The flue gas treatment process for high-tower granulation at Jiangzhong Energy has been upgraded once again! Author/Source: Shanghai Jingye Environmental Protection. Date: 2021-06-23. Clicks: 8. After two years, Xinjiang Zhongneng Wanyuan Chemical Co., Ltd. (hereinafter referred to as Xinjiang Zhongneng) signed a contract with Shanghai Jingye Environmental Protection Energy Technology Co., Ltd. (hereinafter referred to as Shanghai Jingye) to work together on the treatment of exhaust gases generated in the second-phase 600,000-ton production project of Xinjiang Zhongneng. The new type of exhaust gas purification system provided by Shanghai Jingye will be used to develop a green granulation process; the project is expected to come online in 2022. This is another collaboration between the two parties on a new project, driven by their recognition and satisfaction with the results of the previous project – namely, the environmental improvement upgrades to the exhaust gas treatment system of the original granulation tower that were carried out in 2019 by Xinjiang Zhongneng in conjunction with Shanghai Jingye. http://img.yf116.cn/image/img/20210623/1046253878552.jpg New green high-tower granulation process. In recent years, Shanghai Jingye has conducted thorough market research, incorporated the reasonable suggestions from clients and design institutions, and optimized its design and production processes to develop a brand-new generation of ‘new green high-tower granulation process’. This process aims to enhance Xinjiang Zhongneng’s environmental competitiveness by providing forward-looking environmental protection solutions. The new type of green tower granulation process—that is, at the initial stage of designing the granulation tower, both parties engage in joint design efforts to integrate Shanghai Jingye’s industry-leading “tail gas purification system for tower granulation” into the preliminary design of the granulation tower. This ensures that the process flow and parameter design are perfectly aligned with the overall granulation design. This approach enables the production of high-quality granulated products, while also promoting environmental protection and energy savings. Moreover, by utilizing Shanghai Jingye’s patented dry-process technology, it offers great foresight: not only does it meet current environmental emission requirements, but it also prevents the release of moisture-containing vapors and controls ammonia emissions, thus aligning with future goals for air pollution control. The new green high-tower granulation system offers more advantages compared to traditional retrofitting methods: 1. The equipment is integrated into the tower structure, resulting in greater structural strength ； 2. The process flow and parameter design of the efficient exhaust gas purification system are taken into account from the initial stage of high-tower granulation design, enabling better coordination and superior granulation results ； 3. The volume of on-site construction work has decreased, and the difficulty of construction has reduced ； 4. With the latest design and layout, it is expected to offer higher operational stability and further reduced energy consumption. ‘The ’High-Tower Granulation Exhaust Gas Purification System’ has been recognized by Xinjiang Zhongneng’s customers. For its new 600,000-ton urea production project, Xinjiang Zhongneng has once again partnered with Shanghai Jingye to develop a new type of green high-tower granulation system; this collaboration is based on the satisfactory actual performance of Shanghai Jingye’s patented dry-process technology – the ’High-Tower Granulation Exhaust Gas Efficient Purification System’. The dry process avoids the emission of water vapor containing impurities and controls the escape of ammonia, making it a more advanced environmental protection technique. It represents the new direction for air pollution control and is the trend for future development. In 2019, in order to completely eliminate pollution during the granulation process, Xinjiang Zhongneng adopted the ‘High-Tower Granulation Exhaust Gas High-Efficiency Purification System’ provided by Shanghai Jingye Environmental Protection for environmental improvement efforts, and it was put into operation in the same year. After two years of operation over a long period, the ‘High-Tower Granulation Exhaust Gas High-Efficiency Purification System’ has withstood the harsh cold and scorching heat in Xinjiang; the system operates stably, and its emission levels are well below the specified standards. This system has made a significant contribution to helping enterprises reduce energy consumption and emissions, thereby enhancing their environmental competitiveness. The completion of this project will greatly reduce the emission of highly polluting organic dusts and VOCs (with annual emissions dropping from over 2,000 tons to less than 50 tons), as well as saving more than 100,000 tons of fresh water per year.
