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. 

This section is provided on the CD-ROM that accompanies this book. It shows how to use purchase and installation cost estimates from Aspen IPE and other sources, together with an economics spreadsheet by Holger Nickisch (2003) to estimate profitability measures for the monochlorobenzene separation process, which was introduced in Section 4.4. In Section 16.7, Aspen IPE was used to estimate the total permanent investment for this process. The economics spreadsheet, Profitability Analysis — l.O.xls, is on the CD-ROM that accompanies this book. 

Figiue 21.34 shows the monochlorobenzene separation process introduced in Section 4.4. The process involves a flash vessel, V-100, an absorption column, T-lOO, a distillation column, T-101, a reflux drum, V-101, and three utility heat exchangers. As shown in Figure 4.23, most of HCl is removed at high purity (96 mol% by design) in the vapor effluent of T-100. However, rather than use the treater to remove the residual HCl, it is removed in the small vapor purge from T-101. The benzene by-product and monochlorobenzene product are obtained at high purity as distillate (99 mol% benzene) and... 

In this section, the use of Aspen IPE for equipment sizing and costing is illustrated for a depropanizer and for the monochlorobenzene separation process.

Consider the cooler, H2, in the monochlorobenzene separation process in Figure 4.23 and 4.24. Assume that the heat is transferred to an infinite reservoir of cooling water at 77 °F.
