Flash tanks convert high pressure steam to lower pressure steam and
Usually the condensate temperatures within high
pressure steam are slightly less than the saturation temperature, thus
when it is discharged into a lower pressure area (such as a flash tank)
some of that condensate instantly converts to steam. A flash tank
therefore separates the lower pressure steam from the condensate.
The low pressure steam can be vented though an
atmosphere or used for other processes. Proper sizing of the flash
tank will ensure higher quality (drier) low pressure steam.
flash tanks are designed in accordance with ASME Code Section VIII, Div.
1 and can be ASME Code Stamped for 150 psig steam service;
higher pressure rated vessels can be supplied upon request.
