Spent Acid Recovery Equipment
Integrated Spent Acid Recovery Equipment
Industrial spent acids and acidic effluent are mainly generated from processes such as nitration, esterification, sulfonation, alkylation, catalysis, and gas drying, as well as titanium dioxide production and steel pickling.
The system enables the purification and concentration of spent acids, including sulfuric, hydrochloric, and phosphoric acids, as well as acidic effluent, facilitating acid reuse and recovery.
Two modules are available: spent acid purification and recovery, and spent acid concentration and recovery, selectable based on specific requirements.
Spent Acid Purification and Recovery
Acid-resistant metal-ion membrane separation removes suspended solids, organic matter, and metal ions from spent acid, producing purified acid for reuse and enabling metal recovery.
Spent Acid Concentration and Recovery
Recycled acid is concentrated using acid-resistant membranes and mild-heat evaporation technology to produce concentrated acid and distilled water.
Product Features
Efficient Recovery
The special acid-resistant metal ion separation membrane is adopted for acid purification, with the acid recovery rate exceeding 85%.
High Concentration
The integrated acid purification system removes impurities from acid at concentrations of up to 25%. After concentration, it can produce 30–65% sulfuric acid, 15–25% hydrochloric acid, or 60–85% phosphoric acid according to specific requirements.
Stable & Reliable
Proprietary technology prevents clogging in spent acid evaporators, ensuring stable and reliable operation.
Superior Purity
The integrated system achieves over 95% metal ion removal, producing purified recycled acid with minimal residual metal ions. The recycled acid can be returned to production without compromising process performance.
