At what temperatures in industry can materials be cooled using ordinary cooling water?
Thread Content
As the title suggests, in industrial distillation towers, at what temperature above zero degrees Celsius can cooling water be used as the cooling medium for the condenser? At what temperature above Celsius can cooling water be used for heat exchange in logistics? Thank you all for your guidance~
Theoretically, as long as there is a temperature difference, it can be cooled using cooling water. If the temperature difference between the material and the cooling water is small, the heat exchange area of the heat exchanger must be designed to be large; therefore, it is also necessary to consider whether this approach is economically viable.
Generally, when the temperature difference between hot and cold is greater than 25°C, the calculated heat exchange area is considered economically sound.
If the temperature difference is too large, staged cooling is a better option. It allows heat to be recovered while also extending the lifespan of the equipment.
