Successful primary power supply for the dual-circuit incoming lines at the 10kV main substation of Hubei Shuanghuan Alkali Modification Project

Thread Content

Recently, the primary power supply for the dual-circuit incoming lines at the 10kV main substation of Hubei Shuanghuan Alkali Modification Project was successfully established. This has laid a solid foundation for subsequent tasks such as power supply and consumption in various equipment substations, individual testing of motors, and the commissioning of the plant’s control system. It also creates favorable conditions for the complete completion of the project. This project represents a concrete effort by China’s chemical industry to contribute to the achievement of the \"dual carbon\" goals and to the sustainable development of the energy sector. Once completed, it will have an annual production capacity of 600,000 tons of soda ash. Through technological upgrades and green transformation, it is expected that carbon emissions will be reduced by over 80,000 tons per year, while the overall energy consumption for producing soda ash will decrease by 28% compared to the current level. The Duhuan Company’s project for the renovation of its caustic soda production facility involves an investment of 1.365 billion yuan. The EPC contract was signed in October 2023, and construction work began on site at the beginning of November; completion is expected by the end of April 2025. The project mainly involves the construction of a new caustic soda plant with an annual production capacity of 600,000 tons, comprising processes such as carbonization, filtration, distillation and absorption, light ash treatment, crystallization, mother liquor exchange, dry ammonium production, packaging, and auxiliary services.
