According to the system water balance, water treatment to ensure that the circulating water system does not corrode and scale.

Water treatment operation steps: flushing the system with clean water is to remove mechanical impurities and suspended matter from the system. When the water system is full of water, then turn on the pump to run. When the turbidity of the circulating cooling water system is high, drainage replacement is carried out. When the turbidity is below 20mg, then move on to the next step.

Cleaning the pre-film in small air separation units: when putting medicine in the cooling tower it is forbidden to remove the water from the cooling tower. Drain again after 24 hours of continuous operation and refill with fresh water. The purpose of this step is to remove oil from the system and to purify the metal surfaces of the water cooling tower of the air separation plant. The next cleaning stage prohibits the drainage of water, which is then drained after 72 hours of continuous operation and replenished with clean water. The purpose of this step is to form a protective film on the metal surface to prevent corrosion of the metal.

The unattended system developed by Dear Air Separation allows operation and maintenance personnel to monitor and record data on site small air separation units from thousands of miles away and to optimise in real time for more accurate and rapid regulation of small air separation units and large air separation units as well as liquid air separation plants.

Generally, the actual cooling capacity of expander is always less than the theoretical cooling capacity. Under the same inlet and outlet pressure and inlet gas temperature, the lower the efficiency of expander, the smaller the unit refrigerant cooling capacity and the smaller the temperature drop efficiency of expander. The efficiency of expander depends on the size of various losses inside the expander. Due to the existence of various losses, the ability of gas to do external work is reduced in varying degrees. To sum up, the losses mainly include the following aspects: 1. When the air flow passes through the work wheel and the deflector, the loss caused by friction and air flow impact on the runner surface is called flow loss. 2. When the impeller is rotating, the friction heat generated by the gas around the wheel disc will increase the temperature of the gas, which is called friction blast loss. 3. When the gas passes through the deflector, the leakage from the gap bet
