Abstract: Aiming at the regeneration problem of metal powder filter in S Zorb unit, a filter regeneration technology was developed and it has achieved good application effect on the key filter ME101 in S Zorb unit. This technology removes the particulates in the pores of the filter material and restores its filtration performance through physical and chemical regeneration. The filter performance is improved significantly after the filter element of ME101 is regenerated. The test results of gas flux under laboratory conditions show that the circulation performance of the filter element is ameliorated obviously; the flux of the filter element exceeds 90% of the new one; and the effect of the filter element after running for 12 months is similar to the new one after regeneration. These all lead to notable economic benefits in industrial application.

Key words: S Zorb, filter element, regeneration, filter
