Deck type liquid distributor

Deck style distributors are clamped on anannular ring that is seal welded to the
tower wall. For revamp applications of trayed columns, most often an existing
tray ring is utilized and seal welded segments are added as needed. In the case
where welding is not permitted, bolt-in segments are available by special request
but provide a less reliable liquid seal.Leakage from and around bolt-in support
ring segments can be a significant portionof the total liquid flow, resulting in poor
distribution quality. In this case, a trough Supporting a channel type distributor
on an annular ring generally requires a more complex design and construction in
order to provide drip points at the proper proximity to the tower wall.

This increased complexity can be avoided by supporting channel type
distributor with the center channel resting on a seat and the channel troughs hung from beams or
a ring above. Both beam and ring supported channel distributors can be designed to accommodate
uplift conditions.The center channel of a channel type distributor provides cross flow capacity between
troughs, to enable liquid head equalization.

The addition of covers or hats over the gas riser area provides the ability to turn the device into a redistributor for use
between packed beds. This design is especially useful when tower elevation is tight and minimal height for redistribution
is required
