GlobalSpec now has easier access to presentation archives from their Virtual tradeshows. Here is the presentation Kevin Preising gave at the "Industrial Processing" event in August of 2010 entitled "Reuse the energy - don't lose it!"
Why should I view the presentation?
With fuel comprising 60-70% of the operating costs of a typical steam plant, dumping high BTU steam condensate down the drain costs you money. Treating and reusing condensate with a condensate polishing system pays for itself in 12-18 months. This presentation will detail the economics of sodium cycle condensate polishers.
FYI, you may have to register with Globalspec, but it is easy and free to do so.
