Oil Regeneration System

UVR – 450/16

Extends oil life Saves money Environmentally friendly Extends transformers life Can be used for treatment of nearly all mineral oils Re-refined oil prices are competitive to equivalent virgin oil prices

Globe Core™ Oil Regeneration System is designed to remove solid particles, regenerate and lighten electric insulation, turbine, industrial*, mineral oils.

The most sophisticated to date oil reuse method is regeneration, defined by EEC Directive as “ any process whereby base oils can be produced by refining waste oils, in particular by removing the contaminants, oxidation products and additives contained therein”. Regeneration prolongs the life of the oil resource indefinitely. This form of recycling is the preferred option because it closes the recycling loop by reusing the oil to make the same product that it was when it started out and, therefore, uses less energy and less virgin oil. Regeneration of used oil takes only about one-third the energy of refining crude oil to sufficient quality.

The viscosity of the product must not exceed 70cSt at 50oC, with moisture content below 200g/ton. *- industrial oil can only be regenerated after preliminary removal of water, fluid, oxi-acids, carbenes and asphaltenes.

Regeneration Pods

Oil Regeneration System consists of upper and lower oil tanks, coarse and fine filters, adsorbent cartridges vacuum pump, heaters and instrumentation. The control panel contains vacuum and pressure gages, switches, indicating lights and temperature controller. Used, contaminated oil, fuel is drawn through coarse filter into the upper oil tank of regeneration system by means of an inlet pump. The liquid is then fed to the regeneration cartridges that rely on an adsorbent principle to restore acidity, interfacial tension, colour, resistivity and other parameters close to new oil or fuel conditions. Regenerated oil is accumulated in the lower oil tank and pumped out at the end of the process.

Vacuum chamber I – is a cylindrical vessel filled with regenerated oil. IN the top of the front bottom of the vessel, there is an inlet for regenerated oil, a level sensor of high oil level and an inlet for vacuum evacuation of the chamber. In the lower part of the back bottom, there is

flange for flushing of the vessel. The tank also features a liquid level indicator for visual control of the liquid level in the chamber.

Vacuum chamber II – is a cylindrical vessel filled with regenerated oil. IN the top of the front bottom of the vessel, there is an inlet for regenerated oil, a level sensor of high oil level and an inlet for vacuum evacuation of the chamber. In the lower part of the back bottom, there is flange for flushing of the vessel. The tank also features a liquid level indicator for visual control of the liquid level in the chamber.

Reservoir - is a cylindrical vessel, filled with contaminated oil. An inlet is welded into the vessel for connection with the atmosphere. There is an oil inlet and a level sensor welded into the front bottom, as well as a level indicator for visual control of the liquid level in the vessel. Contaminated oil outlet and a drain outlet are welded into the lower part of the vessel. The back bottom of the vessel is equipped with a connector for auxiliary unit.

Regeneration pod is a vessel, filled to the middle with regeneration media. Media and oil enter the pod through the upper lid.

The lower part of the pod consists of a metal sidewall an the lower lid, through which the pod is vacuumized. Also, regenerated oil exits the pod through the lower lid and spent sorbent media is extracted.

The external surface of the pod is wrapped with a strap heater, insulated and covered with a metal sidewall.

Collector is designed for removal of regenerated oil from the regeneration pods and is a pipeline with ball valves connecting the collector with regeneration pods; the side of the collector is equipped with a sight glass to determine the quality of regeneration, and two valves, switching oil flow to lower vessel I or II. The collector is also equipped with an inlet and a valve for connection of auxiliary unit. Oil input pump peripheral pump SAER KF-4, drive power 0.75 kW, 2850 RPM. Oil output pump is a peripheral pump KF-4, drive power 0.75 kW, 2850 RPM. Vacuum pumps create vacuum in the vacuum system, and are two vacuum pumps СР 10-520 at 0.75 kW. Pipelines connect all parts of the unit. Output filter is a case containing filtering element with magnets. Magnets can be cleaned when replacing the filter element (cartridge). Filtration fineness is 5 micron. The filtering element is covered with filter fabric. The lid is equipped with plug for release of air with oil enters the filter and air inlet when oil exits the filter. The bottom of the case is equipped with connector with valve. Oil inlet and outlet are welded into the case. Feed pipeline supplies oil into regeneration pod. The line is equipped with a float switch to prevent from pod overflow.

Filter 1 – oil inlet; 2 – clean oil outlet; 3 – contaminant drain outlet; 4 – filtering element; 5 – air release plug; 6 – magnets; 7 – pressing nut

Processed oil enters the top vessel through inlet valve MV1, coarse filter CF, pump P1, sight glass SG1, flow switch FS. The top vessel is filled with oil to the top level, after which the level sensor LS6 stops the pump P1.

Then vacuum pumps VP1 and VP2 should be engaged to create vacuum (-0.9…-1 bar) in the vacuum chamber 1 or 2. The vacuum in the vacuum chamber 1 and 2 is controlled by gauges M1 «VESSEL 1» and M2 «VESSEL 2».

From the top vessel, through valves MV3 – MV18 the oil enters regeneration pods, where it is purified and regenerated.

From there, the valves MV19 – MV34 on the collector are opened, the oil passes through regeneration media in the bottom of the regeneration pods, and enters the collector, from the collector the oil goes to vacuum chamber 1 or 2. The oil level in the lower vessel I or II is controlled by the level indicator welded into the sidewall of the vessel, and a level sensor.

The output pump P2 extracts the oil after regeneration from the lower vessel 1 or 2 and supplies it through the filter F, to unit output.
