300 Area Steam Condensate Recovery Study

摘要

This study investigated the 300 Area Condensate Return Piping System and explored cost effective alternatives to the present operation. The alternative which disposed of the condensate at each building by diverting it to a process sewer had the highest Savings to Investment Ratio (SIR) and shortest payback period. The other acceptable alternative, which replaced the remaining original bellows expansion joints in the condensate return lines, then routed the returned condensate through a water softener to polish the water before returning it to the boilers, had a lower SIR and a longer payback.
