The invention relates to a packing layer (1) for structured packing (20), the packing layer (1) comprising a plurality of structural elements (2), and the structural elements (2) being shaped and arranged in such a manner that they form a first fine structure (3), and adjacent structural elements (2) having a first spacing (a), the packing layer (1) comprising a plurality of protrusions (4) that are shaped and arranged in such a manner that they form a second fine structure (5), and adjacent protrusions (4) having a second spacing (b). According to the invention, the structural elements (2) and the protrusions (4) are formed without perforations.
摘要:
A structured packing formed of a plurality of corrugated, rectangular sheets and a method relating to the use thereof. End regions of the corrugations are provided with straight, parallel corrugations extending inwardly from opposed edges of the sheets and a right angles thereto to reduce pressure drop at the interfaces between packing layers and thereby increase hydraulic capacity. Contact is promoted between descending liquid and ascending vapor phases within a main region of the corrugations that have straight, parallel sections of the corrugations oriented at an acute angle to the opposed edges. Transition regions having arcuate sections of the corrugations connect corrugations within the main and end regions to reduce internal pressure drop within the structured packing and thereby further reduce pressure drop at the interfaces and further increase the hydraulic capacity.

The present invention provides a vapor-liquid contact device for use in a distillation column and method incorporating the use of such a vapor-liquid contact device. The vapor-liquid contact device has arrays of elongated strips to support a falling film of a liquid and contact of a vapor with the film. The strips are supported in a structure having top and bottom sections connected to opposite ends of the strips. The top sections have apertures in registry with the strips so that liquid distributed to the top section seeps out of the apertures to initiate formation of the falling film. Openings are provided at the top and bottom sections, so that a vapor is able to pass through the support structure to contact the falling film to effect contact between the liquid and the vapor. Liquid distributors are associated with the top section to distribute the liquid to the apertures.

A method of mass transfer includes the steps of: supplying a first fluid and a second fluid into a mass transfer apparatus, wherein the mass transfer apparatus includes a vessel which has a head region, a base region and a mass transfer region, wherein the first fluid is brought into contact with the second fluid at least in the mass transfer region, wherein the mass transfer region is arranged between the head region and the base region and the mass transfer region includes a structured packing which includes a plurality of neighboring layers of fabric which includes fiber strands of a non-metallic material. The mass transfer apparatus is operated at a fluid load of at most 3 m3/m2/h. The fabric of the structured packing includes fiber strands of a non-metallic material which are formed as weft threads, wherein the weft threads have a yarn count of at least 100 g/1000 m and the weft threads include at least 20 yarns/25.4 mm.
摘要:
A cross-corrugated structure packing module is provided for use in mass transfer or heat exchange columns and has particular applicability in severe service applications in which fouling, coking, and erosion are of concern. The structured packing module has a plurality of upright, parallel-extending, corrugated plates. Spacer elements are used to maintain the corrugations of adjacent plates in spaced apart relationship to reduce the opportunity for solids to accumulate on the surfaces of the plates. The plates are also free of apertures or surface treatments that would increase the opportunity for solids to accumulate on the plates.

A tubular reactor and method for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.
