Cost estimation using ASPEN ICARUS

EQUIPMENT SIZING AND CAPITAL COST ESTIMATION USING THE ASPEN ICARUS PROCESS EVALUATOR (IPE)... 

Be prepared to use the Aspen Icarus Process Evaluator (IPE) system provided by Aspen Technology, Inc. to prepare a more definitive estimate of capital cost. 

Part Three includes chapters that provide instruction and examples of the design of heat exchangers, multistage and packed towers, and pumps, compressors, and expanders. In addition, Chapter 16 provides guidelines for selecting processing equipment and equations for estimating the purchase costs of a broad array of equipment items. Furthermore, Section 16.7 shows how to use the Aspen Icarus Process Evaluator (IPE), with the process simulators, to estimate purchase costs and the total permanent investment for a chemical plant. 

W The feed to a sieve-tray distillation column operating at 1 atm is 700 Ibmol/hr of 45 mol% benzene and 55 mol% toluene at 1 atm and its bubble-point temperature of 201°F. The distillate contains 92 mol% benzene and boils at 179°F. The bottoms product contains 95 mol% toluene and boUs at 227T. The column has 23 trays spaced 18 in. apart, and its reflux ratio is 1.25. Column pressure drop is neglected. Tray efficiency is 80%. Estimate the total bare-module cost of the column, condenser, reflux accumulator, combined reflux and distillate pump, reboiler, and reboiler pump. Also, estimate the total permanent investment Results should be computed using (1) the equations in Chapter 16, and (2) Aspen IPE (Icarus Process Evaluator). Compare the results.
