Design of Cooling Water Networks

In other words, if the mixing junction is moved from the middle of the operation to the beginning of the operation, there is a constant flowrate throughout the operation corresponding with the maximum inlet temperature, after mixing. 

Parallel cooling water use that is minimized to achieve A Tmin at the outlet of each heat exchanger leads to a flowrate for the network of 25.4 kg s-1, with a cooling water return temperature of 52°C. Maximizing the reuse reduces this flowrate to 21.5 kg s-1, and the cooling water return temperature increases to 57.8°C. 

A number of complications need to be addressed that are likely to be encountered. 

The shifted limiting cooling water data are given in Table 24.2. 

The next stage is to find the target supply conditions for the cooling tower. This can be achieved by constructing a simulation model of the cooling tower to simulate the conditions of the exit water and air for given inlet air and water conditions2. The model must also consider the
