This higher-alloy and graphite constructed hydrochloric acid (HCl) recovery system was designed by Sabic. It can handle up to 24 m3/hr of liquid feed and separate out the organics, water, and HCl in aqueous form. The system includes a main distillation column for HCl removal, four HCl absorbers, an HCl regeneration column, and an HCl water removal column.
The previous service was for the recovery of 3% HCl in a wet phenol stream.
