Abstract: A reaction column contains intermediate sieve plates whose spacing is less than twice the column dia. and whose total hole area is 10-40% of the column cross-section. Specifically, bubbling type gas-liquid reaction column is subdivided internally by sieve plates which are arranged in a demountable module for easy replacement. Each plate is of double construction so that by relative rotation of the two parts the available hole opening may be adjusted to suit the characteristics of the reacting system. The individual hole dia. is pref. >10mm, and the holes are circular; in a 400 mm i/d column the plate spacing is >=200 mm. Used for continuous chemical reaction between counter-flowing gas and liq. or slurry streams, in columns of dia. >400 mm. Reduces back-mixing effect without the complexity of column packing and without the need for reaction systems in cascade.
