Cast Iron Sections by National-U.S. Cool 400 tons of H 2 S0 4 per day K e r m a c ' s new u r a n i u m mill makes its own sulphuric acid for leaching ores right a t t h e site, from molten recovery sulphur carried from W e s t Texas b y insulated t a n k truck. T h e acid plant, designed b y Leonard Con struction Co., a M o n s a n t o subsidiary, is t h e largest in t h e U . S. using recovery sulphur, a n d yields 9 8 % conversion, sulphur t o sul p h u r i c acid. " T h e sulphur is converted t o SO2 in a sul p h u r burner, a n d t o SO3 in a four-pass vana dium pentoxide converter before delivery t o a n a b s o r p t i o n t o w e r for c o n v e r s i o n i n t o 99.15% sulphuric acid. Diluted t o 9 3 % , t h e acid is cooled from a b o u t 250° t o 90° F . in a h e a t exchanger comprised of National-U.S. C a s t I r o n Sections before delivery t o stor age t a n k s . National-U.S. C a s t I r o n Sections are used in most sulphuric acid plants because of thenproved resistance t o hot, concentrated H2SO4; t h e y a r e easily assembled in a n y stacking a r r a n g e m e n t for t h e desired t o t a l transfer sur face area.
