Sanning Chemical Continues to Pursue Low-Carbon and Energy-Saving Practices. Author/Source: Sinochem News Network. Date: August 27, 2021. Clicks: 16. On the afternoon of August 23, the launching ceremony for the 2021 Zhijiang City Energy-Saving Awareness Week and Low-Carbon Day was held, organized by the Zhijiang City Development and Reform Bureau and co-organized by Hubei Sanning Chemical Co., Ltd. At the meeting, a representative from Sanning Chemicals shared the company’s energy-saving experiences. It is reported that in recent years, Sanning Chemical has been continuously exploring energy-saving potential to improve its level of green manufacturing. The company makes great efforts to promote and apply advanced energy-saving process technologies. For example, the introduction of low-pressure ammonia synthesis technology, along with radial air intake design, results in a high ammonia conversion rate and a reduced amount of catalyst required, thereby significantly cutting down the electricity consumption for ammonia synthesis. The urea production plants utilize the world’s leading 5XX ultra-low energy consumption urea production process, which allows for the savings of 400 kilograms of steam per ton of urea produced. The application of a large number of new technologies has enabled an efficient and clean conversion of coal into ethylene glycol. Sanning Chemical continues to strengthen energy-saving technological upgrades. Focusing on the circular economy, it promotes closed-loop operations in production processes as well as the hierarchical utilization of energy, and carries out energy-saving reforms in those areas where equipment consumes a high amount of energy. It has phased out coal-fired hot air furnaces in its facilities, replacing them with systems that use recycled exhaust gas for combustion and waste heat as a heating source, thereby reducing coal consumption while improving the level of clean production. The boilers use new water treatment agents, which help maintain stable steam quality while increasing the overall thermal efficiency of the system, generating annual savings of over 5 million yuan. The company is also continuously advancing its digital transformation to improve the informatization and intelligence level of energy management. They established a demonstration project for online monitoring of energy consumption in Yichang City, achieving a level of energy consumption monitoring equivalent to tier 3. They developed balance models for energy sources such as steam, water, and electricity, enabling centralized and visual management of energy use throughout the entire process. Advanced control systems have been implemented for all major units, including those used in the production of synthetic ammonia, urea, caprolactam, sulfuric acid, and boilers.
