Vacuum Jet Dehydration Technology

Vacuum Jet Dehydration Technology has been invented by OilPure more than 25 years ago learning from the existing problems in Conventional Vacuum Distillation that can not ultimately solve water dehydration in oil. This Vacuum jet Dehydration technique has been a new theory of Non Vacuum for water removal in the oil.

Vacuum Jet Dehydration applies oil pressure at 70 psi and oil temperature at 140 °F mixing with atmospheric air to atomize through nozzle to create oil & water aerosol mixture, swinging through a cyclone separator.

The air/ oil mixing action forms the fluid mixture into aerosol as it enters the special design cyclonic separating tanks. At the right oil temperature any atmospheric air (even humid air) will increase its velocity while absorbing water from oil in the cyclonic separating tank. Water was previously in a liquid state, when it dissolves in the dirty oil. After the aerosol is mixed with air, water changes from liquid state to vapor state in the cyclonic separating tank. The cyclonic forced air will carry dissolved water to the upper steam and allow dried oil to fall to to the bottom.

Vacuum Jet Dehydration incorporates MS1 Moisture Sensor to control water dehydration process so water content from 2,000 – 10,000 ppm from incoming dirty oil will be removed down to 10-50 ppm before dried oil is discharged from Vacuum Jet Dehydrator.

Vacuum Jet Technology is capable of not only removing Dissolved Water, but also removes Dissolved Gases that have decomposed in the lubricating oils.

MS1 Moisture Sensor is controlling the water dehydration process to assure that the incoming 2,000 – 10,000 ppm of water will be removed down to 10-50 ppm before the dried oil is discharged from the dehydrator.

Water changes from Liquid Stage into Vapor Stage at 140 °F during dehydration. This process saves heating energy for water dehydrating process

Dissolved Gases such as CH4OH Methanol in Biodiesel, CH4 Methane, C2H2 Acetylene, H2S Hydrogen Sulfide, NH4 Ammonia, CO2 Carbon Dioxide etc. will be atomized and inflated with dissolved water, rising from oil in the cyclone separator. NH4 Ammonia dissolved gas in refrigeration oil can be degassed by Vacuum Jet Dehydration as

Advantages of Vacuum Jet Dehydration Technology over Conventional Vacuum Technology:

  1. Vacuum Jet Dehydration can remove water from high viscosity gear oil up to 600 ISO grade viscosity while Vacuum distillation barely handle ISO 220 oil viscosity grade. Very little amount of water can be pulled out so it has to heat the oil temperature to 170°F – 175 °F to get more water out but risking the built up of Oil Oxidation and oil breakdown.
  2. When water content is over 3% (30,000) ppm of water in the oil reservoir, there will be excessive oil foaming occurred in the oil reservoir. This foaming will escape into vacuum pump and condenser causing vacuum pump premature damages and repair. So Vacuum Switch is energized to reduce vacuum level from 21-24 Inch/Hg down to 16-18 Inch/Hg in order to bring down excessive foaming in the vacuum chamber. This causes inefficiency in water removal for Vacuum Distillation. Most of the time this doesn’t work.
  3. Vacuum Jet Technology is also capable of degassing the Dissolved Gases such as CH3OH Methanol in Biodiesel, CH4 Methane, C2H2 Acetylene and H2S Hydrogen Sulfide in Transformer oil. Vacuum Jet atomizes these Dissolved Gases as well as water which has similar affinity to be ejected from cyclonic separator.
  4. Vacuum Distillation also removes these Corrosive Dissolved Gases through vacuum pump and condenser, causing component corrosion and premature failure to a short life vacuum pump.
  5. Vacuum Jet Dehydration is low or no maintenance using positive displacement gear pump to increase oil pressure. This gear pump has a 5 year MTBF (Mean Time Between Failure). Vacuum Jet Dehydrator is designed to run on a non stop 24 hours/ 365 days basis. Nozzle eductor in Vacuum Jet is a self cleaning and will automatically clean itself every 20 cycles. Therefore, there is no oil line clogging for m
