The air temperature at the outlet of the air separation air-cooling tower is on the high side
Thread Content
The designed outlet temperature of the air-cooled tower is 14.5°C, but in actual operation it reaches 16–17°C; meanwhile, the temperature of the cooling water is also above 11°C, which is far from the designed range of 6–9°C.
Is the requirement for air cooling that low? Can the cooling water temperature be achieved? Our company can’t go that low
Check the design of the chiller and its previous operation records to see if maintenance is required. Additionally, try reducing the flow rate of the chilled water to see if there is a tendency for the temperature difference between the exit of the air-cooled tower and the temperature of the chilled water to decrease~~
Hehe, hurry up and think of a solution; it’ll be time to lie down soon. If the carbon dioxide level rises, it will be troublesome. Taking the temperature of the air exiting the air-cooled tower as a reference, the water temperature serves to support it.
For this issue, given our operating conditions, one approach is to check the problems with the chiller – for example, whether there is a lack of Freon in it, whether its settings need to be adjusted, as well as issues related to the main board and current levels. Another solution is to inject more nitrogen into the water cooling tower. Additionally, it’s necessary to reduce the temperature of the circulating water at the source. Finally, check whether the packing in the air cooling tower has formed clumps, which might prevent proper heat exchange between water and air. I hope this can help you.
This is the outlet temperature of our air-cooled tower; the desired outlet temperature range is 8–12 degrees
What’s the process like? Is a water-cooled tower or a chiller being used? It is recommended to first check the condition of these two devices and lower the temperature of the cooling water to the designed range of 6–9°C ； Additionally, the amount of water used for freezing should be appropriate; too much or too little is not good.
The chilled water flow rate has also been adjusted, but the impact is not significant. The chiller is not currently in use, and the temperature of the chilled water is on the high side; we are now preparing to start the chiller unit.
I would like to know what is the capacity of your air separation unit, how much cooling water is used, and what are the temperature levels? ?
What is the outlet air temperature of your company’s air-cooled tower? What is the cooling water temperature? Which method is used for cooling?
Yes, that’s exactly what worries me. Could I take a look at the pictures from your company?
