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 enterprise engaged in the comprehensive utilization of non-ferrous metal waste resources, the end-user conducts hazardous waste treatment and recycling with a green and energy-efficient concept and holds an open mind towards practical and advanced high-tech with remarkable energy-saving effects. Compared with cryogenic air separation technology, the VPSA system is based on a new gas separation process, which has outstanding advantages such as faster start-up and shut-down, lower comprehensive energy consumption, more flexible turndown ratio regulation, and less maintenance cost. After a series of in-depth investigations, the customer agreed on the economic efficiency of VPSA technology and highly approved PKU Pioneer’s leading position and technical strength in the VPSA industry during the past nearly 23 years. They eventually chose PKU Pioneer as the VPSA oxygen unit supplier who provided the client with a diversified and economical gas supply solution by including a PSA nitrogen system.

This is the 5th VPSA unit to be built by PKU Pioneer in the region, indicating PKU Pioneer’s significant brand influence and reputation in this major town of non-ferrous smelting and resource recycling. The leading oxygen production solutions provided by PKU Pioneer for hazardous waste treatment enterprises can effectively help the users reduce the comprehensive smelting cost and promote the recycling of resources to achieve the "dual carbon" goal, therefore having far-reaching social implications.

PKU Pioneer has provided nearly 30 sets of VPSA oxygen systems for solid waste treatment, which were used to recycle copper, lead, zinc, gold, silver, antimony and other metals. Our oxygen generators effectively contribute to helping enterprises to improve smelting efficiency and reduce production costs & carbon emissions. With continuous upgrading and innovation, VPSA oxygen generating technology is being more and more widely applied to the solid waste treatment area and has become the recognized and preferred high-quality oxygen production process in the industry.
