Single Phase Feed Distributors
For a single phase liquid feed to a plate-orifice distributor a sparge pipe is used located centrally between the risers. The pipe can be either a straight type or a Tee-type.
For single-phase liquid feeds to a trough distributor, a feed pipe or a combination of feed pipe + primary trough(s) are required to correctly feed the secondary troughs. Depending on the number of primary troughs the feed pipe can be straight, Tee-type or an H-type.
For single phase vapour feeds a sparge pipe is used (straight, tee or H type) or a pipe ladder distributor. Alternatively a chimney tray can be used to distribute the vapour.
Two Phase Feed Distributors
The importance of correctly feeding a tray or packed column cannot be over-stressed particularly in the case of two phase feeds. Poor design arrangements can lead to premature flooding of the trays or packed bed.
At DtEC we have a wide range of two phase feed distributors thus ensuring the correct type will be selected:
- Sparge Pipe c/w Shroud
- Flashing Gallery
- Vane Inlet Device (VID)
