Slug flow in condensate line

[rrrewagad1]

Hello friends!
This is with ref. to condensate recovery system in one of our plant.
I have a query on the percentage of steam (flash steam) allowed in condensate line to avoid corrosion/erosion problems due to slug flow conditions. This flash steam is due to press. drop across control valve.

Present system:
Line size - 2’’
Line length - 475 m
Condensate flow - 6620 kg/hr
Condensate pressure - 2.3 kg/cm2g
Temp. 136 oC

OR what is to be done to avoid the slug flow conditions in such cases...?


Thanks & Regards,
