Since HX-Net does not have the required unit, the MW unit will be created using the User Conversion. 6. Click on the Unit cell for Energy, then click the Add button.

A network will be created based on a process flow diagram proposed by a contractor.

The concepts introduced here are used throughout the tutorial: creating process and utility streams, adding heat exchangers, and using the worksheet to manipulate the network.

Crude oil is often fractionated to produce saleable products such as heavy and light naphtha, kerosene, gas, and fuel oils.

Linnhoff, D.W. Townsend, et al1 and appears in Figure 1.1.

The crude oil is split and heated in two heat exchangers, 10 and 6, by the Fuel Oil and Light Naphtha product streams, respectively.

The crude feed is then mixed back together and passed through the desalter unit.

Effluent leaving the desalter is heated up further in heat exchangers 9, 7, 8, 5, and 4 by the product streams Heavy Naphtha, Kerosene, Reflux, Gas Oil, and Fuel Oil, respectively.

An air cooler, coolers using cooling water, and boiler feed water heaters are used to further cool the product streams down to their target temperatures.

After the crude oil has been heated by the products, it is passed through a Pre-Flash operation to remove the Light naphtha cut.

The heavier components from the Pre-Flash operation are heated by the hottest portion of the fuel oil in heat exchanger 3, and then passed through two furnaces.

The crude tower takes the heated feed, and separates the Light Naphtha and the Fuel Oil cuts.

The stripper column also produces three other products: Gas Oil, Heavy Naphtha, and Kerosene.1-2.

This includes all process stream information and utility stream information.

Setting Unit Preferences Before you begin, verify that the units currently selected in the preferences are the ones you want to use.

For this example, the desired unit for energy is MW.

On the Tools menu, click Preferences.

The Session Preferences view appears.

Click on the Variables tab, and select the Units page.

Select EuroSI from the Available Unit Sets list, and click the Clone button.

In the Display Units group, scroll through the table until you find Energy.

There is no MW unit in the Energy unit drop-down list, only kW.

Since HX-Net does not have the required unit, the MW unit will be created using the User Conversion.

Click on the Unit cell for Energy, then click the Add button.
