  • Patent number: 9314709
    Abstract: In existing structured packing, performance depends on effective contacting area. Performance decreases in cases having high surface tensions such mixtures containing a lot of water. Such mixtures are difficult to wet the packing surface. The present invention prevents liquid from intersecting the crease of the corrugation and from falling into a free space. Further, liquid flowing into the slot makes frequent liquid and vapor interfacial update resulting in positive utilization of the wetted area. The most important point of this invention is taking a positive utilization of the wetted area. The most important point of this invention is taking a large value of 3.5 or more of P/H (pitch/height of the crimp) and providing the horizontal slot on the crease, resulting in adding the flow reversal mechanism and frequent interfacial update.

    Abstract: A low pressure drop structured packing sheet with diversion windows, which are formed on both crests and troughs. When in the expanded state where the diversion window and packing sheet are flat on the same plane, the diversion window has an opening and a fan-shaped portion, with the area of the opening being 0%-1000% of that of the fan-shaped portion. Two side intersection lines between the fan-shaped portion and packing sheet is symmetrical with respect to a central folding line which divides the fan-shaped portion into a left part and a right part. The two side intersection lines intercept to each other with an angel of about 10°-170°. When in the operating state where the diversion window and packing sheet are partially folded towards opposite directions, the fluid at the trough flows to a crest of the other side of the packing sheet with the help of diversion windows, thus increasing the area of vapor-liquid mass transfer.

    Abstract: [Object] In the existing structured packing, performance depends on the effective contacting area and it decreases in case that large surface tension mixture such as with a lot of water since such mixture are difficult to wet the packing surface. Also they have poor performance for relatively higher liquid load at atmospheric pressure or less and for high pressure system where the ratio of liquid/vapor load becomes relatively higher than non-high-pressure system. [Means for Solution] Summarized are the objects to be solved as follows. (1) Prevention liquid from intersecting the crease of the corrugation to fall into a free space. (2) Liquid flowing in to the slot makes frequent liquid and vapor interfacial update. (3) Positive utilization of wetted area. The most important point of this invention is taking a large the value 3.5 or more of P/H (pitch/height of the crimp) and providing the horizontal slot on the crease, resulting in adding the flow reversal mechanism and the frequent interfacial update.

  • Patent number: 8690130
    Abstract: A structured sheet cross flow media is formed with a first corrugated sheet having corrugations defining flutes angled in a first direction, a second corrugated sheet defining flutes angled in a second direction, and an interstitial planar sheet disposed between the first and second corrugated sheets. The interstitial planar sheet traps the flow of fluid or gas, such as air, entering one end of the media block within opposing flutes until the end of the interstitial sheet is reached, whereupon the fluid or gas can disperse between the intersecting flutes of the first and second sheets to provide a controlled dispersal of the fluid or gas. In one embodiment, the interstitial sheet terminates at an intermediate height in the media block to define the width of dispersion of air bubbles entering at a single source point.

  • Patent number: 8646758
    Abstract: The invention is a method of formation and a structured packing for a fluid exchange column, which defines an exchange surface for at least one descending liquid phase to be placed in intimate contact with at least one ascending gaseous phase. The packing comprises a stack of plates having undulations, each plate being contained in a space included between two parallel planes L1 and L2 separated by a value of between 5 and 50 mm. The undulations are distributed on both sides of a center plane P separating the space into two equal parts and form a series of channels which extend along a direction D. The channels comprise wings contained in the space included between the two parallel planes. Each wing is composed of a strip B punched out in one of the channels according to at least two grooves C1 and C2. The width of the strip between the two grooves is between 1 and 15 mm.

    Abstract: 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.

    Abstract: A heat exchanger plate includes a corrugated sheet of stiff material configured in a repetitive series of elongated corrugations. Each corrugation has a first corrugation segment, a second corrugation segment disposed offset from and extending parallel to the first corrugation segment and an intermediate corrugation segment. The first and second corrugation segments extend vertically. The intermediate corrugation segment is disposed between and interconnects the first corrugation segment and the second corrugation segment and extends obliquely relative to the first corrugation segment and the second corrugation segment to form a continuous, uninterrupted offset corrugation. A plurality of the heat exchanger plates are connected together to form a fill pack.
