DESIGN OF AN ETHANOL PURIFICATION SYSTEM
Your team has been contracted by a small chemical company located in northern Indiana to design a system to remove 98% of a contaminant ethyl acetate from a process stream. The process stream flow rate is 35 m3/hr and contains 4.5% ethyl acetate. It has been suggested that a vacuum sieve-tray column operating at 0.65 bar would be an economical choice.
In order to evaluate the viability of the proposed system, equilibrium data for the ethanol/ethyl acetate system and sieve tray efficiency data are required.

Other strategies to try:ethanol and “ethyl acetate” and “equilibrium data” 26 results
ethanol and “ethyl acetate” and “phase-equilibria” 45 resultsethanol and “ethyl acetate” and “phase-equilibri*” 56 results
ethanol and “ethyl acetate” and “equilibrium stud*” 1 result
ethanol and “ethyl acetate” and equilibrium 210 results
And more: VLE, vapor-liquid, “ethyl ethanoate”, EtOAC, etc.

Search Strategy - SciFinderResearch topic search “reaction kinetics of o-
xylene to phthalic anhydride”
Take 17 hits and limit to additional topic of “plug.”View that first Calderbank article; some data available.
Go back and limit original 17 by “maleic.”One readable article in English; view. Note discrepancy,
follow to additional article from bibliography.
Go back and limit original 17 by review articles only.One in English; view for tables that compile data for
various catalysts.
When there is no easy solution…Read the article/research
Follow additional leadsAuthors, citations, etc.
Confirm findings if necessary/possible
Modify your projectMethod, catalyst, etc.
Determine yourself by experiment

SummaryUse print and online resources
Consider compiled data in handbooks AND experimental data reported in research (journals, patents, etc.)
Look for possible next steps when stuck
[When things get difficult,] take notes of what you have already done, especially for sharing with your team
