Abstract

The present invention relates to a high performance liquid distributor comprising: a feed pipe, which supplies a liquid flowing from the outside of a reactor or a fractionation column, or a collector tray, which collects a liquid flowing from the outside or a liquid falling from an upper part of the column; a catch pan introduced from the feed pipe or the collector tray; and two or more down pipes which are divided into several pipes and supplying the liquid to a liquid distributor connected to the lower side. Therefore, the liquid is equally distributed to the whole area of the distributor if a support ring in the distributor is not installed horizontally, thereby maximizing gas-liquid contact and increasing efficiency and the amount of the liquid distributed to each divided pipe of the liquid distributor is equal in a floating production storage and offloading (FPSO) with the shaking of the distributor, thereby keeping an even distribution of the liquid.

Description

TECHNICAL FIELD [0001] The present invention relates to a high-performance liquid distributor,

The present invention relates to a high-efficiency liquid distributor, and more particularly to a liquid distributor for use in a fractionation column and related apparatus among fluid contact and dispersing apparatuses, As a distributor of a distillation column for separating substances using distillation, absorption and cooling principles in a distillation tower, a washing tower and an absorption tower for removing and separating fine chemicals and noxious gases or organic matters, And more particularly, to a high-efficiency liquid dispensing apparatus for maximizing efficiency of vapor-liquid contact by maximizing the efficiency of vapor-liquid contact.

Currently, there are columns which are used industrially for distillation, absorption and cooling. These columns are devices for separating or absorbing a desired substance through vapor-liquid contact.

Particularly, an apparatus constituting the inside of the column for facilitating gas-liquid contact is referred to as a tower internal, and representative examples thereof include a tray and a packing.

Examples of the packing include random packing, structured packing, and grid packing. In general, the structured packing has a high efficiency and a large processing capacity, and the grid packing is processed Although the capacity is large, the efficiency is low and the use is limited to a specific use.

The packed column includes a packing support for supporting the packing, a bed limiter for preventing flow to the upper part, a liquid distributor for uniformly dispersing the liquid in the packing, (Liquid Distributor).

The liquid distributor is a tower interior that has the greatest influence on the performance of the packing. The liquid distributor has a variety of structures depending on the conditions. Particularly, in the FPSO, the liquid distributor is not flat (Pipe Orifice Type) is widely used because the uneven distribution of the liquid is required to minimize the liquid level difference.

The configuration, function and operation of a conventionally used pipe orifice type liquid dispensing apparatus will be described below.

FIGS. 1A to 1C are views showing a liquid distributor according to a first embodiment of the present invention, and FIGS. 2A to 2C are diagrams showing a liquid distributor according to a second embodiment of the present invention 3A to 3C are views showing a liquid distributor according to a third embodiment of the present invention.

The liquid flowing from the upper or the lower collector tray 500 is discharged through a pipe orifice 100 through a feed pipe 100 or a down pipe 300, Orifice Type) liquid dispenser 400. The liquid dispenser 400 is connected to the liquid dispenser 400 via a liquid supply pipe (not shown).

The liquid 10 transferred to the catch pan is transferred to a main header pipe 410 and is supplied to each of the side pipes connected to the main header pipe 410 And 420 and is distributed to the upper portion of the packing through a nipple pipe 430 formed at the lower end.

When the diameter of the column is large, a distance from the catch pan is increased due to pressure drop in the distributor lateral pipe 420 of the distributor, The amount of the liquid (liquid) 10 to be dispensed may be different.

Therefore, the number of catch pan (Catch Pan) should be more than two.

FIG. 4A is a front view showing a vertical state of a liquid distributor according to a third embodiment of the present invention, and FIG. 4B is a front view showing a state in which the liquid distributor according to the third embodiment of the present invention is tilted Is a front view showing the dispensing state of the liquid.

Referring to FIGS. 4A and 4B, as a distribution apparatus used in the FPSO among liquid distribution apparatuses, a floating production storage and offloading (FPSO) is generally used for a marine plant or a drillship The FPSO is a special ship capable of refining crude oil extracted from a tanker and storing it in a shuttle tanker or other transporting area. The FPSO produces and processes the lower hull structure (Hull) (Topsides) that function as a facility.

In the case of such an FPSO, a liquid level difference occurs between the catch pan and the main header pipe connected to each catch pan when the sea structure or ship is shaken by the wind or wave, The amount of the liquid 10 supplied to the lateral pipe 420 and the amount of the liquid supplied to the lateral pipe 420 may be different from each other and the liquid in the nipple pipe 430 at the lower end of the lateral pipe 420 , 10) is different for each drop point (Drip Points).

In addition, a support ring welded to the inside of the column for installation of a collector tray in the case of an onshore plant or a column installed in an FPSO is tilted due to manufacturing problems, The level of the collector tray installed thereon is also tilted.

That is, since the liquid level of each down pipe is different from that of the collector tray, the amount of the liquid supplied to the liquid distributor mounted on the lower portion of the down pipe varies even if the column is not shaken.

Ultimately, if the amount of liquid to be supplied to the packing under each drip point is changed, the performance of the packing is remarkably deteriorated to deteriorate separation and absorption.
