STEPS IN OIL MANUFACTURING PROCESS

ANALYSIS OF RAW MATERIAL

VISCOSIMETER

The time taken by a pre-determined quantity of oil to travel through a glass capillary tube of known dimensions, which is immersed in a bath kept at a constant temperature of 100° C, is measured and used to determine its viscosity.

TITRATION

When an oil is mixed with a reactant that changes colour in relation to pH levels, the former will resist colour changes by a degree determined by its composition. By measuring how long this oil takes to change colour, one can determine the concentration of its additives.
