18.04.2017 | Why Are CHP Closing All Over The World?
Burning of coal nowadays has become a big problem. The main reason for this is a rapid increase of mankind. So, China burns half of coal in the world. Since 2000 the share of coal in world energy production has increased from 25 to 30%, and the Chinese economy is responsible for 82% of this growth. In Beijing, it is customary to use individual heat sources such as electric heaters and the like. To produce huge amount of electricity, you need to burn enormous quantity of coal to local power plants, and this leads to the fact that "locked" between the mountains the city is choking in smog from the coal operation of CHP.
Given the stance of the society, the Chinese government is taking measures to reduce pollutants emissions from coal combustion. China is among the countries who refuse the use of coal in the framework of the Paris Convention, which is to "strengthen the global response to the threat of climate change by keeping a global temperature rise this century well below 2 degrees Celsius above pre-industrial levels and to pursue efforts to limit the temperature increase even further to 1.5 degrees Celsius".
The danger of using coal is not only the fact of burning, but also impurities which are released into the atmosphere together with stack gases. Mercury is one of the most toxic trace impurities in coals. In the process of coal combustion in thermal power plants the mercury goes into the environment. For effective control of emissions, it is necessary to have full information about the mercury content of the feedstock, flue gas, bottom ash and other liquid and solid wastes. Obtaining these data is a challenging analytical task, because the mercury content of coal and its combustion products can vary within wide limits.
The company "Lumex Instruments" offers a method for the direct mercury determination in coals in accordance with the standards (ASTM D6722-01 (2006) and EPA 7473), which implies thermal decomposition of the sample in combination with catalytic conversion, amalgamation and quantitative determination by AAS. Application notes can be found here.
Regular meetings of experts on the problem of mercury emissions from coal burning has been conducted since 2003 in Europe, North America, Asia, Australia and South Africa. The company "Lumex Instruments" takes part in those events since 2006. MEC workshops are organized with the aim to ensure direct interaction of international experts representing the energy sector, government bodies, research institutions and commercial companies to discuss the General problem of mercury emissions into the environment from coal combustion.
Specialists of the company "Lumex Instruments" actively participate in events, devoted to the problem of mercury emissions to environment:
- Mercury Workshops In South Africa
- "Lumex Instruments" At Analytica Vietnam 2017
- Live Webinar: Simple Mercury Analysis Of Complex Samples: Soil, Oil, Foodstuffs, And More
- Solutions For Monitoring Of Mercury Emissions Presented At CEM 2016
- "Lumex Instruments" took part in the MEC12 (Mercury Emission from Coal) workshop, organized by the CCC (Clean Coal Centre) of the International Energy Agency (IEA)
- The workshop was held in South Africa, in the Mpumalanga province, where most coal deposits and coal-fired power plants South Africa are located
