• BioKem has the equipment and the know-how to
  perform on-site oil flushing and oil rejuvenation
  services. Are you having trouble achieving OEM
  Turbine or Compressor Start-up specifications?

• Routine Filtration and High Velocity / Hot
  Oil Flushing Services after shutdowns and before
  commissioning are an important part of preventive
  maintenance for all rotational equipment and
  systems.

• The damaging effects of particulate contamination
  have been well documented with regards to
  premature component wear and failure. One way to
  ensure optimal system cleanliness is to perform
  periodic flushing.

7

• By circulating hot oil or a flushing
  fluid through the piping of a system at a very
  high flow rate, turbulent flow can be achieved,
  which dislodges particles that would otherwise
  cling to the walls during laminar flow.

8

• The benchmark is a Reynolds number of 4000 or
  greater, essentially significantly greater than
  laminar flow for the oil.

• Whilst the removal of particulates is an obvious
  solution, the removal of moisture and maintenance
  of a moisture-free environment for your close
  tolerance machinery also adds significant life to
  that equipment.

• Moisture can resolve itself in lubricating
  systems creating unwanted side effects such as
  corrosion, varnishing, and impingement.
  Corrosion is self-explanatory and need not be
  addressed here, whereas the creation of varnish
  is an entire subject on its own.

11

• In general, varnishing of internal components of
  a lubrication system can decrease tolerance
  clearance, cause valves to stick, and ultimately
  gum up lube channels and pathways with a
  significantly detrimental effect. The effect of
  varnishing is estimated to cost industry billions
  in lost time and maintenance.

12

• Moisture can also be destructive in other ways,
  causing micro-impingement as it is compressed by
  the surrounding oil and responds by momentarily
  turning to super-heated steam. This steam has
  the effect of etching the surfaces of the very
  surface it should be protecting.

13

• Either way the presence of moisture in lube oils
  is not wanted.
• BioKem oil Services has a range of service and
  static solutions to remove moisture and
  particulate matter from oil. Vacuum dehydration
  is very effective as warms the oil, and increases
  the surface area of the oil under a vacuum to
  flash off the unwanted moisture.

• The process will also remove unwanted entrained
  and dissolved gasses. Through this process the
  oil is not stressed and retains the valuable as
  extreme pressure (EP) and extreme wear (EW)
  additives.
