SRC-BL
purestar
SRC-BL columnar activated carbon is manufactured from bituminous coal through grinding, extrusion with binder, high-temperature steam activation, and alkaline impregnation. The caustic treatment creates active sites for chemisorption of acidic sulfur compounds.
Designed specifically for hydrogen sulfide, mercaptan, and organic sulfide removal in wastewater treatment facilities, biogas upgrading, and oil & gas processing operations.

Q1: What is the H₂S removal mechanism?
A: SRC-BL uses alkaline impregnation (typically KOH or NaOH) to chemically react with H₂S, forming stable metal sulfides through irreversible chemisorption.
Q2: How does SRC-BL compare to iron sponge for H₂S removal?
A: SRC-BL offers higher H₂S capacity per unit volume, lower weight, and easier handling than iron sponge, though iron sponge may be more economical for very high H₂S concentrations (>1000 ppm).
Q3: Can SRC-BL remove other sulfur compounds?
A: Yes, SRC-BL effectively removes carbonyl sulfide (COS), carbon disulfide (CS₂), and various mercaptans common in biogas and wastewater streams.
Q4: What is the typical bed life in biogas applications?
A: At typical biogas H₂S levels (500-2000 ppm), bed life ranges from 6-12 months depending on flow rate and target outlet specifications.
Q5: Is spent SRC-BL hazardous waste?
A: Spent carbon containing metal sulfides may be classified as hazardous depending on local regulations. Disposal should follow applicable waste classification procedures.
