Luanan Coal-Based Oil Company had a successful start to the first quarter in terms of urea and ammonia production. Author/Source: Luanan Coal-Based Oil. Date: 2022-04-02. Clicks: 16. The company managed to produce 82,563.6 tons of urea and 62,031.3 tons of liquid ammonia during the first quarter, marking a successful beginning that paved the way for a new phase of high-quality development for the company. The company’s highest urea production in March reached 1,036.15 tons per day. This is the result achieved by the company through reducing raw material costs and improving operational efficiency. Since the first quarter, the company has actively carried out trial burns of different coal types, conducting continuous tests and analyses. Based on the results, it evaluates the economic viability of various coal types, thereby formulating precise coal blending plans to reduce raw coal losses. By creating EXCEL tables for the economic analysis of costs associated with different coal types, it is possible to adjust the coal mix in response to price changes. By comparing the economic outcomes of testing different coal prices, better guidance can be provided for formulating the most optimal plan for purchasing coal. In addition, the company makes coordinated scheduling arrangements, actively optimizes working hours in response to changes, improves work efficiency, clarifies optimal start and completion times, and oversees the improvement of responsibility oversight processes and their implementation and verification. It strives to achieve accurate information, clear responsibilities, timely responses to changes, and high efficiency. The company carries out technological upgrades from multiple perspectives, with a focus on efficiency and a culture of cost optimization. Just the energy-saving adjustments made to the 3# nitrogen compressor and the urea cycle water pump alone have helped to reduce the load on these equipment, resulting in annual savings of 1,174,979 yuan in electricity costs. Furthermore, through repeated nitrogen level measurements at various locations on site and design adjustments based on those measurements, the interlock technology related to pump reduction was successfully developed; this approach also enabled the company to save 2,233,800 yuan per year. To reduce labor costs, the company also optimized the \"boiler startup process and the system for feeding materials into the boiler.\" It cleared the idle slag storage areas in the boiler and improved the material feeding system, allowing the materials to be stored in these areas for long periods; they are then fed into the boiler furnace by the boiler’s coal feeder just before it starts operating. This approach significantly reduced the time required for material feeding, saving 45,476 yuan per year in labor costs and generating an annual production value of 1,008,000 yuan. In terms of focusing on efficiency, to increase urea production, the company held specialized meetings on urea production capacity, pooling ideas and conducting discussions to address various issues that affected production, such as the impact of fluctuations in 51#CO2 on urea production capacity. Numerous effective measures were developed to boost production, enabling the urea production facility to reach a stable operating level of over 1,000 tons per day right from the start. While ensuring production volume, the company also focuses on expanding sales channels for its products, striving to improve and enhance product quality. It forms a professional and competent sales team, emphasizes customer service, standardizes processes, and sets clear goals, with the aim of achieving profitability at the earliest possible time. The company is fully aware of the importance and complexity of the dual control measures regarding energy consumption. In light of the actual conditions of the enterprise, it conducts comprehensive research, coordinates efforts to advance relevant actions, and implements effectively the company’s plan for controlling the specific energy consumption per unit of liquid ammonia produced. By adjusting the pressure of the purified CO2 flash vapor, the composition of the gas is controlled to ensure the purity of the raw CO2 ； It maintains stability in the load of the urea production system as well as in the steam pressure in the pipeline network, thereby providing a stable external process environment for the urea plant to adjust the conversion rate ； Strictly control the ammonia-to-carbon ratio and water-to-carbon ratio in the high-pressure system, as well as the parameters of the high- and low-pressure absorption systems, to reduce the amount of gaseous ammonia released and improve the recovery rate ； In terms of management, the concept of energy conservation and cost reduction was instilled among team members; strict assessment and reward systems were implemented for compliance with process standards. The production philosophy that reducing consumption leads to increased efficiency was emphasized, which resulted in a downward trend in the per-unit consumption of liquid ammonia from month to month. In January, the maximum daily production volume of liquid ammonia reached 704.2 tons.
