Jiangsu Zhongneng Silicon Technology Development Co., Ltd. Technological upgrading project - 100,000 tons cold-hydrogenation project was officially put into operation recently. According to reports, this is the largest cold hydrogenation unit in the world.
It is reported that the cold-hydrogenation process is one of the most important nodes in the polysilicon production process, and is also the decisive link for the Zhongneng Silicon Industry in Xuzhou to achieve “cost reduction and efficiency increaseâ€. The 100,000-ton cold-hydrogenation project summarizes the operating experience on the basis of a 50,000-ton cold-hydrogenation process and improves the optimization of foreign technologies, which can substantially increase the output and simultaneously completely react the toxic by-product silicon tetrachloride in polysilicon production. It is trichlorosilane.
Gate Valves are called "full-flow" valves; there's a direct unobstructed path for flow right through the middle of the valve. A wedge-shaped brass gate is lowered into a machined slot to close the valve. They should either be completely open or completely closed. Water flowing through a partially open gate valve wears away the metal and causes the valve to fail over time.
