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, marketers, finding 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 his 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.
