Double bank arrangement

The mixer-settler developed by the U.S. Standard Oil Development Company is similar in principle to the Holley Mott extractor, but a box type of construction is adopted with a double bank arrangement, as used... 

Double-pipe exchangers are often piped in complex series-parallel arrangements on both sides. The MTD to be used has been derived for some of these arrangements and is reported in Kern (Process Heat Transfer, McGraw-Hill, New York, 1950). More complex cases may require trial-and-error balancing of the heat loads ana rate equations for subsections or even for individual exchangers in the bank. 

The disproportionation of olefins first reported by Banks and Bailey ) and - as a special case - the ring-opening polymerization of cycloalkenes 3) comprise a re-arrangement of the carbon skeleton of the olefins by opening and closure of double bonds. Thus the reaction - generally referred to as inetathosls reaction - is a trans-alkylidenation reaction.
