Air separation equipment is used to separate air and produce industrial gases. Its stable operation is of great significance to production, and key points need to be controlled from multiple aspects.
Equipment selection and quality control. It is necessary to select core equipment such as compressors, expanders, and distillation towers reasonably based on the raw air conditions, product purity, and production capacity requirements. For compressors to have high efficiency, low vibration, and good sealing, the accuracy of the impeller and bearings of the expander must also meet the standards. At the same time, low-temperature equipment should use materials that are resistant to low temperatures, and welding and sealing processes should strictly follow standards to ensure the quality of the equipment itself is excellent.
Operational management needs to be refined. Start and stop should be operated according to standard procedures to prevent equipment damage caused by rapid temperature and pressure changes. During operation, closely monitor parameters such as temperature, pressure, and liquid level to ensure they fluctuate within the design range, with a focus on key indicators such as the main cooling liquid level and the outlet temperature of the expander. When adjusting the load, synchronously adjust the refrigeration capacity and distillation tower parameters to maintain system balance.
Develop regular maintenance plans, inspect key equipment, and replace worn parts. Strengthen the maintenance of lubrication and cooling systems, and regularly calibrate instruments and control systems. Implement explosion-proof, fireproof, antifreeze, and moisture-proof measures, and equip emergency plans and fire-fighting equipment.
In addition, operators should receive professional training, familiarize themselves with equipment principles and processes, and pay attention to the quality of raw air to ensure stable power supply and avoid external factors interfering with equipment operation.
