Abstract

Data on pollutant emissions in Nigeria were collected across the states to detect any significant change which may cause harm to human health and the environment at large. Three theoretical distributions; Weibull, Log-normal and Gamma distributions were examined on the gas flaring (carbon monoxide) observations to determine the best distribution for the pollutant emissions. The characteristics of the pollutant emissions were obtained and the probabilities of exceeding the Federal Environmental Protection Agency (FEPA) acceptable limits were estimated.

Highlights

  • Gas flaring may be defined as the burning and releasing of natural gasses which are associated with crude oil when they are released from the ground

  • Three theoretical distributions; Weibull, Log-normal and Gamma distributions were examined on the gas flaring observations to determine the best distribution for the pollutant emissions

  • In the present research work, the probability distribution of carbon monoxide flaring across the 36 states of Nigeria for the period of twenty-one (21) years is investigated and the probability that the carbon monoxide emissions would exceed the acceptable limit of its concentration in Nigeria is estimated

Summary

Introduction

Gas flaring may be defined as the burning and releasing of natural gasses which are associated with crude oil when they are released from the ground. No doubt, flaring and venting of associated gases contribute significantly to greenhouse gas (GHG) emissions and has negative impacts on the environment (World bank, 2001), The environmental problems caused by flaring, are global, but to some extent, regional and local. Real historical data were used on the subject phenomenon to develop the analytical form of the equations This model was used to predict 10 - 50 year rate of change of the entities that constitute CO2 emissions which may be useful for strategic planning and formulation of policies to mitigate global warming. In the present research work, the probability distribution of carbon monoxide flaring across the 36 states of Nigeria for the period of twenty-one (21) years is investigated and the probability that the carbon monoxide emissions would exceed the acceptable limit of its concentration in Nigeria is estimated
