Although based on different methods and developed in different platforms, all five programs are user friendly and are useful tools for estimating the capital cost of chemical process plants.
Since material, pressure and installation factors vary in different methods in calculating total module cost, capital cost estimates may differ. Unless otherwise indicated, rates apply for a primary residence in VA, NC, SC, MD, GA or DC and assume escrow of property taxes, homeowner’s insurance, and, if required, flood insurance. Rates shown are for a 30-day lock period. For fixed-head heat exchangers and pumps, there is greater deviation in both purchase and total module costs among different programs studied. All rates are subject to change without notice. AspenPEA has the most equipment types available out of the five programs.
Unlike previous studies which used a statistical approach to examine the influence of causal factors on the variation in costs, this report is based on actual case studies at four nuclear power plants operated by two utilities. The cost estimates are compared and analyzed at both the equipment and plant levels to uncover the relative strengths of each of the programs used. This study examines the role of regulation in the escalation of capital additions costs for nuclear power plants over the past ten years. CapCost, EconExpert, AspenTech Process Economic Analyzer (Aspen-PEA), Detailed Factorial Method (DFP) and Capital Cost Estimation Program (CCEP) were evaluated using seven case studies taken from textbooks. The purpose of this appendix is to present the equations and figures that describe the relationships used in the capital equipment-costing program CAPCOST introduced in Chapter 7 and used throughout the text.
