  • The tank is vented through a minimum 3" vent pipe to the bottom of the scrubber stack.

  • The HCL fumes are dispersed throughout the 1" tower packing. The tower packing pall rings are coated with a graphite/inorganic salt to enhance HCL droplets.

  • In the upper part of the stack is a 6" thick demister to capture fugitive HCL droplets and additional HCL absorption.

  • To prevent droplets of HCl  solution escaping while blowing takes place, a 45 degree scraper ring is at the top.
