Coal waste fuel may reduce anthropogenic emissions – Study

Post  bejoy on Tue Jul 25, 2017 2:14 am

Scientists from Tomsk Polytechnic University (TPU) are developing a technology for fuel production from coal processing wastes. This fuel is ten times more environmentally friendly that will make it possible to resolve two problems at once: to reduce the amount of anthropogenic emissions of TPSs and efficiently dispose wastes from coal processing and beneficiation. The research team of the Department of Automation of Thermal Power Processes led by professor Pavel Strizhak shared its outcomes.
As Strizhak noted, thermal power plants generate up to 40-45 percent of the world’s electricity. Meantime, TPSs are the sources of five contaminants which account to 90-95 percent of all emissions to the atmosphere such as cinder particles, sulphur oxides, nitrogen and carbon oxides as well as water vapour. Operating TPSs release carbon dioxide (CO2) which scientists consider as the main cause of the green gas effect. Besides, particles of volatile cinder released into the atmosphere may contain other compounds, in particular, heavy metals. Gaseous products of organic fuel combustion may also include toxic and carcinogenic microelements, carcinogenic hydrocarbons and other harmful substances.
“The increase of concentration of nitrogen oxides contributes to the destruction of the ozone layer which protects our planet from ultraviolet space radiation,” said Strizhak.
To reduce the impact of anthropogenic factor on the environment and the amount of pollutants emitted into the atmosphere, TPU scientists suggested the production of carbon water slurry containing petrochemical (CWSP) fuel compositions out of wastes remained after coal beneficiation or oil refinery.
