American chemical engineer

American chemical engineers were not very well equipped to address such sudden problems in their industry. A. D. Little s formulation of unit operations, which appeared in 1915, could have but a limited impact on the growing organic industry because, in practice at least, it largely ignored purely chemical problems (23). In retrospect, this notion of unit operation appears as one which responded extremely well to the industrial demands of a rapidly disappearing past - namely those of a heavy chemical industry based on minerals and petroleum refining. 

Chemical Marketing Reporter for June 25, 1979, carried an advertisement of Hydrocal, S.A., Geneva, Switzerland, which announced the availability of "unique new Maillard flavors", manufactured by Frutarom, Ltd., Haifa, Israel. The owner of this operation is Robert Aries, the American chemical engineer who became expatriate in about 1955, and who returned to the United States in 1979. 

Christine Grant Two hundred and twenty-five women. There are 26 African-American chemical engineering faculty in the country, and five are women. So, I joke with people I say, Me and my four friends. I have been doing this for 10 years. The other four women include an associate professor at Northeastern and an assistant professor at MIT and there is a woman at the University of Iowa and one at the University of Maryland. None of us is a full professor. These are statistics that I keep on the African-Americans and women in chemical engineering. 

In 1940 the British Purchasing Commission of the Ministry of Supply arranged with American Cyanamid for the erection of a 1625-ton/month plant at Welland, Canada. The application of American chemical engineering design teams made this a successful enterprise which was in full production by 1941 and its output by 1943 had been raised to 2300 tons/month. The production of cordite N using this picrite was investigated in the United States and Canada and led to the adoption of picrite propellants by the United States in 1944. 

A. G. Bachman (American Chemical Engineering Company, CT) Peroxyesters. 

A. G. Bachman American Chemical Engineering Co. is the exclusive worldwide manufacturer of Aerobic Acrylic Adhesives. Elosol, Ltd. of Zurich, Switzerland, supplies our formulations to the European Economic Community. We are negotiating with a number of potential licensees in the Far East. 

Andrew G. Bachmann has served as President of the American Chemical Engineering Company since founding it in December of 1979. He previously worked at Allied Product Corp. and Loctite Corp. Mr. Bachmann has authored or coauthored several patents in the field of structural adhesives and microencapsulation, and has extensive experience in the chemistry and medical uses of cyanoacrylates as surgical adhesives. He earned his B.S. and M.S. in Chemistry at the University of Richmond and his M.B.A. in Finance and Marketing from the University of Hartford. 

Platforming (Vladimir Haensel) American chemical engineer Haensel invents platforming, a process that uses a platinum catalyst to produce cleaner-burning high-octane fuels. 

Thomas Kilgore Sherwood (1903-1976) an American chemical engineer whose primary research area was mass transfer and its interaction with flow and with chemical reaction. 

Chilton, Cecil Hamilton (1918-72) An American chemical engineer who co-edited the Chemical Engineers Handbook with Robert H. Perry (1924 78). He was senior advisor at the Battelle Memorial Institute, Columbus, Ohio. Having completed the 5th edition, he died following heart surgery before its publicationin 1973. 

Chilton-Colburn analogy A widely used analogy from heat momentum, and mass transfer analogies. Also known as -factors, they are used to determine an unknown transfer coefficient when one of the other coefficients is known. It applies to fully developed turbulent flow in pipes, and relates mass and heat transfer coefficients, and friction factors. It was proposed by and named after American chemical engineers Thomas H. Chilton (1899-1973) and Allan P. Colburn (1904-55). 

Erfoar-Maddox correlation An empirical method used for the design of distillation columns that relates the number of ideal stages for a given separation and reflux ratio to the minimum number at total reflux and the minimum reflux ratio. The minimum reflux ratio corresponds to an infinite number of stages to bring about separation. It is named after American chemical engineers John H. Erbar and Robert N. Maddox. 

Gilliland equation An empirical equation used to estimate the number of stages required in a distillation column. It uses the minimum number of stages as well as minimum and actual reflux ratios in the calculation. It is named after American chemical engineer Edwin Gilliland (1909-73) who was professor of chemical engineering at MIT. 

Gumey Lurie charts. They are named after American chemical engineer Hoyt C. Hottel (1903 98) who was professor of chemical engineering at MIT. 

B refers to the flow at the bottom and D at the top. x is the mole fraction and subscripts F, B, and D refer to the feed, bottom, and top, where LKand HKare the light and heavy key components. It is named after American chemical engineer Chalmer Gatlin Kirkbride (1906-98). 

It is named after American chemical engineer Warren K. Lewis (1882-1975). See lykov NUMBER.

Rushton turbine A type of impeller used for gas dispersion such as in biochemical reactors and consists of a flat disc with six vertical flat blades mounted on the circumference (see Fig. 54). It therefore provides radial-flow mixing. It is named after American chemical engineer John Hetuy Rushton (1905-85), who was noted for his work on mixing. There have been many subsequent modiflcations and improvements to the basic design. 

Aliphatic chlorofluorocarbons known as CFCs have wide applications in refrigeration, air-conditioning, aerosols, foam blowing and others considered as wonder chemicals of twentieth century. They were discovered by Thomas Midgley, an American chemical engineer in the year 1930 and subsequently...
