Abstract
One or more trays for use in distillation columns and methods of manufacture of such trays. 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.
Claims13
A method of manufacturing a tray for use in a distillation column, the method comprising:
- forming a first set of through holes extending between a first surface of a plate and a second surface of the plate, the second surface opposite to the first surface, the first set of through holes each having substantially a first diameter;
- forming a second set of through holes extending between the first surface and the second surface, the second set of through holes each having substantially a second diameter that is different than the first diameter;
- and
- attaching a weir to the first surface between the first set of through holes and the second set of through holes,
- wherein the first diameter of the first set of through holes is such that the first set of through holes are capable of allowing liquid to pass through the first set of through holes in a first direction while at the same time allowing vapor to pass through the first set of through holes in a second direction that is opposite of the first direction, and the second diameter of the second set of through holes is such that the second set of through holes are capable of allowing liquid to pass through the second set of through holes in the first direction while substantially blocking vapor from passing through the second set of through holes in the second direction.
