Spent Acid Regeneration Units
Heat recovery in spent acid regeneration units.
Where the heat is
What the boiler has to do
- Resist the acid dew point of a wet SO2 gas
- Stay clean under fouling deposits, with provision for online or self-cleaning
- Corrosion-resistant construction, with materials such as stainless steel where the gas demands it
- Components such as filters, heat exchangers, pumps and scrubbers included as the unit needs
- Modular or single-piece design, depending on need
- Economiser and superheater stages to complete the steam system


What we supply
- Process gas waste heat boilers for spent acid regeneration units
- Economisers and superheaters
- The boiler on a 1,000 TPD unit, one of the world's largest in operation

Waste Heat Recovery Boilers
For Spent Acid Regeneration Unit (SARU)
The manufacturing of SARUs varies depending on the specific unit and the process it is intended for. In general, the units are made from corrosion-resistant materials such as stainless steel, and they may include components such as filters, heat exchangers, pumps, and scrubbers. The manufacturing process typically involves the assembly of these components into a single unit, with the specific design determined by the type of spent acid being regenerated and the desired output. The manufacturing process may also include quality control testing and validation of the unit’s performance.
It is important to note that the regeneration of spent acids can be a complex process and should be performed by trained professionals using properly designed and maintained equipment.
