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...

In early 2020, the Indonesian government announced the ban on nickel ore exports in order to attract foreign investors to open nickel smelters and downstream industries in its territory, of which China is an important contributor. In 2021, the government continued to implement the relevant injunction to ban the export of processed products with nickel content below 70%. Nickel ore must be pro...

In June 2022, the VPSA oxygen equipment (7250Nm3/h, 90%) established by PKU Pioneer in Hunan Province was put into operation successfully, providing economical and stable oxygen for oxygen-enriched lead slag smelting section in solid waste treatment process to promote efficient recycling of valuable metals and help the user improve its overall economic benefits. As a local well-known...

On July 6th, 2022, the Engineering Department of PKU Pioneer received a Letter of Commendation from a copper smelting customer who fully affirmed the outstanding performance of PKU Pioneer’s technical team in the construction of the VPSA oxygen system project in the letter. Our technical team is highly praised for emphasizing efficiency and surmounting obstacles to ensure the s...

In August 2022, a VPSA oxygen generation equipment (1850Nm3/h, 90%) built by PKU Pioneer for new energy sector was successfully put into operation. Qualified oxygen was generated within 1 hour after the initial start-up with all the indexes meeting the customer's requirements. Upon the delivery of the project, PKU Pioneer's technical team was presented a silk banner with "Superb ...
