Capping of the granulation tower for Hebei Dongguang Chemical’s 540,000 tons/year urea production project

Thread Content

On the morning of October 31, at the site of the 540,000 tons per year urea production facility upgrade project aimed at reducing energy consumption and carbon emissions, carried out by Hebei Dongguang Chemical Co., Ltd. (hereinafter referred to as “Dongguang Chemical”), the pouring of the final batch of concrete was completed, marking the successful completion of the construction of the main structure of the 123-meter-tall urea granulation tower. With this, decisive progress has been made in the civil engineering works of this project, which has now fully entered a new phase focused on completing the civil work and installing equipment. It is reported that since the construction of the granulation tower began in May this year, it has had to endure various challenges such as construction during the rainy season, work in high temperatures, and continuous rainfall in autumn. Faced with numerous challenges, all participating parties organized their efforts scientifically and worked closely together to continuously optimize the construction plans, striving to make the most of the available time for construction. Especially during the critical phase of slipform construction, all the builders worked day and night, operating continuously for 24 hours, and ultimately achieved the topping-out goal nearly a month ahead of schedule, thereby gaining valuable time for the overall progress of the project. Guo Jianming, general manager of Dongguang Chemical, said at the ceremony: “The successful completion of the granulation tower is the result of the wisdom and hard work of all the constructors; it is a vivid example of efficient collaboration and diligent effort among various teams.” ”He emphasized that the subsequent construction tasks remain arduous, and all parties must continue to adhere to the principles of \"safety first and quality foremost,\" work together efficiently and advance tasks with precision, so as to achieve the goal of completing the water linkage test runs before winter in 2026 on a high-quality and high-standard basis, and ensure that the project is delivered on schedule and to high standards. This project is a key initiative by Dongguang Chemical in actively responding to the policies regarding large-scale equipment renewal and technological upgrading in the manufacturing sector. With a total investment of 580 million yuan, it is considered a key project in Cangzhou City. The project adopts the \"high-efficiency urea synthesis process technology\" which is included in the **Ministry of Industry and Information Technology’s Recommended Catalogue of Energy-saving and Carbon-reduction Technologies and Equipment in the Industrial and Information Technology Sector\"; by upgrading the existing facilities with this technology, the energy efficiency and the overall utilization rate of resources are significantly improved. It is reported that the new components of this project include not only granulation towers, but also CO₂ compression plants, the main urea production unit, urea loading docks, a packaging building, as well as various supporting utility systems. Once the project is put into operation, it will achieve significant goals in terms of energy savings, consumption reduction, and carbon emission cuts; the overall energy consumption for urea production will reach the advanced levels typical of the fertilizer industry. At the same time, process optimization and efficient recovery and utilization of carbon dioxide provide strong impetus for achieving green and low-carbon development.
