Reply to "electrostatic oil cleaning system"

Electrostatic cleaning is STATIC, meaning that the main characteristic is ZERO current, and a high voltage.

Electrolytic is characterised by high current and low voltages (comparativley) There is a high energy input to break down the ionic components, and this is reflected by a high current, the product Volts x Amps is very high, reflected by large scale transport of ions to their preferred electrodes.The current is by a dissociation of ions, and this consumes high energy.

The electrostatic cleaners have transformers which cannot provide this high energy, they are only potential transformers.. if a current builds up, the voltage will drop drastically and the transformer will trip on a safety device. So, to carry on with your salt example, the electrostatic field will carry a particle of salt to the collectors, it just cannot provide the energy to break it up into sodium and chlorine ions and carry these ions to the electrodes. The product Volts x Amps is zero as current is zero.

Just look at the other common use of this technology - electrostatic precipitators for flue gases from chimneys, they simply drop out the soot particles, the flue gas outlet is not chemically affected....otherwise the high temperature and high energy conditions are ripe incubators for dissociating oxides in the flue gase.But here again energy input from the electrostatic device is just not sufficient to cause any dissciation of oxides in flue gases..

I hope this makes the difference in Electrostatic and Electrolytic clear..

The static process just provides a field condition to separate out particles which tend to stick to "collector" media provided between the electrodes.like a balloon rubbed on a silk cloth will stick to a wall, or a pieces of paper will stick to a comb when you rub it on dry hair.

Viscosity of oil is changed only if two oils are mixed, or temporarily by temperature. The thinnig that you may have heard about is probably removal of sludge or polymerised matter which makes the oil appear clearer and lighter. Measured viscosity will not change by electrostatic cleaning.

Thanks Mukesh for clarification for Electrostatic and Electrolytic status of salts. Could you please clarify how electostatic cleaning will not be considered as Electrolytic ?
When NaCl is dissolved in water and currant is passed through the solution, NaCl is sepeared out by chemical reaction then why not other salts ( Additives which are similar metallic salts !! ) in similar way ?
Can you clarify the differance between Electrostatic and Electro Lytic solutions ? What is the differance ?

On One hand you say that soluble Additives in the form of salts are there in the oil and oil is chatged with electricity then when you pass electric currant through it why these salts will not be affected ?

I have learned from many users of electrostatic cleaners, that Oil is loosing it viscosity and it becomes thin, could it be because of depleation of any viscosity Index improver ?

The process is Electro STATIC not ElectroLYTIC. Hence dissolved components cannot be affected. In a static field salt will not separate out of water, for instance.

Only particles, being separate from the oil, will be separated out. There is a wealth of trial evidence to prove that dissolved additives cannot be removed. Only "foreign" particles are removed.
