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.

An expandable center arrangement for a reactor is disclosed. The arrangement comprises an expansion tube; a center support inside the expansion tube and three or more spring elements. The spring elements are fastened to the center support and arc out to the expansion tube. A reactor is also disclosed.

The present invention discloses an efficient mass-transfer separation bulk filler structure, which includes a bulk filler body with closely-fit multilayer structures, wherein an annular wall surface of the bulk, filler body has a corrugated angle group. A lower portion of the bulk filler body is of a bell-mouth shape. Three passages with a same sectional area are formed inside the bulk filler body. The present invention has the characteristics of small pressure drop, large specific surface area, low liquid holdup and large void ratio. The annular wall surface is provided with the corrugated angle group to increase the disturbance and reduce a double-membrane thickness of vapor and liquid phase mass-transfer resistance, thereby improving the mass-transfer coefficient and separation efficiency. Meanwhile, by adopting the bell-mouth shape, the stability and natural stacking regularity of the bulk filler can be improved.
