Industrial Gas Purification Under the 15th Five-Year Plan Energy Deployment
The recently released proposals for the 15th Five-Year Plan place energy security and the green, low-carbon transition in a prominent position. The plan explicitly states that it is necessary to... Building a modern energy system that is clean, low-carbon, safe, and efficient. and, and Promote the high-end, intelligent, and green transformation of traditional industries. 。
This strategic orientation will pose new technological demands on multiple industrial sectors, among which the purification and drying of industrial gases—as a fundamental process step—will see its importance further enhanced.
I. The Need for Energy Transition and Industrial Upgrading
The “15th Five-Year” Plan proposes that energy deployment should focus on three levels:
• Energy Security: Strengthen the capacity to ensure domestic energy production and improve the energy reserve system.
• Structural transformation: Steadily advance the development of non-fossil energy sources and promote the clean and efficient utilization of fossil energy.
• Industrial upgrading: Drive the manufacturing sector toward the high end of the value chain through technological innovation.
Under this framework, the development of key sectors such as new-energy equipment manufacturing, advanced nuclear power, and the hydrogen energy industry—as well as the green transformation of traditional industries like steel and petrochemicals—have all placed stricter demands on the quality of process gases.
II. Gas Purity Affects Technical Performance
Each link in the hydrogen energy industrial chain also relies on high-purity gases:
Hydrogen production end: Hydrogen production is the starting point of the hydrogen energy industry chain. Although different hydrogen production pathways vary significantly in terms of feedstock and processes, their ultimate goal remains the same: to produce high-purity hydrogen gas. Meanwhile, some processes also require high-purity auxiliary gases to ensure reaction stability.
Hydrogen end: Hydrogen applications span multiple fields, including fuel cells, industrial hydrogenation, metallurgy, and more. The purity requirements for hydrogen vary significantly across different scenarios due to differences in equipment characteristics and reaction mechanisms. Impurities can lead to performance degradation or pose safety risks.
Storage and Transportation End: Hydrogen storage and transportation connect the hydrogen production and utilization stages, and primarily encompass four methods: high-pressure gaseous storage, liquid storage, solid-state storage, and pipeline transportation. High-purity hydrogen can effectively avoid equipment corrosion and leakage risks caused by impurities, while also reducing losses during storage and transportation.
From hydrogen production Source purification To storage and transportation Safe Transportation , and then to using hydrogen “Efficient Application” The purity specifications for high-purity gases are progressively enhanced, and the purity requirements for auxiliary gases are equally stringent as those for hydrogen—any failure to meet the purity standards at any stage can lead to reduced efficiency across the entire industrial chain, increased costs, and even safety risks. Therefore, high-purity gas technologies (including purification, detection, and supply) represent one of the core supports for the large-scale development of the hydrogen energy industry.
III. Gas purification helps save energy and reduce carbon emissions.
The “intelligent and green” direction emphasized in the 15th Five-Year Plan is reflected in the gas purification sector as follows:
In the steel industry, deep purification of recovered gases (such as converter gas and blast furnace gas) can achieve:
• Remove corrosive impurities such as organic sulfur and chlorides to extend equipment lifespan.
• Reduce moisture content and improve the efficiency of utilizing the calorific value of coal gas.
• Create the necessary conditions for subsequent chemical utilization.
In the petrochemical industry, precise purification of feed gases can:
• Reduce catalyst poisoning and extend service life
• Reduce the incidence of adverse reactions and improve product yield.
• Achieve resource utilization of exhaust gases and reduce emissions.
In response to the trends of “intelligentization and greenness,” gas purification technology itself is also advancing. The integration of online analytical instruments with digital control systems makes real-time monitoring and predictive maintenance possible, thereby optimizing energy consumption and reducing unexpected downtime. Solutions are becoming increasingly sophisticated, with customized designs and modular equipment tailored to different industries and specific gas components, making rapid deployment and flexible adjustments easier than ever. Meanwhile, energy-saving designs and the exploration of new adsorption materials continue to push the boundaries of energy efficiency forward.
The 15th Five-Year Plan has brought clear technological demands and market opportunities to the industrial gas purification sector, and gas drying and purification technologies will face even broader application prospects.
This sets new expectations for practitioners:
• Gain a deep understanding of the process requirements across different industries and provide tailored solutions.
• Continuously pursue technological innovation, especially in energy conservation, consumption reduction, and intelligentization.
• Establish and improve a comprehensive service system to ensure the stable operation of customer production.
Although high-quality industrial gas supply does not often attract public attention, it serves as a fundamental guarantee for the high-quality development of numerous industries. Against the backdrop of energy transition and industrial upgrading, the professional value of gas drying and purification technologies will be further highlighted.
