Ecosystems builds non plugging Scrubber
High efficient removal of dust combined with H2S is archieved at the rendering plant of Sonac Burgum The Netherlands. A total of two DynaWave® scrubbers are installed: Design data:
Gas flowrate : 160000 Nm3/hTemparture : 50 oCMax. : 60 oCH2S content : 80 ppmvDust content : 50 mg/m3 This scrubber was build by ACS and designed by MECS with a vertical vessel containing one chevron demister allowing no plugging.
