The method is internationally recognized as the best process as it is able to separate the total content oil material from its residue. Hence, the base oil derived is known to be of better quality than that directly derived from petroleum. The refinery process with this method is done in five stages.
Its purpose is to separate the water content in the used oil and to guarantee the smoothness of the refinery process, preventing from clog and rust.
This process is to separate unintentionally taken fuel such as diesel engine oil.
The device brought from Germany works in a high vacuum condition. This third stage yields distilled oil free from fuel and residue.
Its purpose is to resaturate the bond among the carbon atoms and to free it from sulphur and chlor content. This process produced clear base oil which is very stable against oxidation reaction as to guarantee the maximum efficiency of the oil. This oil even has a better quality than base oil derived directly from crude oil
All the refinery processes are automatically done controlled by computer and strictly monitored as to ensure that there is no single drop of oil fall to the ground which potentially pollutes the environment.
