Development of a Mathematical Model for the Assessment of Hydrogen Sulphide Pollutant in Air

Abstract

This work is aimed at developing a mathematical model to determine the concentration of hydrogen sulphide pollutant in the air from a gas flare of a refinery. To achieve this, experimental data on concentration of hydrogen sulphide from Kaduna refinery and petrochemical company, Nigeria were collected, and the dispersion model was developed based on Gaussian distribution principle. The simulation of the model was carried out using visual basic programming. It was observed from the simulated results that the gas dispersion model developed for hydrogen sulphide showed a remarkable agreement with the dispersion pattern and agrees with the experimental results with a correlation co-efficient of 0.98. Thus, the model can be used to determine the safe distance for human habitation from an industrial area and the refinery in particular.
