A lithium salts factory run by Chinese miner Xinjiang Nonferrous Metal Group, that will be part of the world’s biggest integrated project for the mining, separation and smelting of lithium salts, kicked off construction in the country’s northwestern Xinjiang Uyghur Autonomous Region recently. The facility in Luofu county, Hotan prefecture will have an output of 100,000 tons of lithi...

VPSA and PSA oxygen generation equipment are primarily adopted for industrial oxygen production. Pressure Swing Absorption (PSA) oxygen generation technology is a new gas separation process that uses molecular sieves as the adsorbent to separate gas mixtures based on the difference in adsorption properties of molecular sieves for various gas molecules. With air as the raw material, i...

December 28, 2022, the Chinese Society for Metals (CSM) released the Technical Requirements of VPSA Oxygen Generation for Blast Furnace Ironmaking (T/CSM-44-2022) group standard which will be implemented from the same day. It's the 1st technical standard in China for blast furnace oxygen-rich ironmaking in the iron & steel industry using oxygen supply by VPSA techno...

Due to the fact that both the US and Europe likely heading into recessions, India has emerged as a savior for flagging global steel demand. Poised to overtake China as the world’s most populous country next year, India is in the midst of a building boom. Prime Minister Narendra Modi is seeking to modernize roads, rail networks and ports. That’s set to translate into a 6.7% jump in s...

Since 1985, China, as a major cement manufacturing country, has ranked first in the world in cement production for 37 consecutive years. The cement industry has also become one of the key sectors to be transformed for energy saving and emission reduction due to its high energy consumption attributes. In the cement manufacturing process, cement kilns as the core coal-fired calcining equipment a...

On December 8, 2022, the Standardization Committee of the China International Association for Promotion of Science and Technology (CIAPST) issued an announcement that the group standard for Technical Requirements for Hydrogen Purification System by Medium-Temperature Pressure Swing Adsorption Technology which was drafted with the participation of PKU Pioneer was offi...

1. Increasing flame temperature: High oxygen purity can effectively increase the theoretical combustion temperature of pulverized coal particles. Simulation results and actual measurements have proved that oxygen-enriched combustion of pulverized coal in cement kilns can significantly increase the flame temperature and overall temperature. 2. Accelerating the combustion rate: Oxygen enrichmen...

The VPSA oxygen system mainly includes blowers, vacuum pumps, switching valves, adsorbers and oxygen buffer tanks. (1) Blower: The blower is equipped with a pipe at the entrance to collect the air and continuously provide a certain pressure to create conditions for oxygen production. The blower provides air for the whole oxygen system. According to the design conditions of the VPSA ox...

Recently, the first high-grade nickel matte production line of a smelter in Indonesia was officially put into operation. After drying in the drying kiln, roasting in the rotary kiln and smelting in the oxygen-enriched side-blown furnace, high-grade nickel was successfully produced. This marks the world's first successful industrial application of oxygen-enriched side-blown furnace (OESBF)...

In the past 20 years, China's economy has been developing steadily and rapidly. The continuous upgrading and innovation of production processes of iron and steel, non-ferrous metallurgy, chemical industry, furnace, environmental protection and other industries boosted the demand for oxygen, thus promoting the development of oxygen production technologies such as cryogenic air separation process...
