Clicks: 18. On March 1, the Fertilizer Production Department held a mobilization meeting to launch the operation of the hydrogen supply unit. On March 8, comprehensive maintenance work on the hydrogen supply unit was carried out. On March 11, a gasification furnace began to undergo internal maintenance. On March 18, nitrogen and oxygen for external supply were provided following the completion of repairs to eliminate potential hazards in the new air separation unit. On April 2, all maintenance tasks related to hydrogen supply at Unit 1 were completed; the gasifier was ignited, and the hydrogen supply system at Unit 1 entered its operational phase. On April 8, Boiler No. 3 was started up, and 38 kilograms of steam were supplied externally that same night. On April 11, the hydrogen production facility completed all processes and produced qualified hydrogen. On April 11, the hydrogen supply unit in the fertilizer production department of Urumqi Petrochemical Company produced qualified hydrogen, and the valve was opened to supply hydrogen to the refinery, resulting in a successful first start-up of the unit. The fertilizer production department has completed its maintenance work and resumed hydrogen supply, which will address the company’s shortage of hydrogen needed for oil product upgrading, enhance crude oil processing capacity, and improve the product mix ； The excess hydrogen can also be directly supplied to the ammonia synthesis unit, increasing synthetic ammonia production and enhancing profitability. Integrated hydrogen supply is a significant measure taken by the company to improve quality and efficiency, as well as to reduce oil consumption and increase the use of alternative fuels. It reflects the company’s strong desire to accelerate its pace of high-quality development and to inject new vitality into fertilizer production. At the beginning of this year, the company issued an order to the fertilizer production department to restart the hydrogen supply unit No. 1, which had been shut down for two and a half years. To ensure a successful first start-up of the device, the Fertilizer Production Department promptly established a task force for hydrogen supply to resume operations, organized mobilization efforts, unified the thinking of all staff, and conducted a thorough analysis of the difficulties that would arise during the restart after maintenance. During the 40 days of maintenance work on the hydrogen supply system, it was necessary to carry out repairs on 815 items, including 2 natural gas compressors, 2 gasification units, all types of special equipment, as well as pipes and valves. In addition, tasks such as maintaining the burners in the boilers, ensuring the proper operation of the new air separation unit, carrying out 158 hours of work to eliminate potential hazards, repairing the second chemical processing unit and constructing interconnection lines, as well as providing training for staff, all had to be completed simultaneously. With limited time and high difficulties, despite numerous challenges, under the strong leadership of the company’s Party committee, thanks to scientific overall planning and reliable cadres and employees, the Fertilizer Production Department is determined to complete this arduous task. The Fertilizer Production Department carried out scientific planning, formulating detailed plans and measures, and set the overall goal of \"proper maintenance, operational readiness, stability, long operational life, and profitability.\" Coordinate in advance with the construction party, arrange the maintenance materials and personnel allocation, provide specialized training for the tasks involved, handle the related invoices, ensure safety management, etc. Detail the list of maintenance tasks, develop a maintenance plan, and carry out all necessary preparations before the maintenance work begins. Employees from various departments and workshops overcame the fatigue resulting from prolonged maintenance efforts and remained in a state of readiness at all times. Every step of the operations was carefully verified, and the various testing units were connected effectively, ensuring that all process steps proceeded smoothly and allowing for a successful first start-up as planned.
