When a Louisiana chemical plant suffered a site-wide blackout, plant personnel learned they would have to bring each power-generation unit, and its corresponding water filtration system, back on-line individually. Facility workers quickly returned the onsite demineralization system to functional status, but it was receiving almost zero condensate return.
To re-establish condensate return, which is a liquid procured from steam to increase energy-production efficiency, the plant would need to increase its flow rate by approximately 1,800 more gal per minute (gpm) than its system could produce.
