The invention relates to a fluidizing plate, comprising a supporting structure and plate segments, the plate segments respectively having openings through which gas flows during operation. The plate segments are respectively releasably connected to the supporting structure and two neighboring plate segments respectively overlap and are releasably connected to one another in the region of the overlap. The invention also relates to an apparatus with such a fluidizing plate.

Fluidizing plate and apparatus comprising such a fluidizing plate

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.

Method for carrying out a mass-transfer process in a column

The invention relates to a valve for carrying out a mass-transfer process in which a gas () flows through a liquid () standing on an upper tray (), when the gas supply is interrupted the liquid () flows into a lock () beneath the tray () and, when the gas supply is restarted, the liquid () flows out of the lock () through a lower tray () bordering the lock () downward, wherein the valve () comprises a closing element () which comprises a piston rod (), an upper valve disk () and a lower valve disk (), and which is conducted in a sleeve (), wherein the lower valve disk (), in a first valve position, closes an opening () at the lower end of the sleeve (). The upper valve disk () and the lower valve disk () are each movably connected to the piston rod ().

Valve for carrying out a mass-transfer process

The invention relates to a column for carrying out gas/liquid mass-transfer processes, wherein, in the column (), at least one lock () bordered by an upper separating tray () and a lower separating tray () is received, which lock is designed in such a manner that, during the mass-transfer process, gas () flows through the lock () and a liquid () situated on the upper separating tray (), when the gas supply is interrupted the liquid () flows into the lock () onto the lower separating tray () and when the gas supply is renewed, the liquid () drains downward out of the lock (). The lower separating tray () has a tray () that can be mounted so as to be fixed and has at least one opening (), and a rotatable tray () which is connected to a rotatable axle () that is conducted through the tray () that can be mounted so as to be fixed, in such a manner that the rotatable tray () can be turned in relation to the tray () that can be mounted so as to be fixed, wherein the rotatable tray () of the lower separating tray () is designed in such a manner that the at least one opening () in the tray () that can be mounted so as to be fixed is closed in a first position of the rotatable tray () and can be opened by turning the rotatable tray ().
