How to set the ASPEN shell-side and tube-side property methods separately, as shown in the figure

If the hot fluid is oil, then the cold fluid is an ethylene glycol solution. For oil, GRAYSON can be chosen, but under the PROPERTY interface only one property calculation method can be selected. So how do I choose the property calculation method for ethylene glycol?
In ASPEN, when dealing with multiple groups of fluids, different property methods can be selected for each fluid separately. To set the properties of the ethylene glycol solution separately, you can follow these steps: 1. In the Flowsheet window, select the unit or stream to which the ethylene glycol solution belongs. 2. Right-click and select “Fluid Package” from the pop-up menu, then choose “Property Method”. In the open dialog box, you can choose which property method to use. If the GRAYSON method was previously chosen as the property calculation method for oil, you can now select a method suitable for ethylene glycol solutions, such as NRTL or UNIQUAC. After completing the settings, confirm and save them. This approach ensures that during the processing, oil and ethylene glycol solutions are calculated using their respective property methods, thereby enabling accurate simulation and analysis of the characteristics of the fluids on both sides. .

I don’t see a Fluid Package option when I right-click? How did you get it adjusted?
Add a centrifugal pump; no gas should be present at the inlet of this pump. Therefore, a reservoir or water storage tank should be installed at the source of the water supply. A level switch can be used to ensure that the pump starts automatically when the water level reaches a certain threshold. The initial investment is higher, but the pump does not need to run continuously, which results in energy savings
