The DMC unit of the Jingmen Yuanhan electrolyte precursor project carried out by China National Chemical Engineering Donghua Corporation was successfully completed. On the afternoon of December 9, another good news came regarding this project: the DMC unit was finished, marking the official transition from the construction and installation phase to the commissioning phase. Construction on this facility began on December 9, 2024, and it was completed on December 9, 2025, taking one year in total. As the general contractor for the project, Donghua Company coordinated all the parties involved, and through daily meetings, ongoing monitoring, and task tracking, it made every effort to complete the remaining construction tasks and carry out debugging work. This ensured that key stages such as individual unit tests of the equipment and electrical and instrumentation debugging were all completed to the required standards, thereby laying a solid foundation for CCCC. Next, the project team will continue to work together efficiently, making every effort to ensure that the subsequent joint commissioning and startup are successful on the first attempt. On December 4, the EPC project for sulfuric acid production using sulfur at Indopura in Indonesia, which was overseen by China National Chemical Engineering Donghua Corporation, successfully produced qualified deionized water. This achievement created favorable conditions for subsequent tasks such as system cleaning, joint commissioning, and the heating and baking of the main equipment. Since the construction began in August 2024, the project team has organized tasks scientifically and advanced them steadily. At present, instrument air, process water, desalinated water, and regular electricity are in use; materials such as alkali solutions, hydrochloric acid, and sulfur have been delivered. All tasks related to commissioning, testing, and implementing the \"three inspections and four fixations\" procedures have been fully underway. Next, the project team will, as always, remain true to its original intentions, organize and plan meticulously, coordinate resources efficiently, and ensure that the commissioning process is completed with high quality.
