! Shaanxi Coal Group invested 62 billion yuan in the construction of two substations as part of Phase 1 of the second phase of the Yulin Chemical project; these substations have now been completed. Recently, the synthesis gas purification unit’s substations for this project, which are under the general contracting of China National Chemical Engineering Corporation Donghua, were successfully completed, marking an important milestone in the civil construction work in this area and laying a solid foundation for the subsequent mechanical and electrical installation tasks. Recently, significant progress was made on the external piping project for the entire plant (Bid Section 1) of the Phase 1 of the second phase of Yulin Chemical Plant, operated by Shaanxi Coal Group – a project that is under the general contracting of China National Chemical Engineering Donghua Company. The main structure of the auxiliary power substation No. 1 was completed 35 days ahead of schedule, creating favorable conditions for subsequent electrical installation and commissioning work.
