Water ingression is either insidious as a result of atmospheric humidity levels or immediate as in water jet washing or sudden seal failure. Whatever the source, immediate attention is required to remove it.
If significant water ingress has occurred over a prolonged period, detailed oil analysis, such as rust and corrosion inhibition characteristics, remaining useful life measurements, demulsibility and foam suppression and tendency may also be necessary to determine the oil’s suitability for further use.
Merely replacing the oil will not cure the ingress source. Root cause corrective measures are necessary to resolve or limit water ingression.
Basic measures to address water ingression include the use of desiccating breathers, improved seal technology and training maintenance and operations personnel to avoid direct contact with wash down water on shaft seals and breathers.
Measures to minimize water ingress should start in the oil store. Drums and tanks should be sheltered from the environment.
Even indoors, this means they should be sheltered against process water sprays, fire sprinkler tests and general cleaning sprays. Open barrels should also be protected with desiccant-style filters, particularly in humid storage areas, to prevent water build up and oil degradation.
A number of methods or technologies, from inexpensive gravity separation to complex vacuum dehydration, exist to remove water.
Which technology is most effective will depend on the target dryness level required, the volume of water that must be removed, the base oil (mineral, synthetic, etc.) and the required flow and processing rate.
The following is an outline of technologies that can remove water from oil, together with their relative advantages and disadvantages.
