Recently, PKU Pioneer successfully held its 2024 Annual Summary Conference. Over the past year, the company achieved a total revenue of 629 million RMB (approximately 87 million USD) and made significant progress in global markets. Its VPSA (Vacuum Pressure Swing Adsorption) oxygen generation plants were once again successfully exported to Malaysia, while exports to Indonesia and India continued to see leading growth, providing strong support for the sustainable development of the steel, nonferrous metallurgy, and chemical industries. In addition, the PSA hydrogen purification solution was successfully delivered to Russia, further strengthening the company's presence in the hydrogen separation area. The PSA-CO purification plant was also exported to the United States for the first time, demonstrating PKU Pioneer’s competitive strength in high-end markets.
Through continuous innovation and optimization, PKU Pioneer's VPSA oxygen units have been successfully applied in over 400 industrial projects across the globe, earning widespread recognition from clients. In those cases, users have spoken highly of both the outstanding performance and the intelligent operation and maintenance (O&M) services of the oxygen equipment, highlighting them as key factors for improving production efficiency and reducing operating costs.
PKU Pioneer’s smart O&M services not only significantly enhance oxygen system operation efficiency but also empower users in managing their production processes with greater precision and efficiency through functions such as data analytics, fault diagnosis, and automated adjustment to help ensure stable operation, extend equipment service life, and reduce maintenance costs.
Leveraging advanced automation control technology and a data-driven service model, PKU Pioneer’s VPSA oxygen generation plant operation and maintenance (O&M) is centered on intelligence and efficiency to ensure long-term stable operation while continuously reducing costs and improving benefits. It was concluded at the annual conference that the distinctive features of the O&M system are reflected in the following key aspects:
1. Twofold Benefits: Intelligent Monitoring & Remote O&M
PKU Pioneer’s self-developed "Pioneer Cloud System" utilizes online sensors and smart data acquisition devices to analyze critical parameters (e.g., purity, pressure, temperature, vibration) in real time. By combining IoT technology with a back-end expert system, remote diagnostics are enabled. Users can check the VPSA oxygen equipment status via a mobile or desktop client, while technicians access shared data to swiftly identify faults and provide solutions. For example, if valve or blower malfunctions occur, the VPSA oxygen system automatically triggers alarms and delivers troubleshooting recommendations, minimizing unplanned downtime.
2. Outstanding Auto-Regulation and Self-Healing Capability
Adaptive to Environmental Changes: To address oxygen production fluctuations caused by significant day-night temperature variations, the PLC program automatically adjusts sequencing steps and valve parameters to minimize product oxygen gas fluctuations and enhance the stability of the VPSA oxygen unit.
3. Efficient Preventive Maintenance and Full Lifecycle Management
Key Equipment Condition Assessment: Power equipment such as the blower and vacuum pump employs vibration monitoring and performance degradation analysis to predict wear cycles and analyze potential failures, enabling tailored maintenance planning.
Long-Term Adsorbent Maintenance: The PU-8 lithium-based molecular sieve has a lifespan of over 10 years. The VPSA oxygen system optimizes vacuum desorption and controls temperature and humidity to reduce adsorbent degradation risk, lowering O&M costs by 15%-30% compared to traditional solutions while ensuring long-term stable oxygen production.
4. Provide Customized Energy Efficiency Optimization Services
The VPSA-O2 plant dynamically adjusts its operating mode based on the user’s load demands, allowing flexible turndown ratio regulation within a 25%-100% range. For example, in iron & steelmaking and scrap metal smelting industries, where oxygen demand differs between peak and off-peak periods, a series of automated programs help reduce power consumption, effectively lowering energy losses caused by oxygen venting. PKU Pioneer team regularly provides energy consumption assessment reports and continuously optimizes oxygen-generating unit parameters to achieve the lowest operating costs.
5. Effective Emergency Response and On-Site Support
PKU Pioneer has established a 24/7 response network to offer tiered service support:
Remote Guidance: Over 60% of routine issues can be efficiently resolved through video conferencing. During the COVID pandemic, PKU Pioneer successfully completed remote commissioning and after-sales service for multiple projects in Southeast Asia and South America.
Rapid Spare Parts Supply: Key components (e.g., pneumatic actuators, electrical components for key valves) feature modular designs, enabling standard part replacement within ≤2 hours. And the spare parts inventory ensures a 95% availability rate.
Localized Maintenance Training: Comprehensive technical manuals and customized training programs are provided, covering operational procedures, safety protocols, and routine maintenance essentials, ensuring that user teams develop independent operation and maintenance capabilities.
6. Outstanding Application Case Achievements
87,500 Nm³/h Oxygen Plant Project Achieves Remarkable Results:
By integrating an intelligent control system for energy management, the project enabled unattended operation, saving over $144,928 in annual operation and maintenance labor costs while reducing overall power consumption by 12%.
High-Altitude Oxygen Plant Maintains Exceptional Performance:
The VPSA oxygen unit maintains stable oxygen purity through an intelligent temperature and pressure compensation algorithm at an altitude of 2,800 meters and achieves 3 years of continuous operation without major overhauls.
Leveraging over 20 years of industry expertise and data from 400+ gas separation units, PKU Pioneer has built a comprehensive technical support system covering design, installation, and operation & maintenance to enable users to achieve the intelligent VPSA oxygen plant operation and maintenance goal of high stability, low energy consumption, and minimal intervention.
