Application of powered resin precoat filter in Direct Air-cooled Supercritical Units
The principle and process characteristics of powered resin precoat filter are introduced and the process flows and parameters are discussed through an engineering example. Running data was collected during the period of unit’s integrated starting
and the factors that affect running period are analyzed. Iron removing rate
silicon removing rate and desalting rate in different operating conditions are compared. Several tips are given for the debugging of powered resin precoat filter in the end.
