Fulfilling the social responsibilities, Implementing Energy saving and Emission reduction--- Building new Xingtai Iron & Steel Corp.,Ltd of “cyclic development”
Xingtai Iron & Steel Corp.,Ltd earnestly implemented the energy saving and emission reduction policy of “carefully planning, responsibilities fulfilling, tightly monitoring, strictly implementing” and the management ideas of “dealing both with small and big things”, started from three aspects of process optimization, backward elimination and use of advanced energy-saving and emission-cutting technology, and put the comprehensive utilization of resources, energy saving and environmental protection in the first place. The company adjusted product structure, carried out the work for energy saving and emission reduction, implemented cleaner production, undertaken the social responsibilities of energy-saving and environmental protection to develop a cyclic economy, and constructed a sustainable developing enterprise of resource-saving and environment-friendly type for a harmonious relationship between the enterprise and nature. Because our self-improvement mechanism was perfect, in the face of COVID-19 pandemic and production restriction, Xingtai Steel researched scientifically, handled calmly and work together to achieve the expected energy targets.
Actively implementing energy conservation project，Improving resources utilization sufficiently
Xingtai Iron & Steel Corp.,Ltd has actively carried out energy saving and comprehensive utilization of resources and built 280,000 m3 Gas tank which can recover 4,100,000,000 m3 of gas per year to achieve zero-emission of gas. Xingtai Iron & Steel Corp.,Ltd has successfully implemented projects such as BF rich gas power generation,Coke dry quenching power generation,Sintering waste heat power generation,TRT, BPRT,Screw for steam power generation, Variable frequency conversion,efficient energy saving pump, green lighting and other projects. Through gas comprehensive utilization project and TRT power generation project，Xingtai Iron & Steel Corp.,Ltd still has a capacity of generating 363 million kwh power under the circumstance of limiting the production in 2021. In order to further increase the recovery efficiency, our company started to build 130 Tons Boiler for high-temperature and super high pressure waste heat generation project and completed it 10 months later. Then the project came into use on September 13th, 2018. After the project is put into use, it greatly increased the efficiency of gas utilization. In 2021, Xingtai Steel has generated 204.8176 million kWh power. The unit consumption of gas for thermoelectric power generation decreased from 4.63 m3/kWh to 3.13 m3/kWh.
Xingtai Iron & Steel Corp.,Ltd has built an Energy Management Centerand which has functions of energy management such as automatic data acquisition, online monitoring, energy balance scheduling and planning, energy performance and energy analysis. On the basis of remote monitoring and visual management of company energy and production to implement information shared, unified command, concentrated interlinked, to meet flat , real-time of, global, and comprehensive requirements, The Center reduced coordination links, improved efficiency. The Energy Center promoted the company production and the various energy of reasonable using, and implemented the energy saving mode from single equipment energy-saving to integrated (System) energy-saving.
Xingtai Steel built energy management system and passed external certification. Xingtai Steel passed the new certification in Feburary, 2022. The system conforms to the requirements of GB/T23331-2020 of the energy management system. According to the standard requirements of energy management system in daily, carrying out inspection and review, implementing continuous improvement, to promote the company's energy management by compliance evaluation. The energy consumption of each process of the company has completed the requirements of Hebei province's energy consumption limit, and the energy saving target of the government has been completed, which has been rated as an advanced unit for energy conservation for several years.
In the production process, Xingtai Iron & Steel used advanced technologies to achieve the adjustment of product structure, and so controls the energy consumption and pollution from the beginning. Xingtai Iron & Steel implements the developmental strategy of “prefect, expert and stronger”, does not expand its capacity, imported international advanced technologies and equipment, and eliminates all the old technologies with high energy consumption. The pollutant emission reduction was realized by optimizing the productive technology and intensifying process control.
Intensifying monitoring of the facilities to ensure the stable operation
Xingtai Iron & Steel Corp.,Ltd set up a perfect institution for environmental monitoring, and equipped various monitoring instruments such as spectrophotometer, photoelectric analytical balance, all-weather atmospheric continuous monitoring system, the hydrostatic balance flue gas concentration detector, sound level meters, precision pH meter, dust concentration detector, atmospheric sampling, carbon monoxide detector. All the posts of the company are monitored daily, weekly, ten days, monthly, quarterly. Control measures are operated for all the environmental protection facilities. Emergency plans were made for all the suspected environmental pollution region. A perfect check-up system was drafted. The important indicators are monitored on line.An on line monitoring equipment was installed on the wastewater outlet and head of sintering machine, and connected with the department of environmental protection. Surveillance video devices were installed in the steel, iron, coking region to ensure all the pollutants discharging meeting the standard.
Following our country’s calls, reducing emission with all the strength, and stabilizing the achievements of emission reduction
Xingtai Steel actively implements the reqiurements in “Notice on the Management of Company Reporting on Greenhouse Gas Emission in 2022” and “Guidelines for Company Reporting on Greenhouse Gas Emissions (Trial)”. Xingtai Steel strengthens the management of data on greenhouse gas emission, further refines the verification procedures and clarifies the verification points. Moreover, we strictly implement the requirements at provincial and municipal levels, complete the report on Greenhouse Gas Emission for 2021 on time and cooperate with the relevant verification work. Xingtai Steel built a new sewage treatment plant in 2011 to realize recycle after depth treatment by collecting, producing the standard of discharge of wastewater treatment for each unit by conventional treatment such as precipitation, filtration, disinfection and ultrafiltration, reverse osmosis, and to realize the zero discharge of industrial wastewater.In 2012, the SDA facilities with Danish technology were built in the sintering machines. In 2022, the SCR denitrification facilities were newly installed to desulfurize and denitrify the sintering waste gas, achieving ultra-low emission of the waste gas. All the clean level of production of the company met the first and second level of the national standard for clean production, and was advanced in the nation.
