A coalbed gas and natural gas comprehensive utilization park in Shanxi`s Shouyang county recently went into operation. It`s the first of its kind in China. The park will use 1 billion cubic meters of gas annually, producing more than 2 billion yuan in comprehensive output value and 500 million yuan in taxes. It will also become Shanxi`s first fuel gas-steam combined-cycle power plant and the biggest natural gas peak load regulation center in the province.
The park covers an area of 26.7 hectares and involves a total investment of 3 billion yuan. It consists of combined heat and power generation, low-concentration coalbed methane purification and liquidation, and coalbed methane comprehensive development and utilization. The project uses coalbed gas as fuel. Its gas turbine features a low-nitrogen combustion system, which can reduce 2.5 million tons of carbon dioxide per year, as compared with a coal-fired power plant. There will be no sulfide emissions and the nitric oxide emissions will be one-fourth that of a coal-fired power plant. The park uses residual heat to supply heat to Shouyang and can replace 10 five-ton-per-hour coal-fired steam boilers.
Officials said that the park can generate 723 million kilowatt-hours of electricity, supply heat for an area of 800,000 square meters, send out 130,000 tons of liquefied coalbed methane, and offer liquid (gas) service to 360,000 vehicles, replacing 10 million tons of fire coal and reducing 500 cubic meters of coal mine gas emissions. The park is committed to solving dust and gas pollution and plays an important role in ensuring stable energy supply, optimizing energy structure, safeguarding energy security and boosting the local economy in Shanxi.
About CHINA MINING
Since first held in 1999, the scope and influence of CHINA MINING has grown rapidly year by year. As a global mining summit forum and exhibition, CHINA MINING Congress and Expo has become one of the world’s top mining events, and one of the world’s largest mining exploration, development and trading platforms, covering all aspects of the whole mining industry chain, including geological survey, exploration and development, mining rights trading, mining investment and financing, smelting and processing, mining techniques and equipment, mining services, etc. playing an active promotion role in creating exchange opportunities and enhancing mutual cooperation between domestic and foreign mining enterprises.
CHINA MINING Congress and Expo 2014 will be held at Meijiang Convention and Exhibition Center in Tianjin on November 20th-23rd, 2014. We invite you to join the event and to celebrate the 16th anniversary of CHINA MINING with us. For more information about CHINA MINING 2014, please visit: www.chinaminingtj.org.
