Yongqing Environmental Protection, as a leading enterprise in the environmental protection industry in Hunan Province, has undertaken more than 60% of SO2 emission reduction tasks in Hunan Province. The company has a number of qualifications such as Grade A environmental engineering design, Grade B electric new energy power generation, Grade B thermal power generation design, Grade A environmental pollution control facility operation, Grade III environmental engineering professional contracting, Grade B environmental impact assessment and so on, and has comprehensive qualifications related to flue gas desulfurization and denitrification business, environmental thermal power business, environmental engineering consulting business and environmental impact assessment business of construction projects. By the end of February 65438+2009, Yongqing Environmental Protection had completed a number of environmental protection projects in six high energy-consuming industries: steel, nonferrous metals, electric power, petroleum, chemicals and building materials. Yongqing Environmental Protection has become one of the few enterprises in China that owns the flue gas desulfurization project of steel sintering machine, and it is also one of the earliest professional companies in China that owns the operation performance of desulfurization equipment in large steel mills.

In 2008, the company was recognized as a national high-tech enterprise and has a provincial environmental protection technology center composed of high-quality technicians. Over the years, Yongqing Environmental Protection has paid attention to independent innovation, continuously increased the research and development of energy-saving and emission-reduction technologies, and successively carried out business cooperation and technical exchanges on energy-saving and emission-reduction with first-class universities and environmental protection enterprises such as George Institute of Technology in the United States, Edrico Company in Italy and Bakdur Company in Germany. Breakthrough progress has been made in limestone-gypsum wet flue gas desulfurization technology, circulating fluidized bed dry desulfurization technology, iron and steel sintering machine desulfurization, non-ferrous smelting furnace flue gas desulfurization, paper mill boiler flue gas desulfurization, flue gas denitrification, waste heat power generation, etc. A number of key technologies have been independently innovated, and scientific and technological achievements have been successfully transformed, making it one of the few enterprises with independent intellectual property rights of flue gas denitrification technology in China. The technological achievements of energy conservation and emission reduction developed by Yongqing Environmental Protection have been widely used in thermal power, steel, smelting, chemical industry, building materials, paper making, offshore oil and other industries.
