摘要:
An apparatus includes an inlet, an outlet, and a sheet disposed proximate a heat transfer surface, wherein the sheet is oriented in a sheet plane that is displaced from a plane of the heat transfer surface by an angle of at least 10 degrees. The apparatus also includes a plurality of tabs attached to the sheet, the tabs lying in respective tab planes, wherein the tab planes and the sheet plane intersect forming respective intersections. The intersections of the tab planes and the sheet plane are substantially parallel. The intersections of the tab planes and the sheet plane are at an angle of less than 88° to the heat transfer surface, and the plurality of tabs collectively form channels directing a fluid passing from the inlet to the outlet to impinge the heat transfer surface.

Heat integrated distillation column for separating components in a fluid mixture. The heat integrated distillation column is provided with a stripper part (S), a rectifier part (R) and a compressor (2) between the stripper part (S) and the rectifier part (R). Furthermore, a heat exchange assembly for transferring heat between the stripper part (S) and the rectifier part (R), and a mass transfer assembly for condensation and vaporization in the heat integrated distillation column are provided. The stripper part (S), the rectifier part (R), or the stripper part (S) and rectifier part (R), comprise a channel formed by adjacent channel assemblies (6), each forming a structural part of the heat integrated distillation column and a functional part of the heat exchange assembly and of the mass transfer assembly. A plate (8) and a structured packing in the form of two or more corrugated plates (7) are provided.

A catalytic reactor (40) comprising a plurality of flat metal sheets (42) arranged as a stack and bonded together, the sheets being shaped so as to define first flow channels (44) between adjacent sheets and to define second flow channels between adjacent sheets, first flow channels alternating with second flow channels in the stack, and such that there is good thermal contact between fluids in the first and the second flow channels; headers to supply fluids to the flow channels, the headers enabling different fluids to be supplied to the first and the second flow channels; wherein a permeable metal heat-transfer layer is provided within each flow channel, the metal heat-transfer layers (42)being removable and incorporating a catalytic coating; the catalytic coating in the second flow channels comprising a combustion catalyst, such that a gas mixture flowing in the second flow channels undergoes catalytic combustion, and wherein the combustion catalyst at least at the start of the channel is coated with a thin porous inert ceramic layer to restrict the contact of the gas mixture with the catalyst and so restrict the reaction rate.
