Inlet Devices play an important role in overall performance of a separation vessel or mass transfer column.
Traditional inexpensive devices that are commonly used at low momentum liquids but negavily affect separation at high momentum are:
A) impact plate
B) dished head
C) half open pipe
D) open pipe at vessel head
However, for higher-momentum streams these inlets can cause problems such as shearing of incoming liquid droplets. more difficult to separate. foaming and liquid short-circuiting or channeling.
