It is often observed while modification of Three phase Seperators due to carryover of water in Hydrocarbon liquid, the weir is extended towards Lighter liquid i.e hydrocarbon side of the vessel but its weir height is reduced post this change. Any logic to reduce weir height please?
Attached the reference drawing for better understanding.
