Liquid Distributors

TrayHeart can calculate all common liquid distributors. The types of "pan type", "trough type" and "deck type" represent the basic forms. Within these types of construction, the drip points can be defined as bottom hole openings, drip tubes, wall openings and wall slots. The riser openings for the gas flow (round, angular, with / without cover) can also be defined.

Typical designs can be easily created by so-called shortcuts, but special designs can also be defined in great detail.

By linking the liquid distributor and the packed bed in a profile file, the drip points of a defined liquid distributor can also be used as the initial distribution for a bed and thus the distribution quality in relation to this packed bed can be evaluated.

All distributors are shown as interactive 3D graphics. The liquid feed points can be visualized as a cone and the distribution image can be displayed in this way.

Distributor Performance

The distributor performance characteristic indicates the liquid level in the distributor for the entire range of possible load. The operating point, its stability and the operating performance of the distributor can be characterized on the basis of these characteristics.

Distributor Quality acc. to Moore&Rukovena

The quality calculation according to Moore&Rukovena is available for all distributors. With this model, an absolute quality index can be calculated.

Distributor Quality acc. to WelChem

The quality calculation based on the WelChem cell model is available for all distributors. The drip points are evaluated in the grid of the packing and an integral value is determined for the first, 10th and 100th layer. The quality value calculated in this way indicates the quality in relation to the bed. It is therefore not an absolute distribution quality value.

Types of Liquid Distributors

TrayHeart can calculate all common liquid distributors. The types of distributor, channel distributor and distributor base represent the basic forms. Within these types of construction, the drip points can be defined as floor openings, tubes, wall openings and wall slots. The passage openings for the gas flow (round, square, with / without cover) can also be defined.

Pan Distributor

The basic dimensions of the pan distributor for small column diameters are defined by its diameter and height. The annular gap as well as any additional passage area placed as a gas chimney in the pan, as well as the liquid drip points (bottom openings, tubes with several levels of holes, wall holes with baffles) are defined.

Trough Distributor

The definition of trough distributors is based on templates (basic dimensions of the trough and its equipping with outlet openings). These are then assigned to the troughs in the layout and thus result in the distribution spectrum. Changes to the template have an immediate effect on the entire distribution layout.


In addition, the pre-distribution (parting box and calming insert) can be designed.

Deck Distributor

Similar to the channel distributors, the deck distributor is defined using templates (basic dimensions of the chimneys and the type/position of outlet openings). These are then assigned to the layout and thus result in the distribution spectrum. Changes to the template have an immediate effect on the entire distribution list.
