[Also in Group XXVIII] A bubble plate in a gas-liquid contact column embodies a number of wells each with bubble caps &c. disposed over most of its area and dividing the plate into a number of cells in all directions across it, each well retaining a separate pool of liquid and having its own outlet. Each of a stack of bubbling plates is made up of triangular wells 150, 1501 with boundary walls 152 and a flat bottom 151, the wells being assembled edge to edge to form a closed pattern and a solder seal 154 applied to a V groove between abutting edges. Wells 150 of the top and alternate plates are drained by downcomers 157 at each corner and wells 150<SP>1</SP> of the second and alternate plates drain from the centre by downcomers 158 ; or each plate may have both types of well. Bubble caps 160 are located over vapour risers in the well floor. Spaces 161 remaining between marginal walls and the column wall are closed preferably by sheet metal. The lowermost plate of a stack is mounted on a grid structure of bars arranged in triangles each supporting four wells on small plates welded to the bars at intervals the length of the side of a well, each plate thus supporting a corner of six wells. Succeeding bubble plates are spaced by telescoping cylindrical spacers 186, 187, at the well corners, vertical slots being provided in the lower cylinder so as to fit over the meeting walls of the wells. In assembling the first plate a spacer is adjusted in height by screwing in the upper cylinder the correct amount, the parts then being soldered and the top used as a reference surface for two additional spacers to provide a level support for the first well.

Method and apparatus for the separation of air.

Gaseous mixture i.e. air, separating method for low pressure column of double air separation column, involves generating magnetic field of electromagnet to partially compensate hydrostatic pressure of liquid bath

The method involves sending boil-up gas i.e. gaseous nitrogen (GAN), to an evaporator-condenser (13) of a low pressure column (1), and evaporating liquid oxygen (LOX) by heating a liquid bath with the evaporator-condenser. A magnetic field of an electromagnet is generated to partially compensate the hydrostatic pressure of the liquid bath. A distillation is carried out in a double column comprising an average pressure column and the low pressure column thermally connected with each other by the evaporator-condenser. An independent claim is also included for a cryogenic distillation apparatus for separating a gaseous mixture by cryogenic distillation in a low pressure column.

Divided wall exchange column

A divided wall exchange column includes a dividing wall strengthened by stiffening members and/or a double wall design to better withstand pressure differentials and minimize temperature differentials. When a double wall is used, cost of manufacture and installation is minimized by reducing the manufacturing tolerances required while providing a design robust in construction, installation, and operation. When structured packing is used, the stiffening members, combined with positioning the layers of packing at preferred angles relative to the dividing wall, result in minimal interference with the heat and/or mass transfer process while minimizing the complexity of manufacture and construction of the packing. Further, by positioning the top layer of structured packing at other preferred angles relative to the dividing wall, a simplified liquid distributor design may be used in the divided wall exchange column while the layers below may still be orientated as described above with all the ...

The two-stage liquid distribution device includes a lower distributor with a lower parting box and lower troughs and an upper distributor with an upper parting box and upper troughs. The lower and upper parting boxes and troughs are enclosed to allow a liquid head in a lower downpipe section and an upper downpipe section that feed liquid to the lower distributor and the upper distributor to cause pressurization of liquid within the lower and upper parting boxes and troughs. The pressurization makes the lower and upper distributors less susceptible to rocking motion of the mass transfer column and reduces any maldistribution of liquid discharged from the lower and upper troughs to the mass transfer bed.

Divided Wall Exchange Column

A divided wall exchange column includes a dividing wall strengthened by stiffening members and/or a double wall design to better withstand pressure differentials and minimize temperature differentials. When a double wall is used, cost of manufacture and installation is minimized by reducing the manufacturing tolerances required while providing a design robust in construction, installation, and operation. When structured packing is used, the stiffening members, combined with positioning the layers of packing at preferred angles relative to the dividing wall, result in minimal interference with the heat and/or mass transfer process while minimizing the complexity of manufacture and construction of the packing. Further, by positioning the top layer of structured packing at other preferred angles relative to the dividing wall, a simplified liquid distributor design may be used in the divided wall exchange column while the layers below may still be orientated as described above with all the associated benefits.
