Carbon Filtration Membranes

Preliminary of Analytical Monitoring. Most significant VOCs present in the biogas (laboratory analysis) are commonly Acetone when present it is a first sign that there are problems with bacteria’s in the anaerobic digester, MEK (2-butanone) particularly dangerous for membranes used in the upgrading system, because this compound degradants the membranes polymeric material. Aromatics and terpenes are the compounds with the higher concentration (up to 2000 ppm) in the biogas stream styrene, Cumene, α & β pinene, Limonene, • p-Cymene, with p-Cymene 2 ppm: this is an indication that the activated charcoal started to lose its functionality was not removing VOCs as it should.
