Dear all,

I would like to know what kind of calculation method is to select the optimal size of steam condensate pipe.
(e.g. delta P/100m, velocity and so on)

WSBAE,

Maximum Allowable pressure drop for condensate line shall be as below.
For 3 barg ---- 0.15 bar/100
For 10 barg ----- 0.2 bar/100m
For 15 barg ----- 0.3 bar/100mm

Regards,

WSBAE,

We use; velocity=1-1.5 m/s

Following link is also helpful in finding the solution for condensate line sizing.

Size the line for velocity of 1-2 f/s, assuming all condensate remained as liquid. Then check whether P1 (pressure at the beginning of line) is adequate for the chosen diameter, calculating two phase flow ΔP across whole line. This is what applied locally, http://www.cheresour...ate-hammering/'> http://www.cheresources.com/invision/topic/12760-condensate-hammering/, post No 5 by kkala.

What about the condensate line sizing before flash drum i.e when condensate is in two phas e not stabilized

whats velocity limitation then kindly provide reference too ...
