If allowed to build up

If allowed to build up - ?

The excess aqueous phase must then be drawn off first before hydrocarbon condensate can be removed from the slug catcher, potentially starving the condensate stabiliser from hydrocarbon feed for some time.
The presence of solids causes further problems. If allowed to build up in the slug catcher they can block outlets and can promote under-deposit corrosion.

thanks in advance
