Flash Separators are sized for the condensate flow entering the tank and the amount of flash steam that is produced when venting to a lower pressure. To select a flash separator use Chart "A" to determine the flash steam amount and Chart "B" that gives the size of tank and nozzle connections sizes required.

CHART "A" - PERCENTAGE FLASH STEAM

To use Chart A follow the "PRESSURE FROM" (horizontal at the top) down vertically to the "FLASH TO" pressure. All pressures are in psig.
