Phosphogypsum Decomposition & Recycling Process

Phosphogypsum Decomposition & Recycling Process

The recycling process can treat phosphogypsum and produce two products cement and sulfuric acid, recycling the sulfur and Cacium from gypsum.
ECOSA^?-From H₂S/SO₂?to H₂SO₄ A wet basis sulphuric acid process

ECOSA^?-From H₂S/SO₂?to H₂SO₄ A wet basis sulphuric acid process

ECOSA^? is a sulfur recovery technique aiming at producing H₂SO₄ , by treating H₂S sour gas, producing H₂SO₄and plenty of steam byproduct.
DSR?- Flue gas desulfurization and SO₂ removal technology

DSR?- Flue gas desulfurization and SO₂ removal technology

DSR process is a desulfurization method to recover SO2?in flue gas, which has outstanding effect in environmental protection. The emission could meet the required “ultra-low emission requirement”, which leads to SO2?less than 35mg/Nm3?and even lower as required.
S-Plus?-Claus with ultra-low emission TGT process

S-Plus?-Claus with ultra-low emission TGT process

Claus process is a matured low cost sulfur recovery process widely used in treating H₂S containing sour gas of coal chemical and petrochemical industry. However, Claus process is plagued by problems such as limited sulfur recovery rate and tail gas treating to meet emission standard.
ERSA?-Effective Recovery Of Spend Acid

ERSA?-Effective Recovery Of Spend Acid

ERSA^TM , a proprietary technology of Keyon Process, is dedicated to regenerating spent sulfuric acid from industrial applications such as alkylation process, in which this sort of spent acid has been increasingly generated and difficult to dispose of.
