Supply and demand for natural gas have increased significantly over the last decade due to the implementation of innovative fracking technologies see Fig 1 LSU Center of energy studies 2019 and the recognition that natural gas is more environmentally friendly when compared to other fossil fuels such as coal and crude gas can be used for power
Coal preparation is defined as the process of removing the undesirable elements from run of mine ROM coal by employing separation processes to achieve a relatively pure uniform product These separation processes are based on the differences between the physical and surface properties of the coal and the impurities
To mine the coal coal getting itself it is necessary to have coal cleaning activity The purpose of the activity of cleaning coal is to remove impurities in the form of minor waste material soil from the surface of coal coal face as well as other impurities that were the result of precipitation agents surface water rainwater avalanches
The combination gravity and flotation methods demonstrate the technical feasibility of processing fine size coal to effectively remove sulfur and ash to recover high quality clean coal products which meet or exceed specifications for commercial grade coal as regards to Btu value and ash and sulfur content
Impurities Trapped Inside Coal Traces of impurities such as sulfur and nitrogen are trapped inside coal These impurities are released into the atmosphere when the coal is burned Combined with water vapor these impurities form droplets that fall back to Earth as a weak form of sulfuric and nitric acids commonly known as acid rain

A breaker boy was a coal mining worker in the United States and United Kingdom whose job was to separate impurities from coal by hand in a coal breaker Although breaker boys were primarily children elderly coal miners who could no longer work in the mines because of age disease or accident were also sometimes employed as breaker use of breaker
Ethanol helps to remove impurities and salts allowing DNA to clump together and be easily separated from the rest of the sample It also helps to preserve the integrity of the DNA during the
For many operations run of mine coal consists of a composite mixture of carboniferous material and various non coal impurities such as rock shale clay and water Coal preparation also denoted washing cleaning processing or beneficiation is the stage where invaluable impurities are physically separated from the coal material in order to
Coal preparation is the removal of undesirable material from the run of mine ROM coal by employing separation processes which are able to differentiate between the physical and surface properties of coal and the impurities Through proper coal preparation a uniform product is achieved Typical steps in coal preparation include Crushing
Syngas cleanup is a broadarea for eliminating the impurities associated with syngas obtained from gasification [10 11 12] A variety of criteria influence the selection of a gas cleaning system including the target emission level cost available space temperature gas composition and feedstock cleaning requirements for downstream applications
Coal washing is a type of clean coal technology used to remove impurities from coal before it is burned Washed coal is coal that has been mechanically washed off impurities such as ash soil rocks etc while unwashed coal is coal which has not been treated to
