Definitions
- Liquid receiving area is defined as the area ust below the liquid discharge openings of the consecutive tray above in a column provided with a plurality of axially spaced trays according to the invention.
- the flow path is the horizontal part of the liquid flow path on a tray, wherein the liquid is intimately contacted with the upwardly moving gas .
- the cross-sectional area at the lower end of the downcomer is defined as the area between the two lower ends of the elongated walls of the rectangular downcomer.
- the cross-sectional area of the downcomer at tray level is defined as the area between the two elongated walls of the rectangular downcomer at tray level .
- the cross-sectional area at the lower end of the downcomer is more than 5% and more preferably more than 10% of the cross-sectional area of the upper end of the downcomer at tray level.
- the cross-sectional area at the lower end of the downcomer is less than 30% of the cross- sectional area of the upper end of the downcomer at tray level .
- a rectangular downcomer is defined as a downcomer with a downcomer opening at tray level having two elongated sides and two smaller end sides.
- a rectangular downcomer for this invention also includes a downcomer having a downcomer opening wherein the smaller end side nearest to the circumferential of the tray runs along this circumferential, resulting that these smaller end sides are not parallel arranged relative to each other.
- This design of the downcomer opening ensures a maximum opening area on the tray.
- a downcomer opening is used having parallel smaller end sides.
- the downcomer is preferably provided with a rectangular shaped anti-jump baffle, vertically positioned along the longitudinal centre in the opening of the downcomer.
- This anti-jump baffle plate is suitably supported from both sides by supports which are fixed to the inside of the downcomer walls.
- the tray according to the invention is preferably used m a gas-liquid contacting or separation column, which column is provided with these trays, axially spaced away from each other.
- Contacting can be absorption processes wherein a downwardly moving liquid is contacted with a upwardly moving gas.
- Separation is typically a distillation process to separate one or more components from a feed.
- the feed of a distillation process is supplied to an intermediate position m the column, wherein trays are present above and below said inlet position.
- Such a column is further provided with reboiler, condensation and reflux means.
