Considerations i n the Application of Pumps i n Chemical Plants
Methanation of Synthesis Gas over Raney Nickel Calalyst
R. E. Gillmor Eastman Kodak Co., Rochester, N. Y.
H. A. Dirksen and H. R. Linden Institute of Gas Technology, Chicago, Ill.
Selection of the proper pump for a particular application should be based on flow rate, operating temperature and pressure, discharge pressure required by the process, normal pump suction head, properties of the fluid being handled, and environmental factors
Improved preparation and handling procedures for the catalyst promise an economical process with high conversions. Effects of major operating variables on methanation process are given
Pump Theory
Catalytical Oxidation of Hydrocarbons
E. J. Serven, Jr. Standard Pump Division, Worthington Corp., East Orange, N. J.
A review of pumping theory can serve as an excellent guide in the design and selection of pumps for chemical service. Article shows how basic theory is applied i n final selection
K. c. Stein, J. J. Freenan, J.
F. Shultz, 1. J. E. Hofer, and R. B. Anderson Bureau o f Mines, Bruceton, Pa.
New chromatographic technique shows that catalysts based on the oxides of cobalt, nickel, manganese, chromium, and iron have good possibilities i n the automobile smog muffler
Synthesis o f Hydrogen Cyanide
T. K. Sherwood, E. R. Gilliland, and S. W. Ing, Jr. Massachusetts Institute of Technology, Cambridge, Mass.
Two methods are described to produce hydrogen cyanide from elements. I n both cases solid carbon is used. Reaction conditions are given
Mechanism of the Water-Isocyanate Reaction
Some N e w Ideas on Oxidation
F. R. Mayo Stanford Research Institute, Menlo Park, Calif.
Implications of recent oxidation research on surface coatings, aging ot rubbers, stability of gasolines, and some polymerization reactions are covered. Development of better antioxidants is discussed.
George Shkapenko, G. T. Gmitter, and E. E. Gruber General Tire & Rubber Co., Akron, Ohio
A study on the hydrolysis of ;-tolyl isocyanate confirmed and extended the postulated mechanism of Naegeli. Also a quantitative relationship for various isocyanate consuming reactions is given
A Cascade Refrigeration System for -85' C. S. Herrick General Electric Co., Schenectady,
C. Process Cooling
Preparation OF Glass Paper C. E. Huckoba and J. C. Geddes, Jr. University of Florida, Gainesville, Fla.
Inherent properties of glass fibers require special processing techniques. Factors affecting paper manufacture are discussed, and suitable processing equipment suggested
N. Y.
Article describes a cascade refrigeration system i n which ethane absorbs process heat then rejects it t o Freon-22 which in turn rejects heat to cooling water. Flooded evaporators, nonlubricated compressors, and automatic control are unusual features of this system
A Friction Factor Plot for Smooth Circular Conduits, Concentric Annuli, and Parallel Plates John Lohrenz, and Fred Kurata University of Kansas, Lawrence, Kan.
A n Improved Commercial Fluorine Cell C. A. Powell, R. E. Cable, and W. K. Henderson Union Carbide Nuclear Co., Paducah, Ky.
Two novel fluorine-cell anode connections which have increased cell lifetwo to five times have been developed. Connectionssimplifyoperations by reducing number of expensive overhauls needed and increasing cell on-stream time
Experimental data correlate well by this friction factor plot which was developed using a new equivalent diameter
The Practical Aspects of Distillation H. W. Haines, Jr. Walter Kidde Engineers, Houston, Tex.
Pfizer and International Trade John J. Powers, Jr. PRzer International, Inc., New York, N. Y.
A logical, orderly plan for selection and installation of a distillation system, this article bridges the gap between the process design engineer and the project engineer
Many are the problems of a company operating overseas. Here is a report of some of these problems and how they were met and solved Reaction of Ethylene w i t h Aluminum Trialkyls l i q u i d Partition Chromatography for Polyhydric Alcohcls
W. A. Skinner, Ernest Bishop, Paris Cambour, Samuel Fuqua, and
Michael Homiak and J. W. Alexson Johns-Manville Corp., Mansville, N. J.
Peter Lim Stanford Research Institute, Menlo Park, Calif.
Data are given for the separation of ethylene glycol and glycerol by liquid chromatography. Technique has potential application i n plant process schemes
Data were obtained on product yield and distribution under varying experimental conditions. Reaction conditions required for economical production of normal primary alcohols from ethylene can be derived
