When performing a cost analysis on a chemical process, usual considerations include the total installed cost of the plant and the annual operating costs.  Many various costs are included in these two cost divisions.

Corrosion is costly!  If you doubt this, then you probably have never been bitten by the "corrosion bug".  Imagine specifying Titanium for 10 brand new heat exchangers or reactors and later realizing that the processing stream has fairly high concentrations of flourine ions.

As you chemical engineers toss and turn, the words 'liability,' 'risk,' 'preventible accident,' 'catastrophic event' are running through your head. You don't need to count sheep -- you need to get up in the morning and arrange for viable, technically focused documentation and training for your chemical equipment and lines.
