I have a question regarding steam condensate flashing
Thread Content
Can the 1.0Mpa steam condensate (at 98 degrees) from our company be flashed into the 0.4Mpa steam network (at 148 degrees)? How is the flash vaporization volume calculated?
98 degrees Celsius? That’s water; it can’t sparkle!
There is a pressure difference; by reducing the pressure from 1.0 Mpa to 0.5/0.6 Mpa, it is possible to feed it into the pipeline network at 0.4 Mpa.

It can be flashed, but it requires a large amount of high-pressure steam; moreover, you need corresponding low-pressure piping as well as a location where it can be used
At 1.0 MPa, the saturation temperature is around 180 degrees; flash vaporization is possible. This is an isenthalpic process, with high-pressure saturated water as the feed and low-pressure saturated water along with saturated steam as the outputs. It’s sufficient for the total enthalpy to be equal.
If the temperature has already dropped to 98 degrees, there’s no need for flashing; if it is to be added to the pipeline network, it can only serve to lower the temperature.
1.0 The saturated temperature of steam is not 180; are you referring to the saturated water at high pressure? Can water be compressed?
I also think it’s not possible; if the temperature is a bit higher, then it might be possible to flash
