01-05-2007· When a liquid mixture is subjected to external electric fields, ionic screening leads to field gradients. We point out that, if the mixture is initially in the homogeneous phase, this screening can bring about a robust phase-separation transition with two main features: (i) the phase separation is expected to occur in any electrode geometry, and (ii) the voltage required is typically of the ...

Electrostatic separation | CTP

Electrostatic separation. Electrostatic separation techniques exploit the electrical conductivity differences of particles after charging and the appearance of positive or negative charges on their surface. The method of charging varies depending on the equipment and the application. A system of attraction or repulsion proportional to this charge enables their separation.

Electrostatic Separation Procedure

Separation of minerals utilizing differences in their electrical properties may be carried out using an electrostatic separator. It will separate electrical conductors (minerals such as cassiterite and rutile) from those that are electrical non-conductors (minerals such as zircon and siderite). The principle of separation is that as the particles to be treated are passed through an intense ...

Electrostatic Separation - Mine Engineer.Com

ELECTROSTATIC SEPARATION is defined as "the selective sorting of solid species by means of utilizing forces acting on charged or polarized bodies in an electric field. Separation is effected by adjusting the electric and coacting forces, such as gravity or centrifugal force, and the different trajectories at some predetermined time.

Electrostatic treater - OilfieldWiki

Electrostatic treaters are used in the oil/gas industry to help facilitate oil/water separation by breaking emulsions by applying electrical charges. Electrostatic treaters are similar to horizontal heater treaters in design and operation. The main difference between the two units is the electric coalescing section in the electrostatic treater which replaces the hay section in the heater treater.
