Other Technologies. Ethylbenzene can be recovered from mixed Cg aromatics by superfractionation. This technology was first practiced by Cosden Oil Chemical Company in 1957 (Big Spring, Texas), based on a design developed jointly with The Badger Company. Several superfractionation...

Celobric An anaerobic wastewater treatment process, suitable for treating high concentrations of organic substances. Developed by Hoechst Celanese Chemicals Group and the Badger Company, and used in seven installations in 1993. 

SOHIO (BP AMERICA AFTER 1970) The specialty that Standard Oil of Ohio commercialized was developed by another SEP, the Badger Company, which, in Spitz s words, was the most experienced U.S. contractor in the application of fluid bed technology. Mastering that technology, Sohio so lowered the cost of acrylonitrile that it became the dominant American producer and world licenser, but made no attempt to go into acrylic fiber manufacturing. In the United States, its strength continued to rest on the intermediate acrylonitrile.23... 

Application. Both the Tomich and the 2iV Newton-Raphson methods are proven methods and have been applied often. The Tomich method was part of the GMB system of The Badger Company, Cambric, Massachusetts, and is in many in-house simulators. Both methods are best for wide- or middle-boiling s iarations. Because one of the equations in the 2N Newton-R hson method is a dew- or bubble-point equation, it may work better for middle or more narrow-boiling mixtures than the Tomich method. Both methods have also been eq>plied to absorber-strippers, thou an SR method is still the best method for the most wide-boiling absorber-strippers. Because of the full Jacobian more numbers to manipulate), for columns over 50 stages these methods will use excessive computer time and memoiy. Also, the solution of the Jacobian is prone to failure when the number of stages is high, and so these methods are not recommended for tall columns.
