A liquid distributor and method for distribution of a liquid in a mass transfer column, the distributor includes at least one riser comprising at least one riser wall, the at least one riser wall extends from a first surface of the distributor in a first direction of the mass transfer column; at least one shield, the at least one shield extends from a second surface of the distributor opposite the first surface and extending in a second direction opposite the first direction; and at least one liquid distribution aperture extending from the first surface of the distributor through the second surface of the distributor, the at least one shield has a length extending in the second direction such that a gap is created between the at least one shield and a packing, the height of the gap between the shield and the packing is about 10 mm to 75 mm.

Shielding in a separation column

At least one section of structured packing where the length of the section is about 1 m to about 6 m; and where the specific surface area of the structured packing of the section is greater than 500 m/m, is used in a vapour/liquid contact column operating in locations where environmental conditions adversely affect steady state operation of the column to reduce maldistribution of liquid in the column under motion. The structured packing section has particular application offshore on a buoyant platform where tilt of the column out of vertical alignment due to the rolling motion of the platform can significantly affect the efficiency of the column.
