On February, 2024, the carbon disulfide and dimethyl sulfoxide workshops of Xinfajinguan Company began a 27-day annual overhaul, including shutdown, replacement, purging, and steaming of the equipment. This overhaul encompasses 118 projects in total, with 76 for the carbon disulfide workshop and 42 for the dimethyl sulfoxide workshop. According to company plans, 22 hidden hazards requiring shutdown will also be addressed to ensure the optimal operation of the equipment.

Overhaul Schedule

The total duration of the annual overhaul is 27 days. However, 3 days are required for shutdown, replacement, cooling, and purging of the equipment. Additionally, the overhaul coincides with the annual Spring Festival, during which special operations cannot be performed, and the company allows an 8-day holiday for all staff. Thus, the actual effective overhaul time is only 16 days. During this period, 118 overhaul projects and 22 hidden hazard rectifications need to be completed, making it a tight and challenging schedule.

Implementation Details

Currently, the annual overhaul is nearing completion. Most overhaul projects have been finalized, and hidden hazard rectifications have been implemented one by one. To further ensure the quality of the overhaul, the company's chairman personally led a team of professionals from equipment, process, workshop, and safety departments to inspect and confirm each completed project on-site. The meticulous overhaul attitude and responsible work ethic have laid a solid foundation for Xinfajin to achieve its 2024 safety and environmental production goals.
