Abstract: A system, including: a recirculated exhaust gas conditioning loop that routes exhaust gas from a heat recovery steam generator to a turbine compressor inlet, wherein the recirculated exhaust gas conditioning loop includes an exhaust gas conditioning device that cools the exhaust gas and removes particulate matter from the exhaust gas, and a dehumidifier that dehumidifies the exhaust gas.

Abstract: Method and system is described for enhanced oil release management system by using one or more booms, one or more skimmers and one or more floating burners. The method and system may include skimmers to capture a fluid that is supplied to the floating burner.

Abstract: The invention involves a spacing element situated between a vapor-liquid contacting tray and a tray support to reduce the dead zone typically caused by the tray supports blocking of the perforations in the vapor-liquid contacting tray directly above the tray support.

Abstract: The performance of multiple downcomer fractional distillation trays is improved by intercepting the liquid egressing from the bottom of the downcomers in a manner which directs a portion of the liquid along the major axis of decking of the next lower tray. This is accomplished by the use of improved antipenetration pans suspended below the downcomers of the upper tray. The antipenetration pans have extensions running parallel to the decking areas of the next lower tray. A portion of the liquid falling from the upper downcomer flows to the end of the extensions, where it falls onto the lower decking at more distant points than with prior art antipenetration pans.

Abstract: Liquid distributors collect liquid falling out of the spout group at the ends of a downcomer of a fractionation tray. The devices then distribute the liquid against the wall of the column or onto the decking of the next lower tray so to cause uniform liquid flows across the terminal decking section of the next lower multiple downcomer tray. The apparatus improves the liquid flow path on the terminal decking section of the tray, thus increasing the overall efficiency of the tray.

Abstract: The efficiency of multiple down comer fractional distillation trays is improved by distributing the liquid egressing from the bottom of the downcomers in a manner which provides a uniform length liquid flow path on the next lower tray. This is accomplished by liquid distribution devices suspended below the downcomers of the upper tray, with the devices running parallel to the downcomers of the next lower tray and being adapted to collect the falling liquid and then disperse it onto the decking below along the length of the lower downcomers through openings in the distribution device.

Abstract: A novel fractionation column (1) internal structure consists of groups of fractionation trays in which the upper trays rest upon the bottommost tray of the group, which is the only tray of the group supported by the column wall. Preferably the downcomers (13) or disengagement plates of the upper tray rest upon the tops of the downcomers (13) of the next lower tray. Only the bottom tray is supported as by a ring (12) attached to the column.

Abstract: A novel fractionation tray (1) includes slidable decking plates (4) located between and alongside parallel downcomers (2). The decking plates located between a pair of downcomers have sections which may be extended outward toward the edge of the tray to adapt the shape of the tray to the internal shape of the column in which it is installed. A method of installing the trays, with an upper tray being supported only by a lower tray, is also disclosed.

Abstract: A novel fractionation column (1) internal structure consists of bundles of fractionation trays in which each upper tray rests upon the next lower tray. Only the lowermost tray of the bundle is supported by the column wall. Preferably the downcomers (13) of the upper tray rest upon the tops of the downcomers (13) of the next lower tray. The two crescent-shaped terminal decking sections (19) on opposite edges of the tray are supported from below by arch-shaped structures (17) anchored to the next lower tray.

Abstract: High vapor and liquid capacity counterflow fractionation trays demonstrating superior turndown and performance characteristics include a number of parallel downcomers separated by planar tray decking having unique bidirectional slotted cap valve geometries. Several different arrangements of the bidirectional valves are presented. The raised trapezoids of the bidirectional valves may be arranged in two groups which each face the nearest downcomer, or arranged in lines parallel to the downcomer sidewalls such that trapezoids of neighboring rows face opposite directions. In a third embodiment these bidirectional slotted cap valves are only located in the regions of the decking sections located next to the downcomers.
