    Crude Oils

    Process of making hydro-carbon base oils begins with Crude

    Oil

    Crude compositions vary

    Paraffinic

    Naphthenic

    Mixed Paraffinic and Naphthenic

    Selection of Crude depends on desired finished product

    Hydroprocessing - Refining Process

    Reaction of vacuum distilled crude oil and

    hydrogen at high temperatures

    (> 500 C) and pressure

    (> 70 bar) in presence of a catalyst

    Contaminants are eliminated andnaphthenics and aromatics are converted

    to paraffinics.

    Conversion of paraffins to iso-paraffins to

    improve low temperature characteristics

    Hydrofinishing is used to make moleculesize more uniform and remove remaining

    sulphur and aromatics

    Viscosity

    A measure of fluid's resistance to flow.

    Describes fluid resistance to shear force.

    Determined by molecular chain length

    A fluid with high viscosity resists motion

    because its molecular makeup gives it alot of internal friction.

    A fluid with low viscosity flows easilybecause its molecular makeup results invery little friction when it is in motion

    Measured in two ways Dynamic (Constant Pressure Head)

    Kinematic (Changing Pressure Head)

    Kinematic viscosity

    is measured based on the time required fora given amount of fluid to flow througha certified capillary while the pressure headis allowed to drop

    Units: Stokes (CGS Unit)

    1 cSt = 10-2 cm2/s = 10-6 m2/s = 1 mm2/s

    Units: Saybold Universal Seconds (SUS) Time in seconds for 60 milliliters of oil to flow

    through a standard orifice at a given temperature.(ASTM Designation D88-56.)

    viscosity) is measured based on the time required for

    a given amount of fluid to flow through acertified orifice under a constant pressure head

    can also be measured by a shear diskviscometer (e.g. Brookfield Rotating Disk Viscometer)

    Units: Pas (MKS Unit)1 mPas = 10-3 Pas = 10-3 kg/ms = 1 g/ms = 10-2 P(Poise)

    Relationship to Kinematic Viscosity

    Pour Point

    The Pour Point- the lowest

    temperature an oil or distillate fuel isobserved to flow, when cooled underconditions prescribed by test methodASTM D 97.

    The Pour Point is 3C (5F) above thetemperature at which the oil in a testvessel shows no movement when thecontainer is held horizontally for fiveseconds.

    In other words, the lowest temperaturea fluid pours from a container

    Benefits of Synthetic Gear Oils

    Improved efficiency (reduced energy

    consumption) due to reduced friction losses

    Oil change intervals three to five times longer

    than mineral oils operating at the same

    temperature Reduced Cost for machine down-times

    Reduced Cost for disposal of used oil

    Reduced operating temperatures under full load

    Increased component life

    Cooling systems may not be required
