Web8.3.4.6 Flash Tank or Glycol-Gas Separator. The flash tank, or glycol-gas separator, is an optional piece of equipment used to recover the off-gas from the glycol-powered pump and the gaseous hydrocarbons from the rich glycol. The recovered gas can be used as fuel to the reboiler and/or stripping gas. Any excess gas is usually discharged ... WebThe maximum heat energy - enthalpy - in the water (condensate) at atmospheric pressure and 100 oC is 419.0 kJ/kg. Evaporation energy of water at the final condition at atmospheric pressure is 2257.9 kJ/kg. The flash steam generated can then be calculated: w = ( (670.9 kJ/kg)- (419.0 kJ/kg)) / (2257.9 kJ/kg) = 0.11 (kg flash steam / kg condensate)
