Abstract: A valve for carrying out a mass-transfer process, in which a gas flows through liquid standing on a separating tray, when the gas supply is interrupted the liquid flows into a lock and, when the gas supply is restarted, the liquid flows out of the lock, wherein the valve contains a closing element which is designed in such a manner that, with the closing element in a first valve position, a first opening in a lower tray of the lock is closable, and the closing element is conducted in a first sleeve which is positioned between the upper tray bordering the lock and the lower tray in which sleeve, in the region of the lock, second openings are formed, and which projects over the upper tray and has a lift limiter for the closing element.

Abstract: The invention relates to a method for carrying out a mass-transfer process in a column (1) comprising at least two separating trays (5), wherein each separating tray (5) comprises an upper tray (7) and a lower tray (9), and between the trays (7, 9) a lock (13) is formed, and valves (11) are provided which are designed in such a manner that a gas can flow through the separating tray (5), on interruption of the gas flow liquid flows from the upper tray (7) into the lock (13), and when gas supply is restarted, the liquid drains out of the lock (13), comprising the following steps: (a) flow of a gas exiting through valves (11) in the separating tray (5) through a liquid standing on the upper tray (7), wherein the amount of gas is high enough that no liquid flows back through the valve (11), (b) interruption of the gas supply in such a manner that the liquid runs through the valves (11) into the lock (13), (c) restart of the gas supply, wherein valves (11) in the lower tray (9) open, in such a manner that the liquid drains out of the lock (13), wherein the lock (13) is dimensioned in such a manner that the lock (13), after the liquid has drained from the upper tray (7) into the lock (13), is at most 70% filled with liquid. In addition, the invention relates to a valve for carrying out the method.
