摘要： A component of at least one of two fluids is transferred into the other by introducing a liquid onto the surface of fibers extending generally linearly along a conduit with the fibers filling the cross-sectional area of at least a portion of the length of the conduit and being wetted by the liquid, flowing a gas through the conduit past the fibers thereby dragging a film of the liquid along the fibers, collecting the liquid in a gravity separator approximate the downstream end of the fibers and then separately removing the two fluids from the separator.

摘要： This invention is an improved gas-absorption process for the recovery of a desired component from a feed-gas mixture containing the same. In the preferred form of the invention, the process operations are conducted in a closed-loop system including a gas-liquid contacting column having upper, intermediate, and lower contacting zones. A liquid absorbent for the desired component is circulated through the loop, being passed downwardly through the column, regenerated, withdrawn from a reboiler, and then recycled to the column.A novel technique is employed to concentrate the desired component in a narrow section of the intermediate zone. This technique comprises maintaining the temperature of the liquid-phase input to the intermediate zone at a sufficiently lower value than that of the gas-phase input to the zone to effect condensation of a major part of the absorbent-vapor upflow to the section. This establishes a steep temperature gradient in the section. The stripping factors below this section are selected to ensure that virtually all of the gases in the downflowing absorbent from the section are desorbed. The stripping factors above the section are selected to ensure re-dissolution of the desired component but not the less-soluble diluent gases. As a result, a peak concentration of the desired component is established in the section, and gas rich in that component can be withdrawn therefrom.The new process provides important advantages. The chief advantage is that the process operations can be conducted in a single column in which the contacting zones operate at essentially the same pressure.

摘要： A surface layer is formed on transfer elements of the rotor of a humidity and heat exchanger rotor, the layer not only being hygroscopic to provide the desired humidity transfer, but also serving as a bonding agent or cement for holding the transfer elements together in the desired rotor configuration. A preferred layer uses as a bonding agent a solution of cellulose acetate or nitrate in acetone, and with lithium chloride dissolved therein to produce the hygroscopic effect.

摘要： A process for the removal, from gaseous mixtures, of a desired component selected from oxygen, iodine, methyl iodide, and lower oxides of carbon, nitrogen, and sulfur. The gaseous mixture is contacted with a liquid fluorocarbon in an absorption zone maintained at superatmospheric pressure to preferentially absorb the desired component in the fluorocarbon. Unabsorbed constituents of the gaseous mixture are withdrawn from the absorption zone. Liquid fluorocarbon enriched in the desired component is withdrawn separately from the zone, following which the desired component is recovered from the fluorocarbon absorbent.
