AP-89 Vent Steam Recovery ©PSX2010 AP-89 1/09 20101210 Application: Waste & Vent Steam Condensation It is often desirable to utilize vent or waste steam rather than simply release it to the atmosphere or condense it into water to eliminate the steam. The difficulty has been finding a way to safely and stably condense the steam into a process fluid so the energy can be used in a productive manner. Vent steam is often variable in pressure and availability. Traditional heat exchangers often have trouble functioning in this manner making them problematic. Some issues associated with heat exchangers: ! Sizing the exchangers to handle the liquid and steam flow results in the heat exchangers overly large, adding expense and pressure drop to the system ! Sizing
