Does the amount of coolant in a packed tower have a significant impact on the product quality of the tower?
Thread Content
Our facility has two separation units, and the temperature of the circulating water is adjusted to stay between 20 and 30 degrees (controlled by cooling fans). Sometimes, fluctuations occur in the content of light components at the top of the towers in these two units. Is this related to the amount of cooling agent used? There are no significant changes in utilities such as MS; the CW temperature is controlled between 20 and 30 degrees using cooling fans.
The direct cause lies in whether the size of the refrigerant leads to changes in the top temperature of the tower; once the top temperature changes, the composition will naturally fluctuate.
There is definitely an impact; the amount of cooling directly affects the evaporation rate in the tower as well as the composition of the light components. Excessive cooling also increases energy consumption.
Of course it is large. It can be said that the temperature at the top of the tower is largely maintained by the refrigerant; an excess amount of refrigerant supplied to the top of the tower will change the operating conditions of the tower, thereby affecting the composition and pressure of the material exiting from the top of the tower
