Disclosed is a method for deodorising organic or inorganic fluids (such as edible oils, vegetable fats or oils, animal fats or oils, fish oils, mineral oils etc.) comprising creating a continuous flow or semi continuous flow of the fluids through a column having one or more trays, creating a plug flow of the fluids through a labyrinth of passages on each tray by regulating the flow through the passages by use of a regulating valve at an exit in the tray, introducing sparging gas on the bottom level of each tray, contacting the fluids with the sparging gas in the plug flow, removing volatiles from the fluids, and transferring the sparging gas and the volatiles in a duct inside the column or outside the column. Further disclosed are plug flow trays and a columns containing them for use in deodorising organic or inorganic fluids.
