Abstract: The present disclosure relates to a packing element, in particular for mass and/or heat exchange columns, through which at least one gas and/or at least one liquid flow flows, comprising a plurality of neighbouring strips curved inwards and/or outwards, wherein each strip is connected to the neighbouring strips at at least one end thereof. It is the object of the present invention to provide a packing element that is improved relative to the state of the art. According to the disclosure, this object is achieved in that at least one of the strips has an irregular shape.

Abstract: An assembly kit for installation of two column trays in a column with an upper column tray can include at least one first downcomer with at least one downcomer wall, and with a lower column tray which is disposed vertically spaced beneath the upper column tray and connected thereto. The assembly kit can include at least one column internals mounting angle having at least one first mounting point, at least one second mounting point, and an adjustment device for adjusting a vertical distance between the at least one first mounting point and the at least one second mounting point, where the column internals mounting angle is attached with the at least one first mounting point to the downcomer wall and is connected with the at least one second mounting point to the lower column tray.

Abstract: A process-technology column including a novel liquid distributor which is to be as insensitive as possible to dirt or solids carried in the liquid and which can be operated over a load range as great as possible without the possibility of the delivered liquid being excessively easily entrained by the gas flow which rises in the column is provided. The liquid distributor includes a liquid feed for conducting a liquid and at least 2 nozzles connected thereto for producing a respective liquid jet. The nozzles are flat-jet nozzles for producing a respective flat jet. The flat-jet nozzles are so oriented that the flat jet produced by them impinges on a drain element which is arranged at the liquid distributor and at which the liquid of the flat jet can drain away.

Abstract: A low-load distributor is disclosed for mass transfer columns for applying liquid onto the surface of packing stages of the mass transfer columns with at least one liquid supply, a plurality of liquid dispensing points and dwell time delay devices disposed between the liquid supply and the liquid dispensing points. An exemplery low-load distributor can be easily manufactured for a very low liquid flow rate and is characterized by high operation reliability. A dwell time delay devices can include absorbent open-pored storage material and the flow resistance of the storage material can increase in the liquid flow direction, starting from the liquid supply in the direction towards the liquid dispensing points.

Abstract: The present invention relates to a valve tray for mass transfer columns having a base plate, at least one liquid intake and at least one liquid outlet for forming a liquid flow having a direction of flow on the base plate, a plurality of gas entry orifices formed in the base plate and also a plurality of fixed valves covering the gas entry orifices, which fixed valves are formed in one piece with the base plate and in each case include a valve roof at a distance to the base plate and also a valve rear side and a valve front side, wherein between the base plate, the valve rear side, the valve front side and the valve roof of each fixed valve, at least one side gas outlet orifice is formed in each case. The side gas outlet orifices of the fixed valves can taper in the direction of flow of the liquid flow.

Abstract: The invention relates to a corrugated packing grid with consecutively arranged wave crests and wave troughs for a structured packing, which is assembled from several packing grids, for gas-liquid contacting apparatuses, and to a packing assembled from said packing grids. The aim of the invention is to provide a packing grid and a packing which have a large mass transfer area and a low pressure drop at the same time and which offer a high mechanical strength. According to the invention, this is achieved in that elements lie in the region of the wave troughs of the packing grid, said elements extending into the wave troughs.
