Flash tanks are designed to have an internal velocity slow enough so that the venting steam will not pick up any water. To accomplish this a large diameter tank is required. The model of Flash Separator uses a smaller diameter tank and a tangential inlet that spins the condensate around creating a low pressure area in the center of the separator. This allows the condensate to flash into the center and follow it upwards to the centrally located vent providing clean dry steam. The smaller size and clean dry steam are the reason why current model of Flash Separator is replacing traditional flash tanks. user has to assign only the following parameters:
1-High pressure, bar.
2-Low pressure, bar.
3-Steam flow rate, kg/s.
The model will calculate the following:
1-All design aspects (Flash tank diameter, height, Drain, vent, etc).
5-Total mass flow rate, kg/s.
6-Bottom tank flow rate, kg/s.
7-Cost analysis, $/y, $, and $/hr.
