Abstract: 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.

Abstract: The invention comprises an absorbent composition and process for purification of gaseous mixtures. The composition comprises a mixture of a physical absorption solvent and an ionic liquid. It was found that the mixtures provided improved absorption of a gas component, such as carbon dioxide, when compared physical absorption solvents.

Abstract: An anti-icing apparatus for use with an aerator or other in-water device is disclosed. The anti-icing apparatus uses perforated tubes to introduce ambient air into a body of liquid. Anti-icing tubes are positioned near the lower periphery of the sides of the aerator housing. A blower is used to supply ambient air to the anti-icing tubes. The anti-icing tubes produce a blanket of air bubbles around the housing and thus prevent the formation of ice around the aerator. The anti-icing apparatus may be used to protect various devices that must remain in a body of water during sustained periods of below-freezing temperatures.
