KEYON PROCESS Profile for Phosphate Conference
KEYON PROCESS provides low-Opex Phospho-Gypsum Recycling process to phosphoric acid producer and such PGR process can 100% recycle the Phospho-Gypsum(PG) residue and produce cement and sulfuric acid products. The plant is energy-saving to reach the low Opex, making the plant as both ecological and economical profitable to end-user.
The PG recycling demonstration plant designed by KEYON PROCESS has a capacity as 2,000 MTPD phosphogypsum handle ability, which has been in operation for over 10 years. This technology features low energy consumption and operating expense (low Opex). The revenue generated from the sales of cement and sulfuric acid can lead to profitability. We can solve the problem of PG and bring the profit simultaneously based on technology upgrading.
Moveover, KEYON PROCESS provide Wet sulfuric acid process, Amine SO2 adsorption and regeneration process, Spend Acid Regeneration 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 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
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
Our company wins the outstanding contribution award in 2017 given by the government of Shanghai Jinshan district, to recognize our comapny's contribution to local tax revenue.
