Alternatives technologies to Gas flaring Dissertation

Alternatives technologies to Gas flaring - Dissertation Example The gas is emerged due to the drilling of oil and then separated from oil; it is released by pressure relief valves through vertical pipes. Gas flared through combustion affects the green house gases up to a considerable extent. The flaring and venting of gas from oil drills plays a very important role in emissions of greenhouse gas. The emission of greenhouse gas was at peak during 1970s around 110 million metric tons per year but it has been declined since then by more than three quarters and now estimated around 0.5% of all carbon dioxide emissions. As per the Kyoto Protocol, a carbon bonus had been announced for garbage collecting companies in some developing nations for installing combustion devices for the methane gas. These devices will help in preventing methane to reach the atmosphere by burning it. The burning effect converts the methane into water, carbon dioxide (CO2) and heat. As methane is twenty three times more powerful than carbon dioxide, it will also help in reduci ng greenhouse gas emissions with the same proportion. The gas flared and vented during the drilling process is very worth while and can be used for various purposes. According to a report by World Bank, "Over 150 billion cubic meters of natural gas are flared or vented annually, an amount worth approximately 30.6 billion dollars, equivalent to 25 percent of the United States’ gas consumption or 30 percent of the European Union’s gas consumption per year." The flaring and venting is condensed within some countries. According to the Wikipedia, "10 countries account for 75% of emissions, and twenty for 90%. The largest flaring operations occur in the Niger Delta region of Nigeria. The leading contributors to gas flaring are (in declining order): Nigeria, Russia, Iran, Algeria, Mexico, Venezuela, Indonesia, and the United States.[6] In spite of a ruling by the Federal High Court of Nigeria (that forbade flaring) in 2005, 43% of the gas retrieval was still being flared in 2 006. It will be prohibited by law as of 2008." Research Topic: The effects of gas flaring on the environment and to find alternative techniques to reduce its impact on green house gas emissions. Research Objectives / Purpose of study: The research objectives include some overall objectives that will be generalized and also some specific quantitative objectives as discussed under: To identify the risks associated with excessive gas flaring; To identify factors that influence the high and accelerated rate of greenhouse gas emission; To explore past trends of gas flaring; To identify strategies that have been implemented around the world to reduce gas flaring effect; To research and evaluate the possible alternate technologies that can be used to reduce the effect of gas flaring on the environment; & To identify the finest and environment-friendly technology for the purpose of gas flaring. Expected Outcome: The expected outcome of this research work is to achieve all the research objec tives stated above by testing the authentic and established approaches used previously for reducing emission of gas flaring and venting. Literature Review: According to the Fuel for thought: an environmental strategy for the energy sector (a report from the Environment Department of World Bank, 2000), there are many reasons of gas flaring and venting. The most significant one is the lack of resources to utilize the gas emitted
