Natural Gas: environmental effetcs.


As we have previously indicated in the last blog, there are important advantages that make natural gas a better option among the fossil fuels currently used. The most important one is the way it affects the environment. Nowadays, natural gas is considered by many people as the less harmful and most friendly of the hydrocarbon resources. In the lines beneath, this text will cover some of those environmental issues related to the use of natural gas.
Among all the fossil fuels, natural gas is the cleanest one. In almost every combustion process, such as the one that takes place while burning gas, carbon dioxide (CO2), water vapor, sulfur dioxide (H2S), and nitrogen oxides (Nox) are the primary products release to the into the environment. However, the amounts of each one of these products is far smaller than the amounts released by the combustion of heavier fossils like coal and fuel oil. The reason is linked to the fact that natural gas is mainly composed of methane (CH4), whose molecules contain lighter chain of carbons. Additionally, contrary to other hydrocarbons, natural gas does not release considerable quantities of ash particles which are another important pollutant usually invisible or imperceptible to the human eye.
Green house emissions, smog, air quality, industrial and electric generation emissions, and pollution form the transportation vehicles are some of the problems our society is facing right now. As human population continues to grow, we begun to use more and more resources and fossil fuels are our fist choice. A simple example is represented by the use of cars and other common methods of transportation, but cars or any other transportation vehicle are a necessity. Thus, the emissions released into the atmosphere keep increasing with the time. The rate of emissions stands side by side the consumption of fuels. Natural gas, even though does not eliminate the problem, it minimize the effect. For example, vehicles operating with compressed gas have reductions in carbon monoxide (CO2) emissions of 25% in comparison to those emitted by traditional gasoline or diesel cars.

Wow, this is all really great information. You are certainly becoming an expert about natural gas. I wonder if you are going to study to become a petrochemical engineer . . . you'd be awesome!

W-O-W thats just too much edward =P

Relax, way too much info and too formal for a blog, they should be fun ;)

Enjoy ur holiday xP

Ohh, I should have used this info for my essay :))
