1) Jiangsu Zhongneng currently operates 4 production lines with a capacity of 10,000 tons each; by the end of 2011 its production capacity reached 45,000 tons, and by mid-2012 it reached 65,000 tons； 2) Luoyang Zhongsi currently has a production capacity of 5,000 tons; a new production line with a capacity of 10,000 tons is under rapid construction, and there are further plans to increase capacity to 50,000 tons ； 3) Shuanan Environment is currently constructing 5,000 tons ； 4) Inner Mongolia Fengwei Phase I: 3,000–5,000 tons ； 5) LeDian TianWei to expand production by 3,000 tons ； 6) Sevi LDK’s new phase with a production capacity of 10,000 tons 7) Sichuan Ruineng currently has a production capacity of 5,000 tons ； 8) Hengdian Dongci Phase I: 5,000 tons ； 9) TBEA Phase 1: 5,000 tons ； 10) Linzhou Zhongsheng Phase I: 3,000 tons ； 11) Yunnan Mingyong Phase I: 3,000 tons ； 12) Phase 1 of Zhongzhou Silicon Industry: 3,000 tons ； 13) Wannian Silicon Industry Phase II: 3,000–5,000 tons ； 14) Daquan New Energy to expand capacity by 3,000 tons ； (Thermal hydrogenation method) 15) Liujiu Silicon Industry: 3,000 tons (silane method) ； 16) Zhongning Silicon Industry (silane method); 17) Yinxing Energy, Xuntianyu, and Jingxin (physical metallurgy method). According to relevant data, the additional production capacity added between 2011 and 2012 totaled approximately 180,000 tons. Of this amount, while Liujiu Silicon Industry used the silane method, Daquan New Energy employed the thermal hydrogenation method, and Yinxing Energy, Xuntianyu, and Jingxin used physical metallurgy methods, cold hydrogenation technology was responsible for around 173,000 tons of the increased production capacity.
