Hi,
I am currently working on relief system for an existing Condensate Recovery system.
MP Condensate is flashed, LP steam is recovered and the condensate is sent to the condensate recovery system
During blocked liquid outlet for the condensate flash drum, there will be liquid overfill and since the operating pressure of the MP steam is higher than the design pressure of the flash drum, it will lead to over pressurization.
The RV is adequately sized, but there will be relief to the atmosphere. The relief will be two phase, but at the moment the relief is to atmosphere like we have for vapour relief. There would be hot water sprayed from the outlet piping of the RV in the current set-up.
The issue is that, based on my past experience, I have never seen RV on a condensate flash drum where-in hot liquid condensate relief is routed to safe location most of them are similar to vapour relief. I assume that in all the condensate system there would be liquid overfill scenario.
Am I missing something, or my view is correct.
Revert in case of any query.
Regards,
