De-Nitrogen and Suphurization Transfer Agent (FP-DSN)
Model NO.: FP-DSN
FP-DSN de-nitrogen/suphurization transfer agent mainly consist of spinel structure composite metaloxide. It has the capability of converting suphur and decrease nitrogen. Most of FP-DSN is used in FCC unit in the refinery, and can decrease SOX and NOX contents in FCC flue gas efficiently. The manufacture and commercial application of FP-DSN shows that the transfer agent is advanced in domestic. FP-DSN was inspected by Petro-China Co. In 2002, and has been used in many petrochemical companies. Product Characteristics It has high activity and hydrothermal stability. The converting rate of SOX is above 60%, the NOX removal rate is more than 70%. The SOX and NOX contents in FCC flue gas is significantly reduced, this ensures long period of safe and reliable operation for FCC, decreasing air pollution. It can bring social and economic benefit remarkably.
