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 large 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 large air separation units. 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 from thousands of miles away and to optimise in real time for more accurate and rapid regulation of small air separation units，bigair separation units and liquid air separation plants.
