 As the non-ferrous metal smelting industry transforms towards "green, low-carbon, high-efficiency, energy-saving, cost-reducing, and efficiency-enhancing" practices, oxygen supply systems, as a core component of pyrometallurgical and hydrometallurgical processes, directly determine production efficiency, environmental compliance, and economic benefits. VPSA (Vacuum Pressure Swing Adsorption) oxygen generation, with its advantages of low energy consumption, rapid start-up, high flexibility, and easy operation and maintenance, has fully penetrated the five major non-ferrous metal smelting scenarios of gold, silver, copper, lead, and zinc, becoming a "key driver" for the industry's quality improvement and upgrading.   Unlike traditional cryogenic air separation which has high energy consumption and slow start-up, and is also superior to purchased liquid oxygen which is expensive and unstable, VPSA oxygen generator operates at room temperature and uses a core prin...

  Atmospheric pressure adsorption + vacuum desorption: the core technology of true industrial VPSA oxygen generation equipment   In the field of industrial oxygen production, PSA and VPSA pressure swing adsorption technologies are often confused, and many users find it difficult to distinguish which VPSA oxygen generator is truly suitable for large-scale industrial scenarios. In fact, industrial-grade VPSA oxygen generators are not simply an improvement on PSA technology, but rather an independent system with fundamentally different core technology routes, hardware configurations, and performance indicators, specifically designed for industrial oxygen needs that require high oxygen production, low energy consumption, and long-term stable operation.   I. Core Technology Route: Low-pressure adsorption + vacuum desorption is the essence of VPSA   The core feature of a true industrial VPSA oxygen generator ​ is that it adopts a pressure path of near-normal pressure adsor...
