Industrial "carbon reduction" and development "green increase".
With the rise of carbon peak and carbon neutralization as a national strategy, the realization of the goal of double carbon is witnessing the new pulse of green development of manufacturing industry. General Secretary Xi Jinping pointed out in the report of the 20th National Congress of the Communist Party of China that "we should coordinate efforts to promote carbon reduction, pollution reduction, green expansion and growth, and promote ecological priority, conservation and intensive, green and low-carbon development". This is a clear requirement for coordinating the work of carbon peak and carbon neutralization, as well as a strategic path and key task to achieve the goal of "double carbon".
How to effectively reduce carbon?
"Carbon reduction should be the greatest mission of all industries in the future." Dong Shihong, chairman of Suzhou Shijing Technology Co., Ltd. (Hereinafter referred to as Shijing Technology), said in an exchange with China Cement Network that achieving the goal of "double carbon" is both a severe challenge and a major opportunity.
This is the belief and original intention of Shijing Science and Technology led by Dong Shihong to carry out the mission of environmental protection, and also their confidence and strength to help cement enterprises draw the ecological blueprint of the new era.
Steel slag + carbon dioxide = cement clinker? Ccement. Com/brandnewslist-1-1000121.2022
November 14, The world's first steel slag capture cement kiln flue gas CO2 production line for carbon sequestration auxiliary cementitious materials and low-carbon cement has been completed and put into operation in Jiyuan Zhonglian Cement Co., Ltd., Henan Province.
This production line is the first industrial production line in the world that uses steel slag to capture CO2 from cement kiln flue gas to prepare carbon sequestration auxiliary cementitious materials and low-carbon cement. The project uses steel slag dry method to capture and utilize CO2 in situ, while realizing the emission reduction of CO2 in cement kiln flue gas, effectively solves the problem of poor stability of steel slag and improves its activity, and prepares auxiliary cementitious materials with high activity and carbon fixation. It breaks through the bottleneck problem that restricts the large-scale safety and high value-added application of steel slag in building materials such as cement, concrete and aggregate for a long time.
"Jiyuan Zhonglian's project can effectively utilize steel slag as a resource, solve the problem of steel slag utilization and storage in iron and steel enterprises, and at the same time, under the action of catalyst, steel slag can solidify CO2 from cement kiln flue gas into stable carbonate solid." Achieve the effect of replacing cement clinker. Dong Shihong said.
Why is steel slag associated with carbon reduction? From Dong Shihong's inspiration to the landing of the project, Shijing Science and Technology has made great efforts.
According to the introduction, Shijing Science and Technology has set up a special scientific and technological company and a professional R & D team. The core technology of the project mainly relies on the two research platforms of the State Key Laboratory of Materials Chemical Engineering and the School of Materials Science and Engineering of Nanjing University of Technology. The research and development of the technology is led by Nanjing University of Technology. At present, the related core technology has been granted 8 national invention patents.

From fuel substitution, raw material substitution to carbon capture, utilization and storage, to the layout of new energy sources and the promotion of photovoltaic power generation, the cement industry has never stopped the pace of energy saving and carbon reduction, but it is undeniable. At present, many enterprises'attempts to reduce carbon emissions are still at the technical level, and need to be further popularized and promoted in the future. The carbon emission reduction project
of Jiyuan Zhonglian not only marks a new step in the application of CO2 capture and utilization technology and industrialization in China's cement industry, but also opens up a new way for the large-scale and safe application of steel slag in building materials and the realization of high-value resource utilization. It really realizes the win-win situation of iron and steel enterprises and cement enterprises, and achieves the dual goals of energy saving, environmental protection and circular economy.
From LCR to carbon reduction for more than ten years, the original intention of environmental protection remains unchanged
. In 2005, the State Council made the Decision on Implementing the Scientific Outlook on Development and Strengthening Environmental Protection, pointing out that environmental protection must be placed in a more important strategic position. In accordance with the requirements of fully implementing the scientific concept of development and building a harmonious socialist society, we should adhere to the basic national policy of environmental protection and solve environmental problems in development. Efforts should be made to enable the people to drink clean water, breathe clean air, eat safe food and live in a good environment.
In the same year, Shijing Science and Technology, which focuses on improving the quality of human settlements and realizing "poetic dwelling", was born. As a comprehensive R & D and manufacturing enterprise of environmental pollution control with high technology level, Shijing Science and Technology has never forgotten the original intention of environmental protection since its establishment, maintained the nature of green development, and composed a history of enterprise development with a pioneering and innovative attitude.
After more than ten years of development, Shijing Technology has developed into an overall solution provider for industrial pollution control, which integrates process pollution provention and control, terminal pollution control, trusteeship operation and maintenance, remote online monitoring and third-party detection services, and has significant competitive advantages and strong market competitiveness. It has formed a relatively complete business chain from scheme design, equipment manufacturing, system installation to value-added services, and can provide customers with one-stop comprehensive environmental protection services.
In particular, relying on a series of core technologies such as LCR low-temperature liquid catalytic denitrification technology and environmental pollution co-treatment technology independently developed by Shijing Science and Technology, and taking the pan-semiconductor industry as the market entry point, Shijing Science and Technology has accumulated rich industry application experience in this field and gained good market reputation.
The heart has wings, flying from the clouds in the sky; the dream is boundless, when the stars in the sea. The road of green innovation
from scratch, breaking the old and establishing the new, is doomed to be long and full of Rapids and dangerous shoals, which requires perseverance and courage to break through the barriers. But fortunately, whether it is LCR technology or steel slag carbon fixation technology, Shijing Technology led by Dong Shihong always strives to be the "only" and "first" that can not be duplicated in the environmental protection track. While realizing the rapid development of its own enterprises, it also promotes the green and high-quality upgrading of the cement industry.
