The Low Vacuum Dehydration ( lvdh machine ) technique is mainly used for separating moisture content from the oil which is present in three forms:

a) Dissolved Form

b) Emulsified Form

C) Free form

Working Principle of Low Vacuum Dehydration machine : 

The heating of hydraulic oil is performed indirectly and then that is poured into a vacuum chamber where it is scattered into a very thin layer of film thereafter it vaporizes & gets dissolved with gases at low temperature. How do separate water from oil?

Now both air and gases that are derived from the previous process are now left to condense so that it gets separated from the oil.

Our ultimate goal of heating oil indirectly at low temperature is to ensure that there is no burn off hence no oxidation and no additional depletion of oil.

Comparative analysis of Vacuum Dehydration With Centrifugal water removals:

Centrifuging

Vacuum Dehydration

Heating oil to Approximately between 70 to 80°C is required to efficiently extract water

Whereas in LVDH technology, the Water is removed from oil even less than < 55°C.

Heating oil depletes additives.

No additive depletion.

Must be used off-line. All related machinery must be stopped to drain oil into barrels / tanks for cleaning.

Can be used on-line, is therefore user-friendly.

Somewhat cleans low molecular weight oxidized oil fraction

Easily removes low molecular weight oxidized oil fraction

Cannot remove emulsified water. Gear pumps used in centrifuging increase emulsification. ;

Easy & total removal of free & emulsified water / moisture.

Cannot remove low molecular weight oxidised oil fraction

Removes

Cannot remove dissolved gases like Ammonia / Nitrogen.

Removes

Cannot remove solid impurities below 10 micron, efficiently.

In conjunction with Electrostatic-oil Cleaners, removal efficiency is better than 0.01 micron.

Centrifugal systems do not clean any dissolved gas

Clears the dissolved gasses very easily

Many high speed moving parts requiring frequent maintenance

Only two pumps. Vacuum & discharge & slow moving parts.

 

Automatic water discharge.

Low Vacuum Dehydration Machine

The extracted low-weight molecular oil gets accumulated in the hydraulic fluid and settles in oil. Hence (LVDH) low vacuum dehydration technique is used to clear the oil & ultimately bring back oil to its original properties.

This technology mainly evolves around the basic fact that the water boiling point is 100℃, and the vapor pressure above the water surface is atmospheric pressure but when we reduce the vapor pressure to a vacuum condition up to 750 torrs, then the boiling point of water gets reduced from 100℃ to less than 55℃.

Low vacuum dehydration machines are used to :

• Extracts water from oil
• Removes moisture from oil

Degrees of Cleanliness

 

Adopting a Vacuum Dehydration Process

 

1.

100%

Free and emulsified water alongside free gases

2.

95%

of dissolved  Water

3.

90%

of dissolved  gases

Hence under this technique, there is a vacuumed chamber and a shower arrangement for the oil (mixed with moisture content). There is a heater arrangement that heats up the oil under controlled temperature settings of a maximum of 55℃ only when the heated oil is showered inside the vacuum chamber under a high vacuum, moisture particles would get evaporated or get vaporized under the vacuumed condition thereby clearing the moisture from oil. Hence Clean oil is collected at the bottom of the chamber and delivered into the system.
