In September 2022, Xinda signed a cooperation agreement with Leting Yikun Gas Co., Ltd. on crude krypton xenon gas extraction technology project. The signing of the contract marks a new step in the comprehensive utilization of energy, cost reduction and efficiency improvement of Hebei Xinda Group.

This project is the grain associated technology co., LTD. Hebei steel iron and steel industry research institute in the hebei xin da group, was established about mention mass transfer efficiency and innovation for the decision of the intellectualization management center "and" hebei xin da group, mass transfer efficiency and innovation for intellectualization management ascension management measure (trial) "and other documents of the spirit of guidance, to meet the needs of transformation and upgrading of the group, in line with the outstanding innovation leading role, Focusing on promoting a series of changes in corporate strategy, organization, process, management, etc., it promotes the group's transformation to low-carbon environmental protection, digital-wise lean, low-consumption and high-efficiency, realizes comprehensive digitalization and intelligence, and utilizes digital-wise technology to promote the in-depth development of the group's cost-cutting and efficiency work.

The krypton xenon extraction project is planned to be implemented in the oxygen production plant of Hebei Xinda Iron & Steel Group Co., LTD. It is an important step for Xinda to actively develop high value-added special gases. The project is expected to achieve an annual benefit of more than 72 million yuan.

As a rare gas, Krypton xenon is widely used in national economy, national defense construction, scientific research and People's Daily life. For example, krypton gas is mainly used in the electronics industry, electric light source industry, but also used in gas lasers and plasma flow; Xenon is mainly used in semiconductor, electric light source, aerospace, dark matter research, electronic chip manufacturing and other fields.

In late June, Hebei Steel Valley Iron and Steel Industry Research Institute learned through market and process research that liquid oxygen extraction technology of crude krypton and xenon has been successfully implemented in similar iron and steel enterprises. The main equipment for crude krypton and xenon extraction includes cold box system of fractating tower with imported filler, nitrogen circulation system and electric control system of the instrument. The liquid oxygen in the liquid oxygen storage tank is used for cryogenic separation principle. The distillation tower adopts the concentration process of imported Soerzer regular packing tower and nitrogen cycle, and the krypton xenon component in the liquid oxygen is concentrated as a product. Due to the high requirements of the separation and extraction process, the price is as high as gold. As an iron and steel enterprise, Xinda is rich in liquid oxygen. The crude krypton and xenon gas purification project will effectively alleviate the shortage of krypton and xenon resources in the domestic market after being put into operation in Xinda, which will have a positive impact on improving the company's profitability and promoting the brand awareness of Xinda.

In view of this, in-depth field survey in the valley of hebei steel iron and steel industry research institute, with sufficient demonstration solution manufacturer, think hebei xin da steel oxygen factory have thick krypton, xenon gas purification technology application conditions, successively with four solution provider for technical communication, negotiation, the two sides eventually come to an agreement, energy cooperation, The project construction, operation and maintenance shall be carried out by the solution provider. Hebei Xinda Iron and Steel shall provide the site and liquid oxygen raw materials, and distribute the crude krypton and xenon in proportion to maximize the company's interests.

In August, Hebei Steel Valley Iron and Steel Industry Research Institute and Operation and Development Department of Production, Operation and Management Center of the Group began to work together, giving full play to the professional and management advantages of both sides, and continuously providing ideas and suggestions for the comprehensive utilization of energy, cost reduction and efficiency improvement of the Group.

In the future, Xinda will continue intensive farming, deeply tap the potential of each process, focus on the application of advanced technology and advanced equipment in the industry, base on the reality of each process, reduce costs and increase efficiency, improve the group's comprehensive economic benefits, enhance the ability of scientific and technological innovation, and improve the group's intellectualization management level. All XINDA PEOPLE WILL BE UNSWERving, ALWAYS MAINTAIN THE image OF XINDA, SHOULDER the responsibility OF XINDA people, seize the good market window period of the good situation, in the transformation and upgrading of the moment, in order to build XINDA brand, start XINDA reputation, for the growth of XINDA industry contribution! Create a new situation of high quality development of Xinda!
