Saturated crystallization in the absorber technology was successful developed
By-product ammonium sulfate of the Chongqin Zhongliangshan project: the nitrogen content in the product reached 20.8% which met the standard of GB535-1995. This indicated that it was a breakthrough for JNEP (China) to realize the crystallization inside the FGD absorber.
National Grade A Design Qualification was obtained
Jiangnan Environmental Design Institute was established: JNEP (China) decided to depend on its own to design desulfurization project. In August of the same year, it obtained the Grade A Design Qualification in Environmental Protection Projects (air pollution prevention and control project) and embarked on the road of independent design.
Ammonia-based FGD technology recognized and recommended by the Country
"Ammonia desulfurization technology on-site review conference" was held: the on-site review conference of Jiangnan ammonia desulfurization technology was held in Nanning, Guangxi which was organized by China Electricity Council. Environmental Resource Department of National Development and Reform Commission (NDRC), Science and Technology Department of Ministry of Environmental Protection, other competent departments and five major power groups attended this conference. The expert panel composed of 9 experts considered that ammonia desulfurization technology is a green desulfurization technology which can truly achieve circular economy. The technology is especially suitable for the new construction and renovation project of flue gas desulfurization of power plant boilers and process furnaces with high sulfur content in coal.
National Awards was obtained
Awarded by the Ministry of Science and Technology of China: the independent intellectual property right "Development and application of resource recovery wet ammonia-based desulfurization technology" which completed by JNEP (China) won the second prize of national environmental protection science and technology award.
Developed national standard for ammonia desulfurization
Implementation of national standard for ammonia desulfurization: this standard named is prepared by JNEP (China) entrusted by the national environmental protection department. Since then, the clear technical specification for ammonia flue gas desulfurization project of thermal power plant in China had been established.
The company changed to a stock company
Completion of JNEP (China)'s restructuring: JNEP (China)'s founding meeting and first general meeting of shareholders were held. The overall restructuring was changed into a joint stock limited company with a registered capital of 80 million RMB. The company was renamed as Jiangsu New Century Jiangnan Environmental Protection Co. Ltd. The listing was launched in an all-round way.
