Acute Exposure Guideline Levels for Selected Airborne Chemicals: Vol 1

Within the Bhopal catastrophe of 1984, nearly 2,000 citizens dwelling close to a chemical plant have been killed and 20,000 extra suffered irreversible harm to their eyes and lungs following the unintentional unencumber of methyl isocyanate. This tragedy served to concentration overseas realization at the desire for governments to spot harmful ingredients and help neighborhood groups in making plans the best way to care for emergency exposures.

There was a complete absence of any troublesome "hot spots". In a d d i t i o n , the t r a n s i e n t temperature p r o f i l e s during heat-up and cool-down were a l s o uniform and s t a b l e . With these encouraging r e s u l t s , i t was decided to scale-up the f l u i d - b e d process f u r t h e r . A 100 B/D f l u i d - b e d program has been formulated to demonstrate h o r i z o n t a l scale-up. H o r i z o n t a l Scale-Up of F l u i d Bed. The 100 B/D p i l o t p l a n t w i l l provide a d d i t i o n a l i n f o r m a t i o n f o r design of a commercials c a l e , f l u i d - b e d process.
