Spent sulphuric acid regeneration (SAR) process

The hot combustion gases are cooled in a high-pressure boiler and, in some cases, a downstream superheater or radiant heat exchanger, which recovers heat for the conversion section of the plant. The radiant heat exchangers are generally used for small plants (less than 100 MTPD), while steaming equipment is used for larger capacity plants.
