Brine Purification for Ion Membrane in Chlor-Alkali Industry
Brine used in the Chlor-alkali industry is electrolysed using ion membrane technology. The ion membranes have stringent limits in ppb level for alkaline earth metals in brine In order to keep effective membrane operations. So, SEPLITE® Chelating resins are used to control impurities at desired level after filtration step
Sunresin Brine Decalcification Solution
The typical chelating resins are based on polystyrene matrix, with weak acid group, in macro porous structure, cation exchange resins :
SEPLITE ® LSC710 - minodiacetate functional group in sodium form
SEPLITE ® LSC750 - Aminomethyl phosphonic acid functional group in sodium form
SEPLITE ® Chelating Resins have unique porosity and surface area that gives excellent operating capacities. They could remove the harmful metal ions effectively, such as calcium Ca2+, magnesium Mg2+, strontium Sr2+, Barium Ba2+, Nickel Ni+, and protect the ion membrane and electrolyzer cell.
Characteristics of SEPLITE® LSC 750 and LSC 710
1. Strong Resistance to osmotic shock
Strong resistance to wear and penetrate, low wastage in ≤5% annual supplement, stable kinetics performance.
2. High operating capacity
Both resins show a high operating capacity for the removal of ions like Ca2+ ，Mg2+ ，Sr2+, resulting into a long cycle times.
3. Easy regeneration
Particle size in a narrow distribution leads a excellent regeneration operation kinetics performance
4. Extensive compatibility
Good compatibility for major electrolytic cell in market, likeAKCC Japan, Uhde, Chlorine engineers, AGC Japan,Blue staretc
