Guide:The steel industry is an important basic industry of the national economy, and it is also a key industry in energy consumption and carbon dioxide emissions. On June 7, the National Development and Reform Commission and other departments issued a notice of the "Special Action Plan for Energy Conservation and carbon Reduction in the Steel Industry". The action plan aims to further tap the energy saving and carbon reduction potential of the steel industry, accelerate the energy saving and carbon reduction transformation of the steel industry and the renewal of energy use equipment, and support the completion of the "14th Five-Year Plan" to reduce energy intensity binding indicators.

Suzhou Since Gas Technology Co., LTD. (hereinafter referred to as "Since Gas") since its establishment in 2004, after more than 20 years of technology accumulation and market work, has provided more than 8,000 industrial gas equipment solutions for customers in more than 40 industries, of which the steel industry is more widely used. In the steel industry, hydrogen is mainly in the form of heat source and reducing agent, after the furnace annealing treatment, a large number of waste hydrogen and exhaust gas will be discharged into the atmosphere, not only causing a huge waste of energy, but also will cause a certain amount of environmental pollution, as a clean energy of hydrogen energy, is promoting the traditional steel smelting industry to green low-carbon transformation.

Hydrogen smelting technology is a kind of smelting technology based on physical and chemical principles, using hydrogen to reduce metal oxides. With the proposal of China's "carbon peak" and "carbon neutral" strategy, the development and utilization of hydrogen energy has been pushed to the fast lane, and a series of hydrogen metallurgy technology path exploration has been launched everywhere. In recent years, Since Gas has been committed to the development and application research of green hydrogen energy related equipment, and launched economic hydrogen production solutions: Integrated methanol to hydrogen reformer skid and low temperature with medium pressure green ammonia cracker to hydrogen.

Hydrogen recycling is an important link in the steel production process, which is of great significance for reducing environmental pollution and improving energy efficiency, and is also an effective way to promote the green low-carbon transformation of the steel industry and move towards high-quality sustainable development. Hydrogen recovery skid independently developed by Since Gas (National invention patent No. : 2018100947048), the waste hydrogen/exhaust gas is cooled, washed and dedusted, and most of the water in the exhaust gas is condensed into the Roots fan for pressurization, and the waste hydrogen after pressure treatment by the fan is entered into the hydrogen purification device or PSA for secondary treatment, so that the oxygen content and dew point of the gas are reduced to the production requirements. The purified hydrogen is re-used as the raw material hydrogen, and the recovery rate of waste hydrogen can reach more than 90%, which greatly reduces the hydrogen cost of customers, reduces environmental pollution, and improves energy utilization efficiency.

At the same time, in the steel industry, we can often see the application of nitrogen. Nitrogen is mainly used as a protective gas, such as steel rolling, zinc plating, chromium plating, heat treatment (especially thin steel plate) and continuous casting process, Since gas research and development of the upgraded version of high stability, low energy consumption PSA nitrogen generator, with air as raw material, customers can choose according to the actual needs of one step to produce high purity nitrogen, hydrogenation purification two steps to produce high purity nitrogen, hydrogen purification two steps to produce high purity nitrogen and other products. High purity nitrogen can be provided quickly.

As a pioneer in China's gas equipment industry,

Since Gas always adhere to provide customers with the most valuable gas equipment solutions,

Work with all customers to achieve sustainable development and green carbon reduction!
