Publication number: 20240116022Abstract: A structured packing element for a column for at least one of mass transfer and heat exchange between a heavy fluid phase and a light fluid phase. The structured packing element comprises at least two layers of a grid comprising openings that are surrounded and separated from each other by separating elements. At least two of the layers are arranged in a longitudinal direction parallel and in touching contact with each other such that an open space extending from one end to an opposite end of the layers is provided between the layers such that at least one of the heavy fluid phase and the light fluid phase may flow therethrough. An average width of at least 50% of the separating elements between adjacent openings is at least 15 times a layer material thickness and is between 70% and 125% of an average hydraulic diameter of the adjacent openings.Type: ApplicationFiled: September 28, 2020Publication date: April 11, 2024Inventors: Marc WEHRLI, Ilja AUSNER, Florian KEHRER, Markus DUSS

Patent number: 8944417Abstract: A packing layer for a structured packing which has corrugations forming open channels. Each channel includes first and second corrugation peaks bounding a first corrugation valley with each corrugation peak having an apex and the corrugation valley having a valley bottom. A spacer element is mounted on and extends along the apex of at least one corrugation peak. The spacer element has an edge which has a larger normal spacing from the valley bottom than, the spacing of the apex of the corrugation peak from the valley bottom.Type: GrantFiled: March 18, 2010Date of Patent: February 3, 2015Assignee: Sulzer Chemtech AGInventors: Ilja Ausner, Markus Duss

Publication number: 20140322115Abstract: The invention relates to a method of performing a carbon dioxide absorption with reduced risk of aerosol formation from a carbon dioxide containing stream in an absorption apparatus having a specific sequence of sections and wherein the method comprises specific steps. Another aspect of the invention relates to a use of a structured packing as part of a carbon dioxide absorption section in an apparatus for the absorption of carbon dioxide, characterized in that the use is in reducing the risk of aerosol formation in a top region of the carbon dioxide-absorption section. Yet another aspect of the invention is a use of an absorption apparatus comprising a specific sequence of sections, wherein the use is for avoiding a super-saturation of a solvent and water and a risk of aerosol formation.Type: ApplicationFiled: October 11, 2012Publication date: October 30, 2014Inventor: Markus Duss

Patent number: 8746660Abstract: An absorber or desorber contains a layer (10) for a structured packing which has corrugations, wherein a plurality of open channels (12, 14, 16) is formed by the corrugations, wherein the channels include a first corrugation valley (22), a first corrugation peak (32) and a second corrugation peak (42). The first corrugation peak (32) and the second corrugation peak (42) bound the first corrugation valley (22), wherein the first and second corrugation peaks have a first apex (33) and a second apex (43). An indentation (34) extending in the direction of the first apex (33) is formed on the first apex (33) of the first corrugation peak (32). The first corrugation valley (22) has a valley bottom (23), wherein the normal spacing (27) of at least one point of the indentation (34) from the valley bottom (23) of the corrugation valley (22) is smaller than the normal spacing (28) of the first apex (33) from the valley bottom (23) of the corrugation valley (22).Type: GrantFiled: March 17, 2010Date of Patent: June 10, 2014Assignee: Solzer Chemtech AGInventors: Ilja Ausner, Markus Duss, Raymond Plüss
