Weihua Company takes targeted measures to ensure stable growth and achieves synergistic efficiency gains. Author/Source: Weihua Group Date: 2022-04-02 Clicks: 13 In the first quarter of 2022, Weihua Company focused on meeting the goals of stable growth, adopting an attitude of \"seizing every moment\", a spirit of innovation, and a pragmatic approach, and embarked on a high-quality development path centered on energy conservation, carbon reduction, water savings, and emission cuts. The company produced a total of 374,800 tons of urea, methanol, and dimethyl ether, achieving a successful start to the year; in January alone, 57,200 tons of urea were produced, setting another record. Precise management to ensure stable high-load production. To achieve high-quality operation under high loads, the production management department continuously improves the operational quality of the facilities ； Improve the \"Production Unit Operation Analysis Report\" to accurately identify the bottlenecks in terms of water consumption, electricity consumption, coal consumption, and raw material usage during unit operation; then take targeted measures by implementing technical improvements, innovation, and equipment upgrades in order to reduce the unit cost of products ； Strengthen the planning, organization, coordination, and control functions of production scheduling and maintenance scheduling to effectively reduce the frequency of unplanned shutdowns and load reduction incidents ； Dynamically update the “List of Equipment with High Failure Rates in Production Facilities” to address equipment issues specifically and eliminate weak points ； Strengthen the operation management of gasifiers and boilers, continuously improve the list of backup units, and strive to extend the operational cycle of these two types of equipment ； Standardize the self-assessment of production management, strengthen execution capabilities, and improve basic management levels to lay a solid foundation for the stable operation of the facilities. By implementing targeted measures, the company has achieved significant results in water conservation and emission reduction. Aiming to become a **model enterprise in water conservation, it actively carries out technical upgrades to reduce water use, makes full use of non-conventional water sources such as wastewater, rainwater, and reclaimed water, thereby improving the efficiency of water utilization and reducing water consumption per unit of product. The reuse rate of reclaimed water across the entire company has been increasing, while the amount of wastewater discharged has been decreasing. By carrying out special initiatives such as the \"No Pollutants Beyond the Designated Areas\" campaign, efforts to address leaks and spills, and the \"Weihua Water Conservation Awareness Month\", the ideological foundation for all employees to practice water conservation is strengthened. Strengthen management of water conservation and emission reduction by tracking throughout the entire process the company’s usage of water for consumption, drainage, and recycled water. Implement a \"sealing\" system for the valves in the sewage pipelines that lead directly to the production units, thereby forcing the production workshops to take effective measures to eliminate or reduce sewage emissions ； Strengthen the operation management of cooling tower fans, strictly control the feed water temperature of the three circulating water systems, and continuously improve the reuse rate of circulating water. Increase investment in water-saving upgrades, and continue to advance the construction of projects aimed at improving the systems for recycling reclaimed wastewater from neutralization tanks as well as for pre-treating recycled water, so as to ensure that all such water is recycled. Lean innovation: creative ways to save energy and reduce carbon emissions. With a resilient determination to innovate and take the lead, the company has embarked on a new journey toward energy savings and carbon reduction. Implement a project for the comprehensive utilization of gasified fine slag through dehydration and drying, in order to address issues such as the high water content in the ash sludge from gasification units, the inability to recycle residual carbon resources, and the significant environmental pollution caused by landfilling, thereby improving the company’s level of comprehensive utilization of solid waste resources. By using high-quality low-sulfur coal, adjusting the amount of denitration agents used, improving the stability of boiler operation, and exploring advanced and suitable technologies, the company has managed to reduce the emissions of volatile organic compounds, particulate matter, and nitrogen oxides by at least 10%, while keeping the emission concentrations of particulate matter at no more than 5 mg/m3, sulfur dioxide at no more than 17.5 mg/m3, and nitrogen oxides at no more than 25 mg/m3. Technical research and exchanges are carried out to address issues related to inefficient energy use, with the aim of improving energy utilization efficiency through the optimization of process operations and scheduling. Strengthen daily monitoring of the \"0\" opening setting of the three sets of pressure relief valves and vent valves in the heating network ； Building on the approach of generating power during off-peak times and drawing power during low-demand periods, this involves a mode in which equipment that operates intermittently is kept in standby during peak electricity hours and activated during low-demand hours ； Thoroughly investigate the feasibility of using process waste steam from boilers with self-provided generator sets. From the perspective of dual control over energy consumption, strive to draw as much electricity from the external power grid as possible, and use boiler steam for power generation only when necessary or to the minimum extent, so that the limited coal consumption quota can be utilized effectively. At the same time, third-party agencies are invited to conduct in-depth energy-saving diagnostics of the production facilities, providing scientific, reasonable, and actionable recommendations for energy-saving upgrades as well as suggestions for adjusting energy consumption processes. By taking into account the actual conditions of the company’s production facilities, these efforts aim to fully exploit the potential for technological improvements in energy savings and carbon reduction, thereby further reducing the overall energy consumption of the company’s main products.
