The Challenge
Designing a new BPA Process Is it energy efficient? What operating costs can I expect? How can I reduce drying energy cost?

Activated Economic Analysis
This is the new Activated Analysis panel in Aspen
Plus v8.2. It enables quick relative cost analysisand energy analysis.
Under the hood, Aspen Plus uses AspenTechsproven cost modeling technology to rigorouslyevaluate capital and operating costs.
The cost estimates can be handed overelectronically to an estimator to do a more detailedanalysis using Aspen Capital Cost Estimator.

Operating Cost Estimates
The Process Utility feature in Aspen Plus lets you specify the cost of each type ofutility (steam, hot oil, etc.). You assign the utilities to the operations that requireheating and cooling. Aspen Plus calculates the new utility cost and the carbonequivalents (greenhouse gas).

Energy Analysis Recommendation
C303 C302
Energy analyzer suggests adding an exchanger upstream of C303
condenser and upstream of C302 reboiler.This could make the process hard to control, however.Instead, we can use C303 condenser to generate steam which can beused in the C302 reboiler
