NEWTEK : A Leader in Gas Technology​

Diversified Technology Coverage, Building a Strong Technology Matrix​

As an enterprise focusing on the gas field, NEWTEK has a diversified and advanced technical system, covering PSA technology, cryogenic technology, membrane separation technology, and CO₂ capture technology.​

●In terms of Pressure Swing Adsorption technology, the group has developed pressure swing adsorption equipment suitable for various working conditions based on the principle of selective adsorption of different gases by adsorbents. This technology can operate at room temperature and quickly separate high-purity gases through periodic pressurized adsorption and decompressed desorption processes, meeting small and medium-sized application scenarios with high requirements for gas supply response speed, such as small-scale medical oxygen production and laboratory gas supply.​
 

●In the aspect of cryogenic technology, the group uses the principle of low-temperature rectification to cool air to a liquid state, and then separates it according to the difference in boiling points of each component. Through independently developed key equipment such as high-efficiency rectification towers and low-temperature heat exchangers, it has realized large-scale and high-purity preparation of oxygen, nitrogen and other gases. At present, more than 9,000 sets of the group's systems have been installed worldwide, among which cryogenic gas production equipment operates stably in large-scale projects such as the 4×40,000Nm³/h air separation project in Peru and the 51,000Nm³/h air separation project in the Philippines, ensuring the large-scale gas demand of industries such as iron and steel and chemical industry.​

●Membrane separation technology relies on high-performance polymer membrane materials developed by the group, using the difference in permeation rates of different gas molecules in the membrane for separation. This technology has simple equipment, convenient operation, and can realize continuous production. It is suitable for scenarios where the gas purity requirement is not extremely high but stable gas supply is needed, such as nitrogen replacement in food packaging and purge gas preparation in the electronics industry.​

In CO₂ capture technology, the group has developed various capture processes such as chemical absorption and physical adsorption, which can efficiently capture carbon dioxide from gas sources such as industrial tail gas and combustion flue gas. The captured carbon dioxide can be used in fields such as food processing and oilfield flooding, realizing resource reuse.​
 

Technical Achievements Demonstrate Strength​

By virtue of in-depth research, development and application of the above technologies, the group has made many technical achievements. In terms of patents, it owns a number of core patents related to key links such as gas separation, purification and capture. In project implementation, it has successfully completed a number of large-scale gas supply projects with industry benchmarking significance, covering multiple industries such as metallurgy, chemical industry and energy, providing stable and reliable gas solutions for customers in different regions around the world.​

In terms of technological innovation transformation, the group continues to transform laboratory research results into actual productivity. For example, the optimization and upgrading of cryogenic equipment, by improving the refrigeration system and rectification process, reduces equipment energy consumption and improves gas production efficiency; the upgrading of automatic control of PSA equipment realizes more accurate adsorption and desorption operations, improving gas purity and equipment stability.​

Leading the Industry's Sustainable Development​
 

In terms of sustainable development, the group actively plays a leading role. Through the synergy of CO₂ capture technology with cryogenic, PSA and other technologies, it helps industries such as iron and steel and chemical industry reduce carbon emissions and achieve low-carbon transformation. For example, in some iron and steel enterprise projects, cryogenic oxygen production is combined with CO₂ capture. While providing oxygen for blast furnace oxygen-enriched smelting to improve production efficiency, it captures carbon dioxide generated during smelting, reducing greenhouse gas emissions.​

In energy utilization, the group's membrane separation and PSA technologies provide gas for industrial production in a low-energy-consuming way, which significantly reduces energy consumption compared with traditional high-energy-consuming gas preparation methods. At the same time, the group actively participates in the formulation of industry standards and technical exchanges, promotes its advanced gas technology and sustainable development concepts to the entire industry, and drives the entire gas technology field to develop in a more efficient and environmentally friendly direction.​

In the future, NEWTEK will continue to deepen research and development in PSA technology, cryogenic technology, membrane separation technology, CO₂ capture technology and other aspects, and continue to lead the development of the gas technology field with technological innovation and diversified applications, contributing to the sustainable development of global industry and society.
