DO YOU KNOW WHERE THE KEROSENE,GREASE AND OTHER MATERIALS OF THIS KIND ARE GOTTEN FROM

IT IS FROM THE REFINING OF CRUDE OIL

crude oil is a complex mixture of hydrocarbon that can be seperated into different fractions..The basic concept used in refining crude oil is known as DISTILLATION which involves the volatility of the constituent.The higher the volatility,the lower the boiling point..i.e the most volatile compound in the crude oil will be collected first when crude oil is explored.it is brought and kept in a tank  with its protecters which are ozone depleters.The refinig process can be achieved through the following four processes...

FRACTIONATION; MAINLY DISTILLATION
CONVERSION PROCESS; IT INVOLVES THERMAL,CATALYTIC CRACKING AND ALKYLATION.
TREATMENT;WHEN PRODUCT ARE TREATED TO MEET  THE MARKET SATNDARD E.G ANTI KNOCKING PROCESS AND BRANCHING..WHERE UNDESIRABLE COMPOUNDS SUCH AS SULPHUR ARE REMOVED BY STREAM STRIPPING..
SUBSIDIARY SANCTIONING; IT INVOLVES THE BLENDING OF ALL INGREDIENTS THAT ARE GOING TO BE USEFUL  IN THE PRODUCTION OF PETROLEUM TO IMPROVE PERFORMANCE AND LIFE STYLE..E.G BITUMEN CAN BE BLENDED WITH SOLVENT TO FORM A CATCH BACK GREASE..THIS IS DONE BY DISPERSING A THICKENING AGENT IN OIL..

THE TEMPERATURE
THE RATE OF HEAT
THE RATE OF COOLING
DURATION OF STIRRING ARE CONDITIONS THAT MUST BE NET AS TO THE  TYPE OF GREASE BEEN PRODUCED..

THE MORE THE STIRRING,THE LOWER THE VISCOSITY..

EXAMPLES OF THE FINISHED PRODUCT IN THE BRAKING DOWN OF CRUDE OIL ARE
NATURAL GAS MAINLY METHANE AND ETHANE
LIQUEIFIED PETROLEUM GAS
GASOLINE
WHITE SPIRIT
GAS OIL
DIESEL OIL
FUEL OIL
LUBRICATING OIL
KEROSENE
BASE OIL..
