A Report on Clean Coal Technology in Today’s Society As the world we live in today continues to become more focused on “going green” and doing more to protect the environment, clean coal technology is one of the key focal points to look at. In 2003, each person in the United States consumed, on average, 3.7 tons of coal (Ristinen, and Kraushaar 19). This number has obviously increased year by year, and today it looms as a massive number. Coal usage has some well-documented detriments to the environment. Atmospheric problems, sulfur dioxide and acid rain, and global warming issues all can be directly linked to the heavy usage of coal burning. We Americans use massive amounts of coal each year, so naturally finding more clean and…show more content…
This allows for the coal which is burned up and used to provide energy to be filled with much less of the harmful toxins that affect people and the environment. One simple way that this can be done is by crushing the coal into tiny particles upon arrival at the power plant. After this, simply “washing” the goal will do the trick and remove many impurities from it. This method causes what is called the “pyritic sulfur” to be washed out. During the “washing” process, specks of iron are sent through the coal, bonding with this pyritic sulfur, which can then be easily disposed of (United States Department of Energy). Usually, during the actual washing process, larger chunks of coal are placed into a massive water tank. The coal will rise to the top of the water, whereas some of the other common impurities, namely sulfur, will sink to the bottom. Facilities around the country which clean coal in this manner are referred to as “coal preparation plants” (United States Department of Energy). While some methods, such as the two explained above, are effective in removing impurities like sulfur from the coal, some sulfur simply cannot be taken out. This is what we call “organic sulfur,” which actually is chemically combined with the carbon molecules in coal. This will prevent any aforementioned cleaning processes from taking out this sulfur. The only feasible way that this sulfur would be able to be removed is through a chemical reaction, but so far experiments with this type of
