XPTC has researched and developed 6 series and 40 types of special chemical agents for power plants. N-307 Complex Corrosion and Scale Inhibitor were awarded the second-class prize by Northwest Bureau of Power Administration. XPTC owns chemicals production line with capacity more than 10000 tons per year. The products are supplied not only to domestic power plants in more than 20 provinces but also exported to Southeast Asian countries.

Products	Application	Characteristics	Efforts

In the middle of the fifties, the first batch power plant workers has met in Xi’an, developed the famous phosphoric series water treatment chemicals and boiler acid cleaning inhibitor and made a contribution towards the development of our county’s electric industry. As to accelerate the technology industrialization, our institute altered the system and set up the Xi’an Xieli Power Technology Co., Ltd.-a high and new technology company. Combining with different agent condition and depending on advanced equipments and instruments, we developed 6 series products, 40 types’ power plant chemicals and set up a manufacturing line of 10 thousand tons one year. The products are supplied not only to domestic power plants but also exported to Middle East and the north of Europe.
