DESULPHURISATION OF KEROSENE

ABSTRACT

This report aimed at determining  the presence and removal of mercaptan sulphur in kerosene using colour indicator method.  It is known that impurities such as free  sulphur,  sulphur dioxide, mercapters, funing materials etc. are found in petroleum products. Consequently,absorbents like molecular sieve, calcium oxide and even  activated carbon could  be  used  to trap these impurities, thereby making the  product impurity free.The afficac of  the absorption  using  calcium (Cao)  Ercammerer flask   was determined  by titration. Excess  Silver  Nitrate  is added to the sample ie effluent silves mercaptdes with he mercaptan sulphur compound present.  The excess silver  Nitrate is determined by titration with ammonium  thiocrante using ferric ammonium sulphate indicator .  Illustration  graphically shows that the percentage of sulphur in the sample reduces with increase in time.  Furthermore, it was noted that slight increase in quantity of kerosene fields better result.   TABLE OF CONTENT Cover page Title page Approval page Letter of Transmittal Dedication Acknowledgement  Abstract
