If the air temperature in the small air separation unit expander is lower than the liquefaction temperature corresponding to the local pressure, part of the gas will liquefy and droplets will appear in the expander. However, the rotating speed of the working wheel of the turbo expander is very high, and the droplet impact on the impeller will cause the impeller surface wear. The droplets may also be thrown to the gap between impeller edge and deflector under the action of centrifugal force. When the temperature of the droplet increases, it will gasify rapidly, and the volume will expand suddenly. If it is serious, it may damage the pressure gauge or fracture the impeller.
The remote intelligent monitoring system developed by DEAR Air Separation makes the unit field and remote monitoring terminal realize the whole process intelligent management. The early warning of fault detection and the cost of field operators are saved.
