Jiangxi Xinlianxin: Contributing to Ecological Protection and Green Agriculture (IV) Author/Source: Sinochem New Network Date: 2022-07-12 Clicks: 12 Adhering to the safety standards and environmental protection guidelines, strengthening the concept of comprehensive environmental protection and safety for all employees, and integrating the company’s internal cycles into the broader regional cycles. Shang Dewei, general manager of Jiangxi Xinlianxin Company, said that the company aims to become a benchmark for safety and environmental protection in areas south of the Yangtze River. In terms of safety, it has adopted DuPont’s safety management practices, established an evaluation system for autonomous safety management, and promoted the integration of various related mechanisms to achieve standardization in safe production. In areas with high safety risks, the company conducts special inspections, audits, thematic meetings, and daily checks to enhance safety awareness and fulfill its primary responsibilities ； Strengthen the construction of a dual-prevention system, divide into analysis units, identify and assess risks, sort out control measures, and implement hierarchical control ； Strengthen the intelligent development of safety management, achieve intelligent inspection, and make maintenance operations digital, standardized, and visual. President Shang said that in terms of environmental protection, Jiangxi Xinlianxin imposes extra pressure on itself, aiming for ultra-low emissions; on top of meeting national and local standards, it adopts even stricter internal control criteria within the company. For example, by employing technologies such as integrated desulfurization and whitening using ammonia, low-nitrogen combustion combined with SCR denitration, and bag filter dust removal, the dust emission concentration in boiler flue gas is kept below 5 milligrams per standard cubic meter, the nitrogen oxide emission concentration is below 35 milligrams per standard cubic meter, and the sulfur dioxide emission concentration is below 15 milligrams per standard cubic meter – all of which are below the ultra-low emission standards set out in the \"National Plan for Ultra-Low Emission and Energy-Saving Upgrades in Coal-Fired Power Plants.\" These measures enable a reduction of 120,000 tons of dust emissions, 1,200 tons of nitrogen oxide emissions, and 6,000 tons of sulfur dioxide emissions per year ； Low-temperature distillation technology is used to recover carbon dioxide from vent gases; a carbon dioxide recovery facility with an annual capacity of 100,000 tons has already been built, and a second facility with an annual capacity of 300,000 tons for carbon dioxide recovery and 30,000 tons for dry ice production is currently under construction. It is expected that once operational, these facilities will enable the reduction of 400,000 tons of carbon emissions per year. Huang Huiyong, executive deputy general manager of Jiangxi Xinlianxin, said: “The water treatment systems produced by Jiangxi Xinlianxin utilize an efficient nitrogen removal wastewater treatment process, which reduces COD emissions by more than 2,500 tons per year and ammonia nitrogen emissions by more than 860 tons per year.” ； By employing reclaimed water technology, the wastewater recycling process enables savings of 2.5 million tons of water per year. Additionally, 300,000 tons of coal ash and slag generated by the gasification and boiler systems can be used in the production of building materials. This approach not only ensures that environmental protection efforts within the company are carried out effectively but also maximizes resource utilization. ”
