Ⅰ. Product feature and applied range
FP-DS Sulfur Shift Additives developed and produced by Sanju is composed of compounding metal oxide in spinel structure.It is mainly used in FCC unit to remove up to 60% SOx from flue gas.It has good flow performance and water-heat stability.Long-term operation for FCC unit is achieved and air pollution is reduced greatly by significant SOx removal from flue gas.
FP-DS has been certified by SINOPEC in 2002 and widely used in many application in China.
