Removal of particulate: Even fine-grained particles are arrested in baghouse or pocket filters. Different filter media are available, depending on temperature and dust type. The dust collected in the filter is cleaned and discharged with jets of compressed air.
Removal of sticky particulate (e.g. tar) and aerosols: CTP’s prefilters are filled with high temperature-proof ceramic saddles which generate a turbulent flow and allow for a rapid bake-out of deposits. Due to the depth and the volume of the filter packing particles, tar and aerosols are removed from the waste gas to a high degree.
The gas removed from biogas digestion or fermentation units can be heavily contaminated with foam particles, various particulate matter and water vapour. A pre-filtration of the gas (often adequate enough) can be achieved with the use of an ennox gravel filter.
Collect gases and particulate matter for laboratory analysis with the Thermo Scientific™ ChemComb 3500 Speciation Collection Cartridge. This flexible sampling device is made up of a single cartridge, which contains a well-characterized inlet with a PM-2.5 or PM-10 impactor; up to two honeycomb denuders for the removal or collection of ...
