Recently, the construction of Yongxiang Energy Technology’s 120,000-ton high-purity crystalline silicon project is progressing in an orderly manner. Currently, it is nearly one and a half months ahead of schedule. Three of the five core devices have completed civil construction, delivery and installation. The project is expected to enter trial production status in June. The total investment of the 120,000-ton high-purity crystalline silicon project is about 6.5 billion yuan, covering an area of about 1,000 acres. After reaching capacity, Yongxiang’s annual output of high-purity crystalline silicon will exceed 200,000 tons. The project integrates nearly 20 years of R&D results of Yongxiang Co., Ltd. in the field of polysilicon. The production equipment and process system will reach international leading levels in terms of safety, environmental protection excellence, advanced indicators, as well as automation and intelligence.
Sichuan Yongxiang Energy Technology Co., Ltd. is a large-scale private technology enterprise owned by Sichuan Yongxiang Co., Ltd., a subsidiary of Tongwei Co., Ltd. It is mainly engaged in the research, development, production and sales of professional high-purity crystalline silicon (polycrystalline silicon, monocrystalline silicon, electronic grade polycrystalline silicon). The company was established in July 2021 and is located in the New Industrial Park in Wutongqiao District, Leshan City, Sichuan Province. Yongxiang Co., Ltd. has an internationally advanced technical talent team and R&D capabilities. It has established a polysilicon engineering technology research center, a corporate technology center, a high-purity crystalline silicon preparation engineering laboratory, and a postdoctoral innovation practice base. It has more than 300 achievements in independent intellectual property rights in technical fields such as cold hydrogenation, large-scale distillation energy saving, tail gas recovery, thermal energy cascade comprehensive utilization, and closed-circuit circulation of chlorine and hydrogen elements.
This plant has relatively good infrastructure and management and is a model plant in Sichuan's chemical industry. I visited the site in 2021 and was impressed by the standardization and 5S.
It would be good to build roads first and then build facilities.
