Battery charging system comprising a hydrogen source module adapted to provide gaseous hydrogen; a hydrogen fuel cell power module comprising a hydrogen fuel cell and a power delivery outlet unit adapted to transfer power generated by the fuel cell to a secondary battery for recharging the secondary battery; and coupling and transfer means adapted to connect and disconnect the hydrogen source module and the hydrogen fuel cell power module.

Modular portable battery charging system using hydrogen fuel cells

A structured packing element has at least one edge adapted to intermesh with an edge of at least one other structured packing element. The structured packing elements may be used in a packed section in an exchange column which includes: a first layer of structured packing including a first structured packing element having an upper edge adapted to intermesh with a generally vertically adjacent lower edge of a second structured packing element; and a second layer of structured packing located above the first layer of structured packing, the second layer including the second structured packing element having the lower edge adapted to intermesh with the generally vertically adjacent upper edge of the first structured packing element. The upper edge of the first structured packing element intermeshes with the lower edge of the second structured packing element.

Structured packing with increased capacity

An apparatus for collecting and redistributing a flow of a liquid descending in an exchange column containing a layer of structured packing and having a longitudinal axis, a cross-sectional area, and an inner wall having an inner perimeter, includes: a wall-flow collector located above the layer of structured packing, the wall-flow collector having an outer perimeter adjacent the inner perimeter of the inner wall and being adapted to collect at least a portion of the liquid descending on or near the inner wall of the exchange column; a transmission means for transmitting at least a portion of the collected liquid collected by the wall-flow collector toward the longitudinal axis a substantial distance across the cross-sectional area of the exchange column; and a dispensing means for dispensing at least a portion of the portion of the collected liquid from the transmission means to the layer of structured packing.

Wall-flow redistributor for packed columns

A method of installing a structured packing in an exchange column, the structured packing having a surface area density in the range of about 500 m /m to about 675 m /m includes a plurality of corrugated plates disposed in vertically parallel relation. Each plate has at least one aperture and a plurality of regularly spaced and substantially parallel corrugations disposed in crisscrossing relation to the corrugations of an adjacent plate. The apertures have an equivalent diameter of less than about 4 millimeters but greater than about 2 millimeters. The corrugations have a corrugation angle (&agr;) relative to horizontal in the range of about 40&deg; to about 60&deg;. Each corrugation, when approximated to be substantially a triangular cross-section, has an included angle (&bgr;) defined by two sides of the corrugation in the range of about 90&deg; to about 100&deg;. The structured packing is used in exchange columns for exchanging heat and/or mass between a first phase and a second phase in processes such as cryogenic air separation.

Optimal corrugated structured packing

A structured packing having a surface area density in the range of about 500 m /m to about 675 m /m includes a plurality of corrugated plates disposed in vertically parallel relation. Each plate has at least one aperture and a plurality of regularly spaced and substantially parallel corrugations disposed in crisscrossing relation to the corrugations of an adjacent plate. The apertures have an equivalent diameter of less than about 4 millimeters but greater than about 2 millimeters. The corrugations have a corrugation angle (&prop;) relative to horizontal in the range of about 40&deg; to about 60&deg;. Each corrugation, when approximated to be substantially a triangular cross-section, has an included angle (&bgr;) defined by two sides of the corrugation in the range of about 90&deg; to about 100&deg;. The structured packing is used in exchange columns for exchanging heat and/or mass between a first phase and a second phase in processes such as cryogenic air separation. A method also is provided for installing the structured packing in an exchange column
