Short Description:

Helium is a rare and non-renewable gas resource with limited global reserves and growing demand, leading to rising prices. The helium recovery and purification system is designed to efficiently recover and purify helium containing impurities, enhancing helium utilization efficiency. This system removes impurities such as water, carbon dioxide, nitrogen, and oxygen from helium, providing high-purity helium. It helps customers reduce costs and create significant economic value.

Overview:

Helium is a rare and non-renewable gas resource with limited global reserves and growing demand, leading to rising prices. The helium recovery and purification system is designed to efficiently recover and purify helium containing impurities, enhancing helium utilization efficiency. This system removes impurities such as water, carbon dioxide, nitrogen, and oxygen from helium, providing high-purity helium. It helps customers reduce costs and create significant economic value.

Working Principle:

Impure helium gas is first compressed using a compressor and then passed through filters to remove oil and water. The gas then enters a dryer to further eliminate moisture, carbon dioxide, and residual oil. Following this, the gas is purified using pressure swing adsorption (PSA) and membrane separation technology to effectively remove nitrogen and oxygen impurities. This system can increase helium purity to over 99%, with a recovery rate of over 95%, enabling efficient reuse of waste helium. The purified high-purity helium can be used to fill cylinders or applied directly.

Technical Parameters:

• Helium Processing Capacity: 3 Nm³/h to 1000 Nm³/h
• Operating Pressure: 0 – 15 MPa
• Feed Helium Purity: 10% – 90%
• Purified Helium Purity: 95% – 99.9%
• Helium Recovery Rate: 80% – 99%

Technical Features:

• Filtration System: Filters are installed before the purification unit to ensure the initial removal of oil and water.
• Flow Monitoring: A flow meter is installed at the outlet of the purification unit to monitor processing capacity in real-time.
• Secondary Purification: A bypass valve and loop pipeline are configured at the purification unit outlet for secondary purification if the gas purity does not meet the required standard.
• Rapid Purification: The purifier can quickly produce standard-compliant helium gas within 5 minutes, with fully automated operation.
• Control System: Equipped with a programmable logic controller (PLC) for automated system control, with sensors at critical points to support remote monitoring and operation.
• Testing Interface: The system includes a testing interface for helium purity monitoring, ensuring easy and convenient purity checks.

Applications:

This system is widely used in industries such as optical fiber manufacturing, electronics, laser welding, cold spraying, military applications, helium balloons and airships, MRI equipment, chemical processing, leak detection, medical devices, and air conditioning systems.
