           Table  2.16   Calculation  Procedure  for  Depreciable  Capital  Cost—
           Individual Factor Method___________________________

           1. Obtain purchased equipment costs for carbon steel at the tabulated size
           and also the capacity exponent from Table 2.9.

           2. Calculate the equipment cost at the required size from  Equation 2.15.1
           in Table 2.15.

           3. Obtain cost indexes from Table 2.12.
           4.  Calculate  the  equipment  base  cost,  C PB2i,  at  the  present  time  from
           Equation 2.15.2.

           5. Calculate the equipment cost, C PAi, at the design pressure and tempera-
           ture,  material  of  construction,  and  the  required  equipment  design  from
           Equation  2.15.3.
           6.  Obtain  the  direct-cost  factors  for  each  piece-of-equipment  from  Table
           2.8.

           7. Calculate the equipment installation factor, f, from Equation 2.15.4.
                                                   M
           8. Repeat steps 1 to 7 for all major equipment.

           9. Calculate the  installed equipment cost at actual process conditions, C Ai,
           from Equation 2.15.5.

           10.  Calculate  the  installed  equipment  cost  at  the  base  conditions,  C Bi,
           from Equation 2.15.6.

           11.  Obtain  f AB,  the  combined  factors  for  buildings  and  auxiliaries,  from
           Equation 2.15.8.

           12. Calculate  the depreciable capital cost from Equation 2.15.7.
