Abstract: An arrangement for a falling film type reactor uses corrugated plates to improve the distribution and dispersion of the gaseous reactant into the liquid. Corrugated plates introduce increased turbulence for promoting better distribution and dispersion of the gas. Corrugation angles can be varied to suit the fluid flow properties of the liquid reactant. The reactor arrangement can also include heat transfer channels defined by the corrugated plates in an alternate arrangement of heat transfer channels and gas liquid contacting channels. The corrugations may also be varied to suit the particular heat transfer requirements of the reactions. The corrugated plates are spaced apart in the contacting channels to prevent localized film contact and placed in contact in the heat exchange portion to stabilize the plate elements defining the corrugations.

Abstract: Metal oxide is produced by heating a metal salt of a carboxylic acid to a predetermined temperature, which varies with a raw material, lower than 300null C. In the case of using zinc acetate as the raw material, when heated in dry helium gas, it is sublimated and decomposed to produce no zinc oxide. In contrast, when heated in a mixture gas of nitrogen gas and water vapor with a programming rate of 5null C./min, the weight loss begins around 110null C. and has been completed around 230null C., at a water vapor partial pressure of 17.9 kPa, to produce zinc oxide. If keeping the temperature approximately constant when the weight loss begins, zinc oxide is produced around 115null C. with a high degree of crystallinity. A metal may be any one of zinc, cadmium, indium and copper. A carboxylic acid may be any one of formic acid, acetic acid, propionic acid and 2-ethylhexanoic acid.

Abstract: In a method of purifying contaminated liquids and gases, a continuous surface film (31) is produced by means of a nozzle (15) and is simultaneously irradiated by a suitable radiation source (17), e.g. an UV lamp. The surface film (31) is discharged as a falling or trickling film (33) which is also exposed to the radiation. A gas for purification is passed through the surface film (31). In these conditions the pollution particles and other pollutants in the gas are absorbed by the liquid. The advantage of the process described is that decomposition of the pollutants can take place both in the gas phase and in the liquid phase. Gas pollutants which are not decomposed in the gas phase are absorbed by the liquid, where they are finally decomposed. With the present invention liquids and gases can be treated simultaneously.

Abstract: In an essentially horizontal totally enclosed cylindrical wiped-wall polymer reactor having an essentially horizontal polymer flow, a pool of polymer in its lower portion, and driven wheels to create high surface area in the polymer to facilitate evaporation of volatiles from the polymer, the improvement comprising a freewheeling drag wheel driven by the driven wheels, with a wiping means mounted on the driven wheels and actuated by the drag wheel to wipe the entire internal circumference of the cylindrical reactor. The drag wheel generates a force to urge the wiping means outward against the internal circumference of the reactor. The force is generated by the drag of the pool of polymer on the drag wheel. This keeps the wall of the reactor wiped with a fresh film of polymer. The process and apparatus is particularly adaptable to driven wheels and drag wheels eccentrically mounted in the reactor.
