This invention provides cost-effective alternatives to reduce the cost associated with customary blowdown from steam generating equipment. By selectively recycling process blowdown streams using secondary vaporizers, the net result is a partial replacement of wastewater stream with almost an equivalent quantity of clean steam condensate. The heat transfer is carried out by indirect contact devices, such as shell and tube heat exchanger and the like, without mixing of the two process streams to allow condensate recovery while avoiding cross contamination. This invention carries economic as well as environmental credits. A condensate recovery apparatus can be designed to enable easy connection to existing equipment already in service, as well as easy removal, without causing process disruption.
