| 20130043010 | STRUCTURED PACKING MODULE FOR MASS TRANSFER COLUMN AND PROCESS INVOLVING SAME - 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. | 02-21-2013 |
| 20120292791 | USE OF DOWNCOMER BEAM TO SUPPORT ADJACENT CROSS FLOW TRAYS WITHIN A MASS TRANSFER COLUMN AND PROCESS INVOLVING SAME - Cross flow trays in a mass transfer column are provided with downcomers having one or more walls that extend from a tray deck of one the cross flow trays to an elevation below a tray deck of an underlying one of the cross flow trays. The downcomer walls are connected to and provide structural support for the tray decks of the cross flow trays. | 11-22-2012 |
| 20120228251 | APPARATUS FOR SUPPORTING INTERNALS WITHIN A MASS TRANSFER COLUMN AND PROCESS INVOLVING SAME - An elongated support beam is provided for supporting internals such as liquid collectors, liquid distributors, packing supports, or trays within a mass transfer column. The support beam is divided longitudinally into a lower beam segment and an upper beam segment that are joined together by a plurality of connectors at one or more longitudinally spaced-apart positions. The connectors serve to stiffen and resist lateral deflection of the lower and upper beam segments in relation to each other and to transfer the load carried by the upper beam segment to the lower beam segment or vice-versa. By dividing the support beam into lower and upper beam segments, each of the lower and upper beam segments can be passed through a manway opening in a shell of the mass transfer column prior to assembly of the support beam or following disassembly of the support beam within the mass transfer column. | 09-13-2012 |
| 20120175792 | CONTACT TRAY AND METHOD EMPLOYING SAME - A contact tray is provided with a tray deck and dividing walls which form groupings of one or more cans and one or more downcomer inlets distributed across the tray deck. The cans have walls that surround vapor openings in the tray deck that permit upward passage of a vapor stream into the cans. Downcomers extend downwardly from the downcomer inlet and are positioned for delivering a liquid stream into the center of cans positioned on a tray deck of an underlying contact tray. Discharge openings are provided in the walls of the cans to allow the liquid stream to exit the cans. The dividing walls direct the exiting liquid stream into the downcomer inlets in the same grouping and prevent or impede the liquid stream from flowing to a low side of the tray deck. | 07-12-2012 |
| 20120111717 | LIQUID COLLECTION AND DISTRIBUTION DEVICE FOR MASS TRANSFER COLUMN AND PROCESS INVOLVING SAME - A liquid collection and distribution device is provided to support a bed of packing material and to collect liquid exiting the bed and redistribute it to an underlying bed of packing material with improved compositional and volumetric flow uniformity. The liquid collection and distribution device includes a liquid collector, a liquid distributor, and a lattice-type framework positioned between and supporting the liquid collector and the liquid distributor. In addition to supporting the liquid collector and liquid distributor, the framework has internal fluid passages that convey the liquid from the liquid collector to the liquid distributor while shielding the liquid from ascend vapor or gas flow. | 05-10-2012 |
| 20100230832 | RANDOM PACKING ELEMENTS AND COLUMN CONTAINING SAME - A saddle-shaped random packing element is provided with laterally spaced, arcuate side members and a plurality of inner and outer rib elements that extend from and between the side members to form an interior volume. At least one lesser rib element extends from the side members and is at least partially positioned within the interior volume so that at least about 20 percent of the surface area of the packing element is positioned within the interior volume. | 09-16-2010 |
| 20100065501 | STRUCTURED PACKING MODULE FOR MASS TRANSFER COLUMN AND PROCESS INVOLVING SAME - 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. | 03-18-2010 |
| 20100039881 | CROSS-FLOW TRAY AND METHOD EMPLOYING SAME - A cross-flow tray is provided with a tray deck and groupings of cans separated by weirs. The cans have walls that surround vapor openings in the tray deck. Openings are provided in the walls to allow liquid to enter the cans from the tray deck. Additional openings are provided in the walls to allow liquid to exit the cans. Swirlers positioned within the cans induce a centrifugal swirling motion to the vapor and liquid to facilitate mass transfer and/or heat exchange between the vapor and liquid within the cans. | 02-18-2010 |
| 20090071337 | TWO-STAGE MIST ELIMINATOR AND METHOD - A two-stage blade-type mist eliminator is provided. In general, both stages include a plurality of impingement blades arranged to form a vaulted or inverted V-shaped profile. The first stage defines a larger included angle than the second stage. Advantageously, the corresponding terminal ends of each stage can be supported by a common support member. | 03-19-2009 |
