Can we just assume the delta Tmin? Or there is calculation for the 25 celcius heat load placement before obtain delta Tmin

You can use any delta Tmin as long as it is greater than zero..in fact, different processing will have different recommended delta Tmin. For example, low temperature/cryogenics will use small deltaT min. In my case i just simply use 10oC

@@sitikhadijah9750 Just want to add...if u decide to choose different deltaTmin..for example 5oC. You just need to shift your hot composite curve such that the 'neck/pinch' is 5oC. Changing delta Tmin will change heat recovery n utility usage...of course if go detail - heat-x area, no of unit etc.

My POV, the recommended value for delta t min is shown in graphs (Cost or Area vs Delta T min) in textbook (PINCH ANALYSIS FOR ENERGY AND CARBON FOOTPRINT REDUCTION) is around 10 to 20. This typically will give maximum efficiency with little to no drawbacks. Hope that helps.
