Document Summary
7. 3 total capital cost (tcc) of a plant. 0. 6 more accurate for a plant than for single piece of equipment. Topology and notation of table 7. 6 will be important. Lang factor gives total module cost for plant"s expansion. Multiply sum of purchased costs of major equipment by lang factor f. Flang = 4. 74 for fluid only, 3. 10 for solid only and 3. 10- 4. 74 for fluid-solid. Larger flang means cost of purchased equipment/ ctm is less. In all cases cost of purchased equipment cpi < 30% of ctm. Best method to estimate the cost of a new plant. Relate all costs to the cost of purchased equipment at base conditions c0p. Bare module costs = sum(direct costs + indirect costs) table 7. 6. F naught bm are calculated for equipment and listed in appendix a. Equations for evaluating direct, indirect, contingency, and fee costs. Overhead cost is dependent on the cost of labor.
