40 AlliedSignal, Ironton, Ohio 100 Koppers, Follansbee, W.Va.
Capacities are highly flexible and actual production depends on the availability of feedstocks.
Advanced Aromatics produces naphthalene from aromatic petroleum fractions. AlliedSignal and Koppers recover naphthalene from coaltar. Recochem, a coaltar naphthalene producer, can run a dual feedstock system at its Napierville plant. AlliedSignal completed a debottlenecking in the second quarter of 1997 to raise its capacity from 85 million pounds per year to 100 million. Earlier this year, the company sold certain assets of its tar refining business to Reilly Industries Inc., but AlliedSignal continues naphthalene operations at Ironton, using feedstocks from Reilly and other sources.
