Monochlorobenzene separation process. This process was introduced in Section 4.4, with simulation results using ASPEN PLUS provided on the CD-ROM (ASPEN PLUS — Principles of Flowsheet Simulation Interpretation of Input and Output —> Sample Problem). Beginning with the file, MCB.bkp, the equipment sizes, purchase costs, and installation costs are estimated using Aspen IPE. 

Additional features of Aspen IPE are introduced for a more complete process, the monochlorobenzene (MCB) separation process, which is discussed in Sections 4.4 of the textbook (Seider et al., 2004). A copy of the simulation file, MCB.bkp, is provided on the CD-ROM that contains these notes. 

In this section, equipment sizes and costs are estimated for the monochlorobenzene (MCB) separation process, which is discussed in Section 4.4 of the textbook and in the multimedia portion of the CD-ROM (ASPEN Principles of Flowsheet Simulation Interpretation of Input and Output —> Sample Problem) that contains these course notes. Beginning with the file, MCB.bkp, which is available on the CD-ROM, additional mixture properties are added and the DISTL subroutine, used to model the D1 distillation column, is replaced with the RADFRAC subroutine. The reflux ratio computed using the RADFRAC subroutine is 3.35, as compared with 4.29 computed using the approximate DISTL subroutine. Also, the stream flow rates differ slightly (< 1%). Both of the files, MCB-IPE.bkp and MCB-IPE.rep, are on the CD-ROM. 

After the simulation file is augmented, the revised simulation is run and the results are sent to Aspen IPE. Note that the ASPEN PLUS and HYSYS.Plant simulators contain menu entries to direct the results to Aspen IPE. For details, the reader is referred to course notes prepared at the University of Pennsylvania (Nathanson and Seider, 2003), which are provided in the file. Aspen IPE Course Notes.pdf, on this CD-ROM. This section presents estimates of equipment sizes and purchase and installation costs using Aspen IPE for two examples involving (1) the depropanizer distillation tower presented on the CD-ROM (either HYSYS —> Separations —> Distillation or ASPEN PLUS Separations Distillation), and (2) the monochlorobenzene (MCB) separation process introduced in Section 4.4, with simulation results using ASPEN PLUS provided on the CD-ROM (ASPEN Principles of Flowsheet Simulation —> Interpretation of Input and Output —> Sample Problem). Just the key specifications and results are presented here. The details of using Aspen IPE for these two examples are presented in the file. Aspen IPE Course Notes.pdf... 

It is desired to carry out a profitability analysis for the monochlorobenzene (MCB) separation process using (a) purchase costs and bare module factors, (b) purchase and installation costs estimated by Aspen IPE. In Section 16.7, the latter estimates were computed, beginning with the ASPEN PLUS simulation in the file, MCB.bkp. Plant location is the Gulf Coast. The design time is estimated to be one year, the construction time at one year, and the total operating life of the project at 15 years. Assume that 5% of the total permanent investment is...
