The present invention relates to a gas-redirecting device presenting an upper plane and a plurality of gas-redirecting tubes comprising an inlet end and an outlet end. For each gas-redirecting tube, the orthogonal projections of the inlet end and the outlet end onto the upper plane have an over-lapping area of at most 50% of the total area of the upper plane covered by the orthogonal projections. Also provided is a liquid-gas contacting column comprising a gas-redirecting device, a floating support comprising a liquid-gas contacting column, at least two packed beds and a method for improving the efficiency of a liquid-gas contacting column which is based on redirecting the gas from a wetted zone of a lower packed bed to a wetted zone of the higher packed bed.

The invention relates to a distributor tray (100) for a column for contact between a gas (G) and a liquid (L), comprising a plurality of compartments defined on one face of the tray by secant partitions (104) which are perforated (105) to allow the flow of liquid between adjacent compartments. Each compartment comprises at least one means for the passage of the liquid through the tray or a chimney (102) projecting from the tray for the exclusive passage of said gas (G) through the tray. The shape of the chimney is identical to the shape of the compartment containing it, and the chimney has an internal volume at least equal to the volume of the compartment containing it.

The invention relates to a gas/liquid separation column extending mainly along a vertical axis and comprising an external wall delimiting an internal space in which are arranged at least one first contact member in which the liquid and the gas are brought into contact and at least one dispensing device configured to collect the liquid resulting from the first contact member and to distribute it to a second contact member. At least one box for separating a two-phase fluid is arranged in the internal space of the column between the first contact member and the dispensing device against the wall of the column fed by a duct which passes through a wall of the separation box.

The invention is a tray 2 for a column for heat and/or matter exchange between a gas and a liquid, comprising at least one chimney 4 projecting from the upper part of tray 2 for exclusive passage of the gas through the tray, at least one means 5 enabling passage of the liquid through tray 2 and the inside of at least one of the chimneys providing exclusive gas passage being provided with a material dispersive towards said gas. The invention also relates to an exchange column comprising such a distributor tray and to the use of such a column.

The present invention relates to a distributor tray (2) for a column intended for heat and/or material exchange between a gas and a liquid. The tray comprises gas passage means (4), liquid passage means (6) and distribution means (5) for distributing the liquid with a preferred orientation. The invention also relates to a heat and/or material exchange column, and to the use of the column.

Disclosed is a vapor splitter including: a chimney tray dividing an internal space of a housing into an upper space and a lower space; a chimney provided on the chimney tray to enable the upper space and the lower space to communicate with each other; a cap covering the chimney with a gap therebetween such that a gas discharge hole is formed so that gas, coming out through the chimney, can be transferred to the upper space through the gas discharge hole; a liquid feeding unit for feeding liquid to the upper space; and a liquid discharging unit for discharging the liquid out of the upper space. The size of the gas discharge hole is adjusted by controlling the height of the liquid collected on the chimney. Further disclosed is a method of adjusting a vapor split ratio using the vapor splitter.

Provided is a packed column capable of achieving sufficiently high distillation performance even with the height of its gas-liquid contactors reduced. The packed column is a packed column which includes a gas-liquid contactor 17, 18 inside a tubular body 16 and a liquid distributor 19 in the upper most portion and causes descending liquid and ascending gas to contact each other in the gas-liquid contactor. The operation pressure is in the range of 200 to 1500 kPaG. The relative volatility is in the range of 1.9 to 3.1. The gas-liquid contactor is vertically divided into at least two parts. A gas disperser 20 is provided at at least one position between a lower one of the gas-liquid contactors and an upper one of the gas-liquid contactors, the gas disperser uniformly dispersing the composition of the ascending gas rising from the lower gas-liquid contactor toward the upper gas-liquid contactor.
