Another Example of Peabody Quench Towers In Action
When you have the problem of cooling high temperature gases in a minimum of space, benefit by the experience of a large oil company. In this company's ethylene plant, a Peabody direct contact quench tower is used to handle cracked gas. Gas enters the quench tower at 600° F and leaves cooled down to 100° F at the rate of 103,500 CFM. Positive mass transfer is achieved in Peabody towers through an exclusive impingement plate design which brings gas and liquid into intimate contact. The fundamental impingement plate design is used in all Peabody towers, but arrangement, number and types can be varied depending upon the application. When you have a problem involving scrubbers consult Peabody.

gram is an extension of the work of E. W. Malmberg at Ohio State University. I n this work, a gasoline engine is equipped with a sampling valve in the cylinder which removes a small portion of the reacting mix ture for a brief instant during some selected part of the engine cycle. Since the sample valve is opened re peatedly at this particular point in the cycle, a steady stream of gas is drawn off. I n this way, com position of the mixture can be deter mined at any desired part of the cycle. The oxidation reaction apparently starts with the formation of hydro peroxides, whose presence in small concentrations at various points in the cycle was demonstrated by Malm berg and coworkers. Under the conditions of their formation, these hydroperoxides are known to react to form carbonyl compounds and other products; Malmberg has as sumed in a number of studies that the yield of carbon compounds can be used as a measure of the amount of preflame reaction. This convenient experimental approach has enabled Malmberg to carry out a fruitful re search program on hydrocarbon com bustion. Now, Ford would like to determine whether Malmberg's initial assumption is correct by using the new tool of gas chromatography. Ford also has a new aid in that it has new pure hydroperoxide com pounds not previously available. Studying engine behavior with commercial fuels and pure hydro carbons has helped bring about the development of some very efficient modern engines. But a major tech nological break-through will come only with new, more fundamental knowledge of hydrocarbon combus tion. A.D.H.
Atomic Weather Weather control could use some very close team work between nuclear physi cists and meteorologists Radioactivity, both natural and man-made, has been put to good use in studying nature's weather secrets. Use of radioactive tracers in particular has already contrib uted quite a bit to the science of meteorology. But, if Lester Machta
