A fill sheet for cooling heat transfer fluid in a cooling tower includes an air intake end, an air outlet end, a top edge and a bottom edge. The air outlet end is positioned opposite the air intake end along a lateral axis. The top edge connects the air intake end and the air outlet end and the bottom edge also connects the air intake end and the air outlet end. The bottom edge is positioned opposite the top edge along a vertical axis. A plurality of flutes extends generally parallel to the lateral axis between the air intake end and the air outlet end. An offset extends generally parallel to the vertical axis. A first flute of the plurality of flutes transitions from a first peak at a first side of the offset to a first valley at a second side of the offset.

A jig for inserting a packing into a flow passage of a reactor extending in one direction or for removing the packing from the flow passage, includes: a pair of strip portions extending in parallel with each other, having a length longer than the flow passage; and link portions arranged in an extending direction of the pair of strip portions, linking the pair of strip portions and having lengths with which the pair of strip portions sandwich the packing therebetween.

A reformer tube for producing synthesis gas by steam reforming of hydrocarbon-containing feed gases, in which a structured stream reforming catalyst is used, is proposed. According to the invention, a heat exchanger tube is arranged in the interior of the structured catalyst, with the feed gas stream flowing firstly through the structured catalyst and subsequently in countercurrent through the heat exchanger tube. This improves the heat exchange between the synthesis gas product stream and the structured catalyst and the feed gas stream flowing through it, especially in the radial direction.
