           We may wish to have streams results summarized with mole fractions or some other basis
        that is not set by default. For this, we can use the Report Options under Setup folder. In the
        subsequent step, select Stream sheet and then choose Mole fraction basis,

                                      ...  -                            rJtW

           As filled out, the form shown in Figure 1.17, final results related to all inlet and
        product streams will be shown additionally in terms of mole fraction. Remember that all
        values in the final results sheet should be given in the British unit as chosen it previously.

        Specifying components
        Clicking on Next button or double-clicking on Components in the column at the left side
        and then selecting Specifications, we get the following opening screen (Figure 1.18).
