Urumqi Petrochemical Fertilizer Plant produces qualified urea Author/Source: Economic Daily Date: 2019-08-13 Clicks: 13 On August 10, reporters learned from the Urumqi Petrochemical Branch of China National Petroleum Corporation (hereinafter referred to as “Urumqi Petrochemical Company”) that the second fertilizer production unit of this company has completed all processes and is now producing qualified urea products. Using natural gas as raw material, this facility is expected to have an urea production capacity of 520,000 tons. The second chemical production unit of the Fertilizer Plant at Urumqi Petrochemical Company consists of two production units for synthetic ammonia and urea. Using natural gas as raw material, and employing the Brown process for ammonia production and the Stamicarbon process for urea production, this facility has achieved 11 times the target production levels since it was put into operation in May 1997; it has also set multiple records for continuous operation of facilities of this type. In 2011, it was decided that Unit 2 would be used for intermittent production as a natural gas peak-shaving facility, and by 2016, Unit 2 went into a three-year shutdown. In 2019, driven by the need for high-quality development, the resumption of operations at Wushihua’s Second Chemical Plant became a key project for transforming hydrogen supply methods, reducing production costs, improving efficiency, and fostering sustainable development. To ensure the successful resumption of operations for this facility, Wushihua established a dedicated organizational body in June to oversee the resumption of work at the second chemical processing unit, breaking down departmental and workshop boundaries to facilitate its operation. Han Guangming, the chief engineer of the fertilizer plant at Urumqi Petrochemical Company, said, “The second chemical processing unit offers a wider range of adjustment possibilities and greater flexibility; it can be used to produce urea as well as to meet the demand for hydrogen production at lower levels of capacity. It is the best option for the company to optimize its production processes and improve its profitability.” ” To ensure the successful resumption of operations, the fertilizer plant overcame numerous challenges, including extensive maintenance work, heavy workload associated with starting up the equipment, complex site conditions, multiple concurrent tasks, and persistent high temperatures. At 19:20 on August 10, the second conversion unit completed all processes, producing qualified \"Kunlun\" brand urea products, thus achieving successful resumption of operations for this unit. Since 2019, the domestic urea market has seen a recovery. It is estimated that the cost of producing urea from natural gas is around 1,200 yuan per ton; if production resumes, a profit of at least 400 yuan per ton can be achieved. To ensure smooth production and distribution, the Marketing and Logistics Department of Urumqi Petrochemical Company has held discussions with relevant parties regarding product quality, packaging requirements, and shipping arrangements, thereby establishing the sales principles for urea products. At present, the fertilizer plant of Urumqi Petrochemical Company is closely monitoring the operation of the equipment, and carrying out process optimization and load adjustment for it. Initiate the maintenance procedures to ensure long-term operation following startup.
