Abstract
This disclosure describes one or more trays for use in distillation columns. The trays include a plate having a plurality of through holes that extend between a first surface of the plate and a second surface of the plate. The plurality of through holes include a first set of through holes each having substantially a first diameter and a second set of through holes each having substantially a second diameter that is different from the first diameter. The trays also include a weir coupled to the plate and extending from the first surface. The weir is positioned between the first set of through holes and the second set of through holes.
Claims17
A tray for use in a distillation column, the tray comprising:
- a plate comprising a first surface and a second surface opposite the first surface, the plate having a plurality of through holes extending between the first surface and the second surface, the plurality of through holes comprising:
- a first set of through holes each having substantially a first diameter;
- and
- a second set of through holes each having substantially a second diameter different from the first diameter;
- and
- a weir coupled to the plate and extending from the first surface, the weir positioned between the first set of through holes and the second set of through holes;
- wherein the first set of through holes and the second set of through holes are configured to enable liquid to flow below the plate without use of downcomers.
A tray for use in a distillation column, the tray comprising:
- a plate comprising a first surface and a second surface opposite the first surface, the plate having a plurality of through holes extending between the first surface and the second surface, the plurality of through holes comprising:
- a first set of through holes each having a first diameter within a first range;
- a second set of through holes each having a second diameter within a second range different from the first range;
- a third set of through holes each having a third diameter within the first range;
- and
- a fourth set of through holes each having a fourth diameter within the second range;
- and
- a plurality of weirs coupled to the plate and extending from the first surface, the plurality of weirs comprising:
- a first weir positioned between the first set of through holes and the second set of through holes;
- a second weir positioned between the second set of through holes and the third set of through holes;
- and
- a third weir positioned between the third set of through holes and the fourth set of through holes.
A system comprising:
- a distillation column comprising:
- a housing defining a chamber;
- and
- a plurality of trays positioned within the chamber, the plurality of trays comprising at least one tray comprising:
- a plate comprising a first surface and a second surface opposite the first surface, the plate having a plurality of through holes extending between the first surface and the second surface, the plurality of through holes comprising:
- a first set of through holes each having substantially a first diameter;
- and
- a second set of through holes each having substantially a second diameter different from the first diameter;
- and
- a weir coupled to the plate and extending from the first surface, the weir positioned between the first set of through holes and the second set of through holes;
- wherein the plurality of trays further comprises a second tray that is positioned proximate to the at least one tray within the chamber;
- and
- wherein the at least one tray includes a plurality of weirs extending from the first surface in parallel across the plate in a first orientation;
- and
- wherein the second tray includes a second plurality of weirs extending from a surface of a second plate of the second tray in parallel across the second plate in a second orientation that is different than the first orientation.
