To meet the world energy requirement hydraulic fracturing plays very important role to increase the productivity of natural gas and oil. After acquiring greater success from a decade, Hydraulic fracturing has made robust roots from which maximum production can be taken from unconventional reservoirs which is not only a positive sign for industry but it is also offering attractive employment
To begin with, the advancements in agriculture, manufacturing, and transportation have caused a rapid increase in fossil fuel burning such as coal, oil, and natural gas, as well as other practices that release pollutants in the atmosphere since the Industrial Revolution in 1850 . These forcings have affected the temperature of the earth because concentrations of carbon dioxide, methane, and nitrous oxide have increased in the atmosphere , and carbon dioxide which is known to be a greenhouse gas  is a main component to the warming of the earth . These greenhouse gases trap some of the heat on earth by absorbing solar radiation and re-emitting heat in all directions  which essentially leads to the increase of temperature in the earth. It is also measured that greenhouse gases with a higher Global Warming Potential (GWP) absorb more energy per pound, which warms the earth even further . Moreover, the
Scientists discovered that carbon dioxide is an important effective gas for the greenhouse effect. Moreover, gases like carbon dioxide, methane and water vapour can affect the energy balance of the Earth. This happens because they are able to absorb the longwave radiations emitted from the Earth’s surface. The result of this process is the increasing of the amount of the heat energy in the Earth’s climatic system. With no greenhouse effect, the average of the global temperature of the Earth would change from 15 to -18 Celsius.
The higher rise (90%) of CO2 came from industry developed countries as Europe, North America and Asia. The main cause of high increasing of CO2 on the atmosphere is using and combustion of fossil fuels, automobile industry and deforesting. Without flora, Earth can not absorb carbon dioxide and it would create a layer that heats up Earth surface.

Global warming can be defined as the heating up of the earth’s atmosphere due to greenhouse gases causing the “greenhouse effect” in which gasses like carbon dioxide, nitrious oxide, methan get trapped in the earth’s atmosphere and raises its temperature. Global warming cause a chain of subsequent events disastrous to human life and the environment such as natural calamities, reduction in water reserves, extinction of wildlife, rise in the seal levels and many more. Scientists say that there are two main activities that cause global warming which can be categorized into human activities and industrial activities. Even though human activities up to some level are responsible for global warming it Is the industrial activities that aggravates it. Industries generate greenhouse gases during their production process.
One can infer from the reactions, 1 step is preferred over 2 step process as the hybrid catalyst used in one step process allows synergy between the reactions which results into higher syngas conversion per pass or greater productivity by consuming methanol as soon as it forms. The synergy between the reactions works in the following way : Methanol produced in reaction (1.1) get consumed in reaction (1.2) immediate after its formation, water produced in reaction (1.2) favours the product formation of reaction (1.3) according to Le Châtelier's principle and finally H2 produced in reaction (1.3) again used in reaction (1.1), therefore increasing its rate of
Since the industrial revolution, we have been relying on extracting and burning billion tons of fossil fuel which are oil, natural gas, and coal. These fossil resources generate gasses such as CO2 that lock up the heat and result in major changes in the climate. As a result, burning fossil fuel is a major cause of global warming, because it increases the concentration of CO2. The United Nation Environment Program states that the carbon dioxide emissions that human is producing from fossil fuel today equals “5.9 billion metric tonnes of carbon in 1992” which is three quarters of the total CO2 produced by human in general (http://unfccc.int, 2000). We use and burn fossil sources for many purposes such as generating power, transportation, burning and cutting trees, creating chlorofluorocarbon, and many other industries.
For example, in order to generate electricity, fossil fuels are burned. This result in the emission of the CO2 and according to the United States Environmental Protection Agency (EPA), the process of generating electricity is the largest source of emission of carbon dioxide producing 38% of
There are a number of factors that allow scientists to believe that human activity is the source of climate change. Carbon emissions are the main cause of global warming. When human beings burn carbon based fuel like coal and gasoline for energy, the carbon dioxide they release is lighter than the carbon dioxide from other sources. The level of lighter carbon dioxide has increased drastically in the last 40 years. Another cause of global warming is deforestation.
INTRODUCTION The purpose of my report is to discuss the possibilities of improving the oil refineries in order to maximize their efficiency of them and minimize the pollution caused by oil refineries around the world. It is known that oil production is now one of the biggest factors that control the world economy and that oil products have changed our life to be more advanced and civilized. However, these oil products have to pass through many processes in an oil refinery before we can use them in our daily life causing many negative effects on our planet. One example of these negative effects is global warming. The structure of oil refineries should be improved to decrease these impacts.
